Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     This invention relates to an infrared photographing device, an infrared processing device, and an infrared photographing application field and, more particularly, to an infrared photographing device and an infrared photographing method. 
     Description of the Related Art 
     Thermal image photographing devices are widely applied in fields such as an industrial field, and regular infrared detection for power equipment and buildings is an important part in requiring based on condition. 
     An infrared thermal image is different from a visible image. In the photographed visible image, the object to be photographed may be determined according to the information in the image, such as a color, a nameplate, or a shape. However, a photographed specified object cannot be easily determined according to information in an infrared thermal image. For example, the photographed specified object cannot be effectively recognized via a color or a nameplate. Thus, a user may omit objects during photographing. 
     The infrared detection is heavy work. Taking a substation with power of 500 KV as example, there are usually dozens of equipment areas, and there are dozens of objects requiring infrared detection in each equipment area. There are many similar objects to be photographed, and the similar objects may be the same or different types. For example, in a substation, there are different multiple groups of the objects of a switch type in an equipment area, and the multiple groups of the objects are usually next to each other. In the objects of the same group, there are still three different objects with the same shape and with different phase numbers A, B, C. Since the different objects of the same type are almost the same in the infrared thermal image, a user may miss objects and may be confused during photographing, thereby reducing efficiency. When photographing at different angles is performed or multiple units (the unit may be a specified element or a specified part) of the same object are photographed, this problem is intensified. 
     At present, photographing personnel select an object to be photographed according to subjective experience, because of the above reasons, causing low detection efficiency and high working strength, and further causing incorrectly photographing and omissions of the objects. 
     In addition, at present, a file name of a thermal image file acquired by a thermal image photographing device via photographing is generated according to time or a serial number. To save and analyze subsequently, and to differentiate thermal image files to which the objects correspond, during infrared detection, users are necessary to record object information according to cognitive of the objects or a scene nameplate. The present common record mode may be a manual mode for recording a file name of a thermal image file and the corresponding object information, or a mode for attaching phonic annotation of object information on the scene to a thermal image file. These modes cause inconvenient operation and errors, affect a photographing speed, and cause a heavy subsequent straighten workload. 
     Since thermal imaging detection technology is applied, there are no proper means to conveniently realize an information instruction of an object. The users are often confused in photographing. Technical personnel in the field often try to solve the problem. For example, a thermal image photographing device with a GPS device may provide GPS instructing information during photographing of a power route. However, a user may not easily understand the specified object to be photographed according to the GPS information and cannot correspond to the specified object when there are multiple objects at the same position to be photographed respectively. The above prior art fails to solve the omission problem during photographing. Thus, how to guide the users to photograph an infrared thermal image is a problem. 
     Therefore, an infrared photographing device, capable of providing the object instructing information of the objects to be photographed for the users, is needed. The users can photograph the thermal image according to the object instructing information, thereby solving the present problem. Further, when the object instructing information is provided for the users to photograph the object, the errors and inconvenient operation caused by manual record of the object information may be solved. 
     BRIEF SUMMARY OF THE INVENTION 
     This invention provides an infrared photographing device and an infrared photographing method. Based on multiple object information, representing the objects to be photographed, the object information from the multiple object information is designated as special object information when photographing, and object instructing information acquired by the special object information is specially displayed.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of the invention are described hereinbelow. In a first embodiment of the invention, an infrared photographing device (called a thermal imaging device for short hereinbelow) with a thermal image photographing function is taken for example. It is also applicable to an infrared photographing device continuously receiving thermal imaging data, such as a personal computer, a personal digital processing device, or other processing devices. 
     Further, the called thermal imaging data may be thermal image AD data as an example. In addition, the thermal imaging data is not limited to AD data of the thermal image, and may be image data of an infrared thermal image, array data of temperature values, or compressed data thereof or of the above various mixed data. 
     The embodiments of the invention are described according to drawings in detail. The embodiments described hereinbelow are used for understanding the invention better and do not limit the scope of the invention, and different modes may be changed in the scope of the invention. 
       FIG. 1  is a block diagram showing a thermal imaging device according to the first embodiment.  FIG. 2  is an outline diagram showing the thermal imaging device according to the first embodiment. 
     A thermal imaging device 13 includes a photographing part 1, an image processing part 2, a display controlling part 3, a display part 4, a communication I/F 5, a temporary storage part 6, a storage card I/F 7, a storage card 8, a flash memory 9, an operation part 11, and a control part 10. The control part 10 is connected with the corresponding parts via a control and data bus 12, and is responsible for overall control of the thermal imaging device 13. 
     The photographing part 1 includes an optical part, a lens driving part, an infrared detector, and a signal preprocessing circuit, which are not shown. The optical part is composed of infrared optical lens, and is used for focusing received infrared radiation on the infrared detector. The lens driving part drives the lenses to perform focusing or zooming operation according to a control signal of the control part 10, and the optical part may also be manually regulated. The infrared detector, such as a refrigerating or non-refrigerated infrared focal plane detector, converts the infrared radiation passing through the optical part to electrical signals. The signal preprocessing circuit, including a sampling circuit and an AD conversion circuit, performs signal processing such as sampling and automatic gain control for the signals read from the infrared detector in a specified cycle and converts the signals to digital thermal imaging data (thermal image AD data) via the AD conversion circuit. In the embodiment, the photographing part 1 is as an example of a photographing part and is used for photographing to acquire the thermal imaging data. 
     The image processing part 2 is used for performing specified processing for the thermal imaging data acquired by the photographing part 1. The processing of the image processing part 2 may be modification, interpolation, pseudo-color, compression, or decompression, which is the processing for converting to the data suitable for displaying and recording. The image processing part 2 may be realized by a DSP, other microprocessors, or a programmable FPGA, or may be integrally formed with the control part 10 or the same microprocessor. The processing of the thermal imaging data generating the infrared thermal image may be pseudo-color processing. In detail, in one embodiment, a corresponding range of a pseudo-color plate is determined according to a range of AD values of the thermal imaging data or a setting range of the AD values, and the particular color value to which each AD value of the thermal imaging data corresponds in the range of the pseudo-color plate is used as the image data of the corresponding pixel position in the infrared thermal image. In addition, gray scaling for the infrared image may be as a special example of the pseudo-color processing. In addition, based on the instruction record by the control part 10, the image processing part 2 is used for compressing the thermal imaging data to acquired compressed thermal imaging data according to specified compression processing, and then the thermal imaging data is record to a record medium such as the storage card 8. 
     The display controlling part 3 allows the display part 4 to display the image data stored in the temporary part 6, based on the control of the control part 10. In the embodiment, in a normal mode, the infrared thermal images generated by the thermal imaging data acquired by photographing are displayed continuously. In an information mode, the specially displayed object instructing information and the infrared thermal image (including a dynamic infrared thermal image and a static infrared thermal image) are displayed at the same time. In a playback mode, the infrared thermal image read and expanded from the storage card 8 is displayed. In addition, different kinds of setting information may also be displayed. In detail, in one embodiment, the display controlling part 3 includes a VRAM, a VRAM control unit, and a signal generating unit. Based on the control of the control part 10, the signal generating unit reads image data, read from the temporary storage part 6 and stored in the VRAM, regularly from the VRAM via the VRAM control unit, and generates display signals such as video signal output to be displayed on the display part 4. In the embodiment, the display part 4 is as an example of the display part 4. However, the invention is not limited thereto. The display part 4 may further be other display devices connected with the thermal imaging device 13, and the thermal imaging device 13 may not include the display device in itself. Obviously, when the thermal imaging device 13 do not include the display device in itself, the control part 10 can also control the image data to be displayed and output. For example, the image data to be displayed (the control part 10 and the display controlling part 3 are as an example of the display controlling part) may be output via an image output interface (for example different kinds of wired or wireless image output interfaces such as an AV port or RJ45 port). The display controlling part controls to allow the display part to display and to display the output. The display controlling part 3 may be integrally formed with the image processing part 2 or the control part 10. 
     The communication I/F 5 may be an interface for connecting the thermal imaging device 13 and an external device such as an external computer, a storage device, or a thermal imaging device, according to communication specifications such as USB,  1394 , or network. 
     The temporary storage part 6, such as a RAM or DRAM volatile storage, is a buffer storage for temporarily storing the thermal imaging data output from the photographing part 1, and is a working storage of the image processing unit 2 and the control part 10 for temporarily storing the data processed by the image processing part 2 and the control part 10. However, the invention is not limited thereto. A storage or register included by a processor such as the control part 10 or the image processing part 2 may also be defined as a temporary storage medium. 
     The storage card I/F 7 is used as an interface of the storage card 8. The storage card I/F 7 is connected with the storage card 8 as a rewritable nonvolatile storage, which can be detachably installed in a groove of the main body of the thermal imaging device 13 and can record data such as the thermal imaging data according to the control of the control part 10. 
     The flash memory 9 is used for storing control programs and different kinds of data used in different control. 
     An information storing part, for storing multiple object information, may be a storage medium in the thermal imaging device 13, such as a nonvolatile storage medium, i.e. the flash memory 9 and the storage card 8, or a volatile storage medium, i.e. the temporary storage part 6, and further may be other storage mediums connected with the thermal imaging device 13 wiredly or wirelessly, such as other devices connected with the communication I/F 5 wiredly or wirelessly, i.e. other storage devices or storage mediums in other photographing devices or computers. Preferably, the object information may be prestored in the thermal imaging device 13 or in the nonvolatile storage medium connected with the thermal imaging device 13. 
     The object information is the information related to the object, such as the information representing a position, a type, and a number of an object. In addition, different kinds of information, such as an attribution unit, a classified grade (such as a voltage grade or an importance grade), a model, a manufacturer, performance and characteristics, a passed photographing or repairing record, a manufacturing date, or a service life, related to an object, may be taken for example. The information, such as for generating the object instructing formation, included in the object information, may facilitate a user to determine the object to be photographed. 
     In one preferred embodiment, the object information may be composed of different classified information. In  FIG. 5 , an exemplary list  5001  shows object information stored in the information storing part in one embodiment. Each of the object information is composed of attribute information of some specified attributes. For example, the object information  500  “substation 1 equipment area 1 equipment I phase A” may include the attribute information “substation 1” to which a substation attribute  501  corresponds, the attribute information “equipment area 1” to which an equipment area attribute  502  corresponds, the attribute information “equipment I” to which an equipment type attribute  503  corresponds, and the attribute information “phase A” to which a phase attribute  504  corresponds. However, the invention is not limited thereto. The object information may be stored in other modes except the classified mode. 
     The operation part 11 is used for a user to perform switch instructing operation, record instructing operation, or to input setting information, and informs operation signals to the control part 10, and the control part 10 performs the corresponding program according to the operation signals from the operation part 11. For example, the operation part 11 may include a record key 01 (configured for the record instructing operation), a switch key 02 (configured for the switch instructing operation of the object information), a focusing key 03, an enter key 04, and a cross key 05, as shown in  FIG. 2 . However, the invention is not limited thereto. A touch screen 06 or a phonic part may be used for realizing operation. 
     An infrared photographing method (an information mode) is described hereinbelow. In the embodiment, the control part 10 is as an example of a sequence determining part, an information designating part, a display controlling part, and a process counting part. In the embodiment, a scene of infrared detection for power equipment in an equipment area 1 ( 1101 ), an equipment area 2 ( 1102 ), and an equipment area 3 ( 1103 ) in a substation 1 by users in  FIG. 11 , is taken for example. Before photographing formally, a data file of the object information as shown in the exemplary list in  FIG. 5  is prestored in the flash memory 9 (also in the storage medium such as the storage card 8). The embodiment is described according to  FIG. 3  to  FIG. 11 . 
     The control part 10 controls the whole action of the thermal imaging device 13, and the control part 10 may be realized by a CPU, a MPU, a SOC, or a programmable FPGA. The flash memory 9 stores the control programs and different data used in different control. The control part 10 performs control of multiple modes via the control programs. After the power is on, the interior circuit of the control part 10 is initialized. Then, a standby photographing mode is entered. That is, the photographing part 1 acquires thermal imaging data via photographing, the image processing part 2 performs specified processing for the thermal imaging data acquired by the photographing part 1, to be stored in the temporary storage part 6, and the control part 10 controls the display controlling part 3 to continuously display infrared thermal images in a dynamic image mode on the display part 4. In this state, the control part 10 performs the control to continuously monitor if other modes are switched according to the predetermined condition or the shutdown operation is performed. If yes, the corresponding processing is performed. In  FIG. 4 , the control steps of the information mode are described as follows. 
     In step S 101 , the control part 10 performs the control to continuously monitor if a user selects the information mode via the operation part 11. When the selection of the information mode is detected, step S 102  is performed. 
     In the step S 102 , a sequencing factor of the information object is set. 
     The control part 10 controls to allow the display part 4 to display a setting interface including a plurality of setting options as shown in  FIG. 3 , such as a group setting option  301  configured for setting a group sequence, a sequencing factor option  302  for setting a sequencing factor of the object information, a filter condition option  303  for setting a filter condition, an information display setting option  304 , and a determining option  300  for determining the settings, and then continuously detects whether a user selects one of the setting options for setting or selects the determining option  300 . If one of the setting options is selected, a corresponding setting interface is entered. After the corresponding setting is finished and determined, return to the setting interface as shown in  FIG. 3 , and the control part 10 continuously detects whether the user selects one of the setting options for setting or selects the determining option  300 . Then, when the selection of the determining option  300  is detected, step S 103  is performed. 
     In the embodiment, the user selects the sequencing factor option  302 , and then, in response to the operation, the control part 10 allows the display part 4 to display a sequence setting interface  6000  as shown in  FIG. 6 . The user sets a sequencing factor of the object information according to a substation distribution as shown in  FIG. 11 . In the embodiment, the display part 4, the operation part 11, and the control part 10 are as an example of a sequence setting part. 
     Further, the control part 10 transfers the object information stored in the flash memory 9 to the temporary storage part 6, and the transferred information may be all attribute information or specified part attribute information of the object information. In addition, the object information can be transferred to the temporary storage part 6 when the power is on. 
     A sequence setting part is used for users to set a sequencing factor of the object information. The sequence setting part includes a keyword determining unit for determining a keyword related to a sequence of the objects and a sequencing factor determining unit for determining the sequencing factor of the keyword. The sequence setting part is used for acquiring the sequencing factor of the object information according to a sequencing factor of a first keyword or the sequencing factor of the first keyword combined with a sequencing factor of an auxiliary keyword. The sequencing factor may be a sequence or a sequencing rule, and the sequencing rule may be a number sequencing rule, a letter sequencing rule, a Chinese phonetic letter sequencing rule, a Chinese stroke sequencing rule, or a sequencing rule acquired after manual sequencing for the keyword by the users. 
     When the object information to be sequenced is the object information with different first keywords, the sequence setting part is used for setting the sequencing factor of the first keyword as the sequencing factor of the object information. When the object information to be sequenced includes multiple object information with the same first keyword, the sequencing factor of the object information is determined according to a combination of the sequencing factor of the first keyword and the sequencing factor of the auxiliary keyword. A keyword of the first sequencing factor is called the first keyword, the sequencing factor of the auxiliary keyword at least includes a sequencing factor of a second keyword, and the keyword of the second sequencing factor in the object information is called the second keyword. When there is the multiple object information with the same first keyword and the same second keyword, the sequencing factor of the auxiliary keyword at least includes sequencing factors of the second keyword and a third keyword, the keyword of the third sequencing factor in the object information is called the third keyword, and so on. 
     The keyword determining unit is used for determining a keyword related to a sequence. For example, the keyword related to the sequence may be determined according to one or more embodiments as follows. When there are the first keyword and auxiliary keyword, the same or different embodiments may be performed. 
     In one embodiment, based on the object information stored in the information storing part, a keyword of the attribute information of the specified attribute in the object information is enquired and acquired, and the enquired keyword is determined as the keyword related to the sequence. 
     In addition, based on the object information stored in the information storing part and a keyword enquiring condition, the keyword of the attribute information of the specified attribute in the object information satisfying the keyword enquiring condition is enquired, and the enquired keyword is determined as the keyword related to the sequence. 
     In addition, the keyword may be prestored for the users to select, and then the keyword selected by the user may be determined as the keyword related to the sequence. 
     In addition, by determining a keyword attribute, the keyword satisfying the keyword attribute may be determined as the keyword related to the sequence. For example, when the object information is associated with time information (for example, a data file may be a log file including the object information and time), the keyword attribute (such as a time attribute and so on) may be provided for selection, and the keyword (the time) satisfying the attribute may be determined as the keyword related to the sequence, based on the keyword attribute (such as the time attribute) selected by a user. 
     In addition, a default keyword may be determined as the keyword related to the sequence. 
     In addition, a keyword input by a user may be determined as the keyword related to the sequence. 
     The sequencing factor determining unit is used for determining a sequencing factor of a keyword. For example, the sequencing factor may be determined according to one or more embodiments as follows. When there are the first keyword and the auxiliary keyword, the same or different embodiments may be performed. 
     In one embodiment, the sequencing factor is prestored for users to select, and a sequencing factor selected by a user is determined as the sequencing factor corresponding to the keyword. In addition, the sequencing factor may be default. In addition, the sequencing factor of the keyword may be acquired via the sequencing operation (including the sequencing factor input by the user) of the user. 
     In detail, in this embodiment, based on the object information stored in the information storing part, the first keyword of the attribute information of the specified attribute in the object information is enquired and acquired, and the sequencing factor of the first keyword is determined according to the operation of the user. The control part 10 allows the display part 4 to display the sequence setting interface  6000  as shown in  FIG. 6 . An equipment area setting option  601 , an equipment type setting option  602 , and a phase setting option  603  are configured as menu options representing keyword enquires and sequencing factor settings. As shown in a sequence setting interface  6001 , when the equipment area setting option  601  is selected (may be default), the control part 10 enquires the keyword of the attribute information of the equipment area attribute of the object information, to acquire an equipment area keyword (the first keyword) list  605 . Then, based on the sequence between the first keywords (an equipment area 1, an equipment area 2, and an equipment area 3) set by the user, the sequencing factor of the first keywords is determined. The sequence in a sequence list  604  may be numbers keyed in, or may be set by selecting the keywords in the equipment area keyword list  605  and dragging via a cross key or a touch screen. 
     In the embodiment, the keyword of the attribute information of the equipment area is used as the first keyword. As the object information to be sequenced includes multiple object information with the same first keyword, the sequencing factor of the object information may be determined according to the combination of the sequencing factors of the first keyword and the auxiliary keyword. 
     The keyword determining unit enquires the auxiliary keyword of the attribute information of the specified attribute in the object information satisfying a keyword enquiring condition, based on the object information stored in the information storing part and the determined keyword enquiring condition. The keyword enquiring condition may be one of the first keywords determined before. When there are auxiliary keywords including the second keyword or more, the keyword enquiring condition may be one of the first keywords determined before and one keyword of the auxiliary keywords on each grade. However, the invention is not limited thereto. The keyword enquiring condition may be keyed in. 
     Further, when a user selects the equipment area 1, the control part 10 determines the equipment area 1 (one of the first keywords, the keyword with an underline in an equipment area keyword list  605  in a sequence setting interface  6002 ) as the keyword enquiring condition. The control part 10 acquires a keyword (the second keyword) of the attribute information of the equipment type by enquiring the attribute information of the equipment type of the object information satisfying the keyword enquiring condition “equipment area 1”, further to display an equipment type keyword list  607 . The user sets a sequence of the equipment types to acquire a sequence in a sequence list  606 . Then, taking “equipment I” selected by the user as one of the keyword enquiring conditions (the keyword marked by an underline in an equipment type keyword list  607  in a sequence setting interface  6003 ), the control part 10 acquires an equipment phase keyword list  609  by enquiring the attribute information of the equipment phase of the object information satisfying the keyword enquiring conditions “equipment area 1” and “equipment I”, and acquires the sequence in a sequence list  608  by setting the sequence of the phases. Then, the sequences of the equipment type and equipment phase in the equipment area 1, the equipment area 2, and the equipment area 3 are set in a similar way. When the setting of the sequencing factor is finished, the enter key 04 of the operation part 11 is pressed to determine the sequence, thus to return to the setting interface as shown in  FIG. 3 , and then the enter key 04 of the operation part 11 is pressed again, to determine the determining option  300 . The sequencing factor to which the object information corresponds is acquired as shown in an exemplary list in  FIG. 7 , and the sequencing factor of the object information is record in the temporary storage part 6 or record in the flash memory 9, such as a data file of the object information attached with the sequence or a configuration file of the sequencing rule for subsequent use. 
     In the embodiment, based on the object information stored in the information storing part, the first keyword of the sequence is enquired. However, if a filter condition for determining the object information is set (or default) before, the filter condition may be configured as one keyword enquiring condition of the keyword (including the first keyword and the auxiliary keyword). 
     The advantages of enquiring the keyword of the attribute information of the specified attribute to set the sequencing factor is to avoid inconvenience of sequence adjustment caused by displaying a large amount of object information and the corresponding set sequence on the display part. Further, the sequence keyword acquired by enquires may be simplified, and inconvenience of sequence setting caused by the display of redundant information may be avoided via the keyword enquiring condition. 
     In the step S 103 , the sequence of the object information is determined. 
     A sequence determining part is used for determining a sequence of the object information stored in the information storing part. When the sequencing factor is a sequencing rule, the sequence determining part is used for the object information stored in the information storing part, such as extracting a keyword and sequencing the object information according to the sequencing rule of the keyword, thus to determine the sequence of the object information. When there are a plurality of keywords, the sequencing is performed according to the first keyword and rule, and then the object information with the same first keyword is sequenced according to the second keyword, and so on. 
     In the embodiment, since the sequencing factor set in the step S 102  is based on the sequence of each attribute information of the object information stored in the information storing part, the object information may be sequenced according to the sequence of each attribute information, thus to determine the sequence of each object information. If a data file of the object information attached with the sequence is directly generated in the step S 102 , there is no need to sequence the object information. 
     In addition, the step (S 102 ) for setting the sequencing factor may not be necessary, and the sequence may be determined according to a prestored sequencing factor, such as a default sequencing factor. In addition, in one embodiment, the information storing part (such as the flash memory 9) prestores the object information attached with sequence information, and the sequence determining part determines a sequence of the object information followed by subsequent switch according to the sequence information attached in the object information. The attached sequence information may be identified sequencing information, such as numbers, letters, codes, or other identified sequencing information. The sequence information may be attached as the attribute information of the object information or may be attached as index information to which the object information corresponds. The object information may be stored according to the specified addresses in the data file or the storage medium, which is considered as one way of attachment of the sequence information. 
     The object information may be sequenced according to a default sequencing rule (such as the time attribute of the object information) thus to determine the sequence of the object information. In addition, the object instructing information generated by a specified amount of the object information may be displayed on the display part, and the sequence may be determined by dragging to sequence the object instructing information via a cross key or a touch screen. 
     In step S 104 , the object information as special object information is designated. 
     An information designating part (the control part 10) is used for designating the object information as the special object information according to the object information stored in the information storing part, and the special object information is used for acquiring object instructing information displayed specially. In one preferable embodiment, based on the sequence, the object information “substation 1 equipment area 1 equipment I phase C” in the first place of the sequence is designated as the special object information. 
     The invention is not limited thereto. In other embodiments, the control part 10 monitors if there is an operation instruction for selecting the special object information. When the operation instruction is determined, the object information to which the selected object instructing information corresponds is designated as the special object information. A display controlling part is used for controlling to allow the display part to display a specified amount of the object instructing information based on the object information stored in the information storing part. The information designating part is used for designating the object information as the special object information based on the selection of a user. For example, in the object instructing information as shown in a display interface  801  in  FIG. 8 , the user may select one of the object instructing information via the operation part 11, and the control part 10 designates the object information, to which the object instructing information corresponds, as the special object information. In addition, the user may enter into a new display interface of the object instructing information to select the object instructing information by turning pages or moving rollers. 
     In step S 105 , the thermal imaging data acquired by the photographing part 1 is transferred to the temporary storage part 6. The image processing part 5 performs specified processing such as pseudo-color processing for the thermal imaging data photographed by the photographing part 1 to acquire image data of the infrared thermal image, and the image data is stored in the temporary storage part 6. 
     In step S 106 , the control part 10 is used for controlling to allow the display part 4 to display the infrared thermal image generated by the thermal imaging data and simultaneously to specially display the object instructing information acquired according to the special object information designated by the information designating part. 
     In the embodiment, the object instructing information is displayed with the infrared thermal image together on the display interface, and may be superimposed on the infrared thermal image and/or not superimposed on the infrared thermal image. 
     The special display may be that only the object instructing information acquired according to the designated special object information is displayed, as shown in  FIG. 9 . 
     The special display may be that the object instructing information acquired according to a specified amount of the object information, which is not limited to the special object information, is displayed. The object instructing information acquired according to the designated special object information is displayed specially in a display mode different from that of other object instructing information. In one preferred embodiment, the display controlling part may control to allow the display part to display the infrared thermal image generated by the thermal imaging data and simultaneously to display the object instructing information acquired by the specified amount of the object information according to the sequence, based on the object information stored (determined when a task is determined) in the information storing part and the sequence of the object information determined by the sequence determining part. The object instructing information acquired according to the designated special object information is displayed specially in a display mode different from that of other object instructing information. 
     As shown in a display interface  801  in  FIG. 8 , the control part 10 controls to display the object instructing information acquired by the specified amount of the object information in a sequence. An underline is used to mark “substation 1 equipment area 1 equipment I phase C”, which is different from other object instructing information. In addition, the difference of displaying positions, colors, backgrounds, sizes, typefaces, or word instructions, which is convenient for users to distinguish, may be regarded as the special display mode different from that of other object instructing information. 
     In one preferable embodiment, the display controlling part hierarchically displays specified information for generating the object instructing information in the object information. That is, to display according to the specified hierarchy and the attribute information to which each hierarchy corresponds. The hierarchical display may be displayed according to a tree-like mode, as shown in an object information bar  1001  in  FIG. 10 , the control part 10 divides the object instructing information into specified three hierarchies according to the attribute information of the specified attribute of the substation, the equipment area, the equipment type, and the phase, further to display according to the specified positions, and further the specially displayed object instructing information is superimposed on the infrared thermal image, facilitating observation of the users. 
     In detail, in one embodiment of the display control, the image processing part 2 is controlled to synthesize the image data of the infrared thermal image generated by the thermal imaging data acquired by photographing and the image data of the object instructing information acquired by the designated special object information, and the synthesized image data is stored in the temporary storage part 6. Then, the display control part 3 is controlled to display the synthesized image data on the display part 4. In  FIG. 9 , the synthesis is to allow the object instructing information to be superimposed on the infrared thermal image. In addition, when there is other specified object instructing information, the image processing part 2 is controlled to synthesize the image data of the infrared thermal image generated by the thermal imaging data acquired by photographing, the image data (when there is a specially displayed mark, the image data with the mark is included, such as an underline of the object instructing information in  FIG. 8 ) of the specially displayed object instructing information acquired by the designated special object information, and the image data of other specified object instructing information. The display controlling part 3 is controlled to display the synthesized image data on the display part 4, as shown in  FIG. 8 , and the synthesis is to combine the object instructing information, other object instructing information, and the infrared thermal image, which is displayed at different areas and does not overlap each other or does not have little overlapping. Other instructing information may be a specified amount of object instructing information, process information, a sequence, or instructing information such as data or battery capacity to be displayed by the display part 4. 
     The object instructing information acquired according to the object information may be acquired according to the whole of the object information or the specified part information, and the information for acquiring the object instructing information in the object information may be predetermined. The serials numbers of the sequence to which the object information corresponds may be displayed or not. 
     The control part 10 as a process counting part is used for counting the photographing process information, such as process information  803  displayed in the display interface  801  and process information  804  displayed in the display interface  802 , according to the amount of the object information (the determined object information when a task is determined, or according to serial numbers of a sequence) stored in the information storing part and the present designated special object information. In  FIG. 8 , the serial numbers of the sequence of the specially designated object information are displayed, and the serial number of the sequence and the sum “15” of the displayed object information may form the process information. 
     In step S 107 , the control part determines whether there is switch instructing operation. If no, the steps S 105  to S 107  are repeated, representing the collective display of the object instructing information and the dynamic infrared thermal image (continuously synthesized). If yes, step S 108  is performed. 
     A user uses the specially displayed object instructing information “substation 1 equipment area 1 equipment I phase C” as the instructing information of the present object, thus to examine and photograph the corresponding object. 
     The user finishes the photographing of the corresponding object via the cognition of the object or inspection of the equipment signboard, according to the object instructing information “substation 1 equipment area 1 equipment I phase C” in the display interface  801  in  FIG. 8 , and then the user presses the switch key 02 of the operation part 11, thus to realize the switch instructing operation via one-key operation. The object instructing information includes the information representing the identity of the object. In the embodiment, the users are free of watching the object information as shown in the display interface  801  to select or enquire, and the operation is simple. 
     In addition, even if there is no switch instructing operation of the operation part 11, the control part 10 may control to perform the step S 108  automatically based on the specified switch condition, such as, when satisfying a specified time interval is determined, when a temperature value of a thermal image exceeds a specified threshold value, or when trigger signals of a device such as other sensors connected with the thermal imaging device 13 are received. The specified switch condition may include that, the switch designated processing may be performed when other specified conditions are satisfied at the same time, such as satisfying the specified time interval or the temperature value of the thermal image exceeding the specified threshold value, even if there is the switch instructing operation of the operation part 11. Obviously, the specified switch condition may be different conditions configured in advance. 
     In the step S 108 , the control part 10 determines whether the task is finished. 
     The control part 10 determines whether the last object information in the sequence is designated. If no, return to the step S 104 , and at that moment, the designated special object information is switched according to the sequence. If yes, the information mode at this time is end, and the letters “the task is over” may be displayed on a screen. Then, return to a standby state of the thermal imaging device, to wait for operation of the users to enter into other modes. In addition, a specified sequence starting point such as a sequence starting point may be switched thus to perform cycle photographing. 
     In detail, in one embodiment, the information designating part (the control part 10) adds one to the serial number of the sequence, to which the special object information designated before switch corresponds, and then determines whether the last one in the sequence is finished. If no, the object information, to which the serial number of the sequence acquired after the serial number of the sequence is added to one corresponds, is designated as the special object information. If yes, log out. In addition, it is not necessary to determine whether the last object information in the sequence is designated, and it may not be determined. When the switch instructing operation is received every time, the object information, to which the serial number of the sequence acquired after the serial number of the sequence is added to one corresponds, is found and designated as the special object information. When it is not found, one is continuously added, and the information mode is end, until the specified time is exceeded or until the control part 10 receives the logout instruction. 
     In the embodiment, return to the step S 104 . The information designating part switches the designated special object information based on the sequence of the object information determined by the sequence determining part, that is, to switch the object information designated as the special object information. 
     In one preferred embodiment, the information designating part switches the single object information designated as the special object information, from the single object information designated as the special object information before switch, to the object information which is the next to the object information designated as the special object information in the sequence (when there is a task determining step, it is a sequence of the object information determined by the task determining part) before switch. For example, in the embodiment, the single object information designated as the special object information may be switched from the single object information “substation 1 equipment area 1 equipment I phase C” designated as the special object information before switch, to the object information “substation 1 equipment area 1 equipment I phase B” which is the next to the object information “substation 1 equipment area 1 equipment I phase C” designated as the special object information in the sequence before switch. 
     The display controlling part controls to allow the display part to display the infrared thermal image generated by the thermal imaging data and simultaneously to display the object instructing information acquired according to the special object information switched and designated by the information designating part in a special display mode. As shown in a display interface  802 , the object instructing information “substation 1 equipment area 1 equipment I phase B” specially displayed is switched. The process information  803  displayed in the display interface  801  changes to the process information  804  displayed in the display interface  802 . Then, the user can photograph the corresponding object according to the specially displayed object instructing information “substation 1 equipment area 1 equipment I phase B”. Thereby, the users can easily photograph along a photographing route L 11  as shown in  FIG. 11 , without missing the objects. 
     In addition, the information designating part switches the single object information designated as the special object information from the object information designated as the special object information before switch, to the object information which is the previous one of the object information designated as the special object information in the sequence before switch. The switch based on the sequence may be performed in a proper sequence or an inversed sequence, and the switch may be set according to the proper sequence or the inversed sequence. 
     In addition, when the information designating part designates two or more adjacent object information in the sequence as the special object information, the information designating part switches a specified amount of the adjacent object information in the sequence designated as the special object information, from the specified amount of the adjacent object information in the sequence designated as the special object information before switch, to a specified amount of the adjacent object information in the sequence with the origin which is the next to the object information designated as the special object information in the sequence before switch. 
     For example, when “substation 1 equipment area 1 equipment I phase C”, “substation 1 equipment area 1 equipment I phase B”, and “substation 1 equipment area 1 equipment I phase A” is designated at the same time, in response to the switch instructing operation, “substation 1 equipment area 1 equipment II phase A”, “substation 1 equipment area 1 equipment II phase B”, and “substation 1 equipment area 1 equipment II phase C” is switched and designated as the special object information. 
     In addition, when the information designating part designates two or more adjacent object information in the sequence as the special object information, the switch may be performed according to an inversed sequence. 
     In the embodiment, a small amount of the object information is described. In practical infrared detection, the number of the objects is large, and the embodiment of the invention can make remarkable achievements. 
     Similarly, for complex equipment or multi-angle photographing situations, related object information may be prestored for the objects (including units or angles) photographed singly, and then be sequenced, thereby avoiding omissions of the photographing parts. 
     In the embodiment, the information mode includes the sequencing factor setting step (the step S 102 ). However, the invention is not limited, and the step S 102  may not be necessary. The sequence of the object information may be determined according to the default sequencing factor, or the sequencing factor may be set and stored separately for subsequent use. 
     According to the above, based on the prestored object information, the sequence of the object information is determined based on the sequencing factor. Then, the special object information is designated, and the infrared thermal image is displayed together with the specially displayed object instructing information on the display part. The displayed object instructing information includes the information representing the identity of the object for a user to determine the object to be photographed. The users can regard the specially displayed object instructing information as the instructing information of the present object, to determine the object to be photographed via cognition of the object or inspection of the equipment signboards, thereby reducing incorrect photograph. When the switch instructing operation is performed, the designated special object information is switched according to the sequence, and the object instructing information acquired according to the special object information designated and switched by the information designating part, thereby greatly reducing incorrect routes or disorder routes and avoiding omissions, further to improve the photographing speed and to reduce the working strength. By displaying the counted photographing process information, the users can arrange the photographing process reasonably. In brief, the first embodiment is one preferred embodiment. Any product in the embodiment of the invention may be not necessary to achieve all of the advantages at the same time. 
     Embodiment Two 
     In this embodiment, the flash memory of the thermal imaging device 13 with the same structure as shown in  FIG. 1 , stores a control program for setting a filter condition and a control program for determining object information (included in a photographing task) according to the filter condition. A scene of infrared detection for power equipment in an equipment area 1 ( 1101 ), an equipment area 2 ( 1102 ), and an equipment area 3 ( 1103 ) in a substation 1 as shown in  FIG. 11  is taken for example. Different from the first embodiment, in this embodiment, a user may divide a photographing task into a plurality of subtasks according to the filter condition, and then may sequence the object information in the subtask, finally to photograph. Suppose a user photographs the objects in the equipment area 1 first, the embodiment is described according to  FIG. 12  to  FIG. 17 . 
     In step S 201 , the control part 10 controls to continuously monitor if a user selects an information mode via the operation part 11. If yes, step S 202  is performed. 
     In the step S 202 , a filter condition is set. 
     The control part 10 controls to allow the display part to display a setting interface as shown in  FIG. 3 . When the user selects a filter condition option  303 , then a filter condition setting interface as shown in  FIG. 13  is displayed on the display part 4, and the user sets and determines the filter condition. Then, when the selection of the determining option  300  is detected, step S 203  is performed. 
     A task setting part is used for users to set a filter condition, and the filter condition is composed of keywords related to the filter condition and a filter logic relation. 
     The task setting part includes a keyword determining unit, a logic determining unit, and a filter condition generating unit. The keyword determining unit is used for determining the keywords related to the filter condition. The logic determining unit is used for determining the filter logic relation of the keywords related to the filter condition. The filter logic relation may be a filter true or false relation of one keyword, or a combination of an AND-OR-NOT logic relation among a plurality of the keywords and the filter true or false relation. The filter condition generating unit is used for generating the filter condition according to the keywords related to the filter condition and the specified filter logic relation. 
     The keyword related to the filter condition may be one keyword or a plurality of keywords. The multiple keywords include a condition representing a keyword range, such as a number range, a letter range, a sequence range, and a time range. In addition, when the object information includes different information related to the object, such as an attribution unit, a classified grade (such as a voltage grade or an importance grade), a model, a manufacturer, performance and characteristics, a passed photographing or repairing record, a manufacturing date, or a service life, the filter condition may be set by determining the keyword according to the above. However, the above information may not be used for generating the specially displayed object instructing information. 
     The keyword determining unit is used for determining keywords related to the filter condition. For example, the keywords related to the filter condition may be determined according to the following one or more embodiments. 
     In one embodiment, for example, the keywords for selection may be prestored, and the keywords related to the filter condition may be determined based on selection of a user. 
     In one embodiment, for example, one or all of the keywords related to the filter condition may be default. 
     In one embodiment, for example, a user may key in the keywords, and the keywords keyed in by the user may be determined as the keywords related to the filter condition. 
     In one embodiment, for example, a selection option of keyword attributes may be provided for selection, and based on the keyword attribute selected by a user, the keyword satisfying the keyword attribute may be determined as the keyword related to the filter condition. Thereby, when part of the object information includes attribute information of a specified attribute, and other object information does not include the attribute information of the specified attribute, the object information may be filtered conveniently. 
     In one preferred embodiment, based on the object information stored in the information storing part, the keyword of the attribute information of the specified attribute in the object information is enquired and acquired. Based on selection of a user, the keyword related to the filter condition may be determined. 
     In the embodiment, the information storing part stores the object information as shown in  FIG. 15 . The control part 10 controls to allow the display part 4 to display a filter condition setting interface as shown in  FIG. 13 , with a substation  1303 , an equipment area  1304 , and an equipment type  1305 , which are configured as keyword menu options representing keyword enquires of the attribute information of the specified attribute. Based on the selection of the equipment area  1304  by the user according to “equipment area 1” photographed at this time, the control part 10 enquires the object information stored in the information storing part to acquire keywords “equipment area 1, equipment area 2, equipment area 3, . . . ” of the attribute information of the specified attribute (the equipment area), thus to allow to display a list  1306 , and by selecting “equipment area 1” therein by the user, the keyword determining unit determines “equipment area 1” as the keyword related to the filter condition. In the embodiment, the display part 4, the operation part 11, and the control part 10 are as an example of a task setting part. However, when there are more types of the keywords of the attribute information of the object information, the operation according to this embodiment may be complicated. 
     In another preferred embodiment, the keyword determining unit is used for determining a keyword enquiring condition, used for enquiring and acquiring the keyword of the attribute information of the specified attribute in the object information satisfying the keyword enquiring condition, based on the object information stored in the information storing part, and used for determining the keyword related to the filter condition based on the selection of a user. The keyword enquiring condition may be one or more keywords related to the filter condition determined before. 
     The control part 10 allows the display part 4 to display a filter condition setting interface as shown in  FIG. 14  during display setting operation. When a user selects a substation  1403  via the operation part 11, the control part 10 enquires a keyword of the attribute information of the substation attribute, based on the object information stored in the information storing part, thereby allowing to display a list  1406 . When the user selects “substation 1” therein, the control part 10 determines “substation 1” as the keyword related to the filter condition. Then, when the equipment area  1404  is selected, the control part 10 determines “substation 1” selected by the user as the keyword enquiring condition, and enquires a keyword of the attribute information of the equipment area attribute of the object information satisfying “substation 1”, thereby allowing to display a list  1407 ″equipment area 1, equipment area 2, equipment area 3″. The user may select the equipment area “equipment area 1”. The control part 10 determines “substation 1” and “equipment area 1” as the keywords related to the filter condition. Obviously, the number of the keywords for selection may be simplified by this way. 
     The logic determining unit is used for determining the filter logic relation of the keywords related to the filter condition. The filter logic relation may be the filter true or false relation when the keyword related to the filter condition is one single keyword, or a combination of the AND-OR-NOT logic relation between multiple keywords and the filter true or false relation when the keywords related to the filter condition are a plurality of keywords. The filter logic relation may be default or may be determined according to settings of the users. 
     In one embodiment of one single keyword, when the keyword related to the filter condition is the single keyword “equipment area 1” as shown in  FIG. 13 , the options “yes”  1301  and “no”  1302  of a photographing condition, are used for setting the filter true or false relation. When “yes” is selected, the filter condition generated by the keyword “equipment area 1” combined with the option, is used for subsequently finding and determining the object information satisfying “equipment area 1” as a photographing task. When “no” is selected, the filter condition generated by the keyword “equipment area 1” combined with the option, is used for subsequently finding and determining the object information which does not satisfy “equipment area 1”. In the embodiment, the logic determining unit determines the filter true or false relation as “yes” according to the default filter true or false relation “yes”. Then, when the user performs determination via the operation part 11, the filter condition generating unit (the control part 10) combines the default filter true or false relation “yes” with the keyword “equipment area 1” selected by the user, to generate the filter condition. When the task is determined, the object information satisfying the keyword “equipment area 1” is found to be as the determined object information. 
     In one embodiment of multiple keywords, when the keywords related to the filter condition are “substation 1” and “equipment area 1” as shown in  FIG. 4 , the logic determining unit determines the filter true or false relation as “yes” according to the default filter true or false relation “yes”, and the logic determining unit determines the logic relation between the keywords “substation 1” and “equipment area 1” as “AND” according to the default logic relation (the relation between keywords of different attributes is “AND”) “AND”. Then, when a user performs determination via the operation part 11, the filter condition generating unit (the control part 10) combines the keywords “substation 1” and “equipment area 1” related to the filter condition with the default logic relation “AND” and the default filter true or false relation “yes”, thus to generate the filter condition. When the task is determined, the object information satisfying the keywords “substation 1” and “equipment area 1” is found to be as the determined object information. However, the invention is not limited thereto. The logic determining unit may be operated by users to set the logic relation (not shown) of the keywords. 
     When the setting of the filter condition is finished, the user may perform determination via the enter key of the operation part, and the generated filter condition is record in the temporary storage part 6 or the flash memory 9 (such as, generating configuration files) for subsequent use. Step S 203  is performed. 
     In the step S 203 , the task determining part is used for determining the multiple object information from the object information stored in the information storing part. The object information designated as the special object information is from the determined multiple object information 
     For example, “substation 1” and “equipment area 1” may be as the filter condition. When the information storing part stores the object information as shown in  FIG. 15 , the object information satisfying the keywords “substation 1” and “equipment area 1” is found to be as the determined object information (such as the object information in  FIG. 16 ). In addition, the object information may be determined according to other specified filter conditions (such as a default filter condition). In addition, when the information storing part prestores multiple data files including the object information, the data files are provided for the users to select and the object information in the data file selected by the user is determined. 
     In step S 204 , a sequence of the object information is determined. 
     In the embodiment, the control part 10 controls to display the object instructing information acquired by the specified amount of the object information according to a default sequencing factor on a specified position of the display part 4, as shown in  1701  in  FIG. 17 . Then, a user adjusts the sequence of the displayed object instructing information via dragging operation through a cross key or a touch screen. In addition, the information such as numbers representing the sequence may be keyed in, to acquire the object instructing information and the sequence as shown in  1702  in  FIG. 17 . In this embodiment, the sequence determining part determines the sequence of the object information to which the object instructing information corresponds, in response to predetermined operation for adjusting the sequence of the object instructing information displayed on the display part. 
     In step S 205 , the special object information is designated. 
     When the sequence adjustment is finished, the user selects the object instructing information “substation 1 equipment area 1 equipment I phase C” as shown in  1702  in  FIG. 17 , and the control part 10 designates the object information to which the object instructing information corresponds, as the special object information. Step S 206  is performed. 
     In the step S 206 , the thermal imaging data acquired by the photographing part 1 is transferred to the temporary storage part 6. The image processing part 2 performs pseudo-color processing for the thermal imaging data acquired by the photographing part 1 to acquire the image data of the infrared thermal image, and the image data is stored in the temporary storage part 6. 
     In step S 207 , the object instructing information acquired by the special object information and the infrared thermal image is displayed on the display part 4 at the same time. 
     In step S 208 , the control part determines whether there is switch instructing operation. If no, the steps S 206  to S 208  are repeated. If yes, step S 209  is performed. 
     In the step S 209 , the control part 10 determines whether the task is finished. 
     If finished, the information instruction photographing mode is end, and return to a standby state of the thermal imaging device, to wait the users for setting and photographing “equipment area 2” and “equipment area 3” again. If not finished, return to the step S 205 , and the switch designating is performed according to the sequence. 
     In the embodiment, the task is set after the information mode is entered. However, the invention is not limited. The task may be set first, for example, the information mode may be entered after generating a new data file. In addition, the task setting may be performed for several times, and different combinations may acquire more embodiments. 
     According to the above, the filter condition of the object information in the photographing task is set, thereby reducing the displayed redundant information, reducing the object instructing information, and facilitating sequence adjustment of the displayed object instructing information. Further, the photographing route is determined in advance, thereby reducing strength, improving efficiency, and avoiding omissions of the objects in the later photographing. 
     Embodiment Three 
     In this embodiment, the flash memory 9 of the thermal imaging device 13 with the same structure as shown in  FIG. 1 , stores a control program for setting a group sequence and a filter condition and a control program for determining object information according to the filter condition. A scene of infrared detection for power equipment with the type “equipment I” in an equipment area 1, an equipment area 2, and an equipment area 3 in a substation 1 as shown in  FIG. 11  is taken for example. In the past, due to different detecting objectives, there is detection for the whole objects in the substation and detection for the objects of a specified type, the objects of the specified type are distributed at different equipment areas, and the users need to find the objects, causing inconvenience. Obviously, the object information may be used as the filter condition, thereby facilitating the photographing by the users. 
     Different from the first embodiment, three data files are stored in the storage card, as shown in  FIG. 21 , and a data file 1 (a list  2101 ) includes object information attached with a sequence and related to the equipment area 1, a data file 2 (a list  2102 ) includes object information attached with a sequence and related to the equipment area 2, and a data file 3 (a list  2103 ) includes object information attached with a sequence and related to the equipment area 3. To plan a photographing route with the best efficiency, a user can set the sequence among the data files according to distribution of the substation, and then may set “equipment I” as the filter condition to photograph. The embodiment is described according to  FIG. 18  to  FIG. 22 . 
     In step S 301 , the control part 10 controls to continuously monitor if a user selects an information mode via the operation part 11. If yes, step S 302  is performed. 
     In step S 302 , a sequencing factor among the data files is set. 
     The control part 10 controls to allow the display part to display the setting menu as shown in  FIG. 3 . When a user selects the group setting option  301  in  FIG. 3 , based on the data files (group) stored in the information storing part, a data file list  1802  as shown in  FIG. 18  is displayed, and the user sets a sequencing factor (a sequence list  1801 ) for the data files in the list. When the setting is finished and determined, return to the setting menu in  FIG. 3 . When the user selects the filter condition option  303  again, step S 303  is performed. 
     The information storing part is used for prestoring multiple groups of the object information. A group sequence setting part is used for setting the sequencing factor among the groups. The group mentioned here is a set of multiple object information with the same group mark, such as a data file or a file folder. In addition, when the group sequence is finished, the sequencing factor of the object information in the same group may be set or examined again. 
     In step S 303 , the filter condition is set. 
     The task setting part is used for users to set the filter condition (of the object information included in the photographing task). 
     The control part 10 allows to display a filter condition setting interface as shown in  FIG. 20 . In one embodiment, based on selection of an equipment type  2001  by the user according to “equipment I” photographed at this time, the control part 10 enquires the object information in the data files 1, 2, and 3 determined in the step S 302 , to acquire the keywords “equipment I, equipment II, equipment III” of the attribute information of the specified attribute (the equipment type), thus to display a list  2002 , and generates the filter condition by combining the default filter true or false relation “yes” and the keyword “equipment I” when the user selects “equipment I”. When the user finishes the setting and determines the determining option  300  in  FIG. 3 , step S 304  is performed. In addition, the filter condition may be determined by other determining methods as mentioned in the step S 202  in the second embodiment. 
     In the step S 304 , the object information and the sequence is determined. 
     Based on the filter condition determined in the step S 303 , the object information satisfying the keyword “equipment I” is found in the data files 1, 2, and 3 to be as the determined object information, and the determined object information and the sequence is displayed as an exemplary list  2104  in  FIG. 21 , by combining the group sequencing factor and the sequencing factor of the object information in each group set in the step S 302 . Compared with the data files 1, 2, and 3 before the task is determined, “equipment area 2”, “equipment II”, and “equipment III” are reduced, and the number of the equipment photographing task is reduced to “6”. Obviously, the photographing route during the specified photographing task is simplified, thereby avoiding finding “equipment I” in “equipment area 2”, and reducing the work strength. 
     In step S 305 , the special object information is designated. 
     The control part 10 controls to designate the object information “substation 1 equipment area 1 equipment I phase C” at the first place of the determined object information attached with the sequence, as the special object information. 
     In step S 306 , the thermal imaging data acquired by the photographing part 1 is transferred to the temporary storage part 6, the image processing part 2 performs pseudo-color processing for the thermal imaging data photographed by the photographing part 1 to acquire image data of an infrared thermal image, and the image data is stored in the temporary storage part 6. 
     In step S 307 , the object instructing information acquired according to the special object information is displayed with the infrared thermal image on the display part 4 at the same time. 
     In step S 308 , the control part determines whether there is switch instructing operation. If no, the steps S 306  to S 308  are repeated. If yes, step S 309  is performed. 
     In the step S 309 , the control part 10 determines whether the task is finished. 
     If finished, the information instructing photographing mode is end, and return to a standby state of the thermal imaging device, to wait for the users to perform operation of other modes. If not finished, return to the step S 305 , the determined object information is switched and designated according to the sequence. 
     In this embodiment, when the user finishes photographing the equipment I in the equipment area 1, the user turns to photograph the equipment I in the equipment area 3, avoiding seeking the equipment I in the equipment area 2. The photographing route of the equipment area 1 ( 2201 ), the equipment area 2 ( 2202 ), and the equipment area 3 ( 2203 ) in  FIG. 22 , changes from L 11  in  FIG. 11  to L 22  in  FIG. 22 . 
     According to the above, by setting the sequencing factor between the groups, accelerating operation for sequencing the groups is provided. By setting the filter condition, the display of the redundant information can be reduced, the displayed object instructing information is more instructive, and further the photographing route is simplified, thereby reducing strength, improving efficiency, and avoiding omissions. Obviously, when the filter conditions of different types are set, more convenience is provided for the users to photograph. If the object information includes attribute information of a history (such as past deficiencies), the users can quickly find related information of the deficient object, facilitating reexamination. 
     Embodiment Four 
     The thermal imaging device 13 with the photographing function in the above embodiment may further be applied to an infrared processing device for receiving and processing the thermal imaging data from outside. In the embodiment, an infrared processing device  100  is as an example of an infrared photographing device. 
     In this embodiment, as shown in  FIG. 24 , a thermal imaging collecting device  101  is erect on a detection vehicle via an extension ladder, and is connected with an infrared processing device  100  via communication wires such as special-use cables, or a local area network consisted in a wired or wireless mode. The users can inspect thermal images of the object via the infrared processing device  100 . The thermal image collecting device  101  is connected with the infrared processing device  100  to form an infrared photographing system in this embodiment. 
       FIG. 23  is a block diagram showing an infrared photographing system including an infrared processing device  100  and the thermal imaging collecting device  101  connected with each other. 
     The infrared processing device  100  includes a communication interface 1, an auxiliary storage part 2, a display controlling part 3, a display part 4, a hard disk 5, a temporary storage part 6, an operation part 7, and a CPU  8  connected with the above parts via a bus and for the whole control. The infrared processing device  100  may be a computer or a special-use processing device. The infrared processing device  100 , based on the control of CPU  8 , receives the thermal imaging data output by the thermal image collecting device  101  connected with the infrared processing device  100  via the communication interface 1. The communication interface 1 is used for continuously receiving the thermal imaging data output by the thermal image collecting device  101 , including the thermal imaging data transferred by a relay device (the thermal imaging data output by the thermal image collecting device  101  is transferred by the relay device), and further may be used as a communication interface for controlling the thermal image collecting device  101 . In the embodiment, the communication interface 1 may be different kinds of wired or wireless communication interfaces on the infrared processing device  100 , such as a network interface, a USB interface, a  1394  interface, or a video interface. The auxiliary storage part 2 may be a storage medium, such as a CD-ROM or a storage card, and a related interface. The display controlling part 3 displays an image on the display part 4 according to the control of CPU  8 . The display part 4 may be a liquid display, and the infrared processing device  100  may not include a display in itself. The hard disk 5 stores programs for control and different kinds of data used in the control. The temporary storage part 6, such as a non-volatile storage, i.e. RAM and DRAM, is used as a buffer storage for temporarily storing the thermal imaging data received via the communication interface 1, and is also used as a work storage of the CPU  8 . The operation part 7 is used for users to operate. The CPU  8  controls the whole action of the infrared processing device  100  and performs different related processing, such as specified processing for the received thermal imaging data, i.e. modification, interpolation, pseudo-color, synthesis, compression, and decompression, which is the processing for converting to the data suitable for displaying and recording. For example, when the received thermal imaging data is compressed thermal image AD data, the specified processing may be decompression and corresponding pseudo-color processing for the thermal imaging data received by the acquiring part via the CPU  8 . When the received thermal imaging data is compressed image data of the infrared thermal image, the image data of the infrared thermal image may be acquired via decompression. When the communication interface 1 receives the analog infrared thermal image, the image data of the digital infrared thermal image may be acquired after AD conversion via related AD converting circuits. 
     The thermal image collecting device  101  includes a communication interface  10 , a photographing part 20, a flash memory 30, a temporary storage part 50, an image processing part 40, and a CPU  60 . The CPU  60  controls the whole action of the thermal image collecting device  101 , and the flash memory 30 stores control programs and data of different kinds used in different control. The photographing part 20 is used for acquiring the thermal imaging data via photographing, the temporary storage part 50 is used for storing the processed data temporarily, the image processing part 40 may compress the photographed thermal imaging data, and the CPU  60  controls to output the processed thermal imaging data via the communication interface  10 . 
     The structure in the thermal imaging device 13 except the photographing part 1 is generally the same with that in the infrared processing device  100 . Obviously, acquiring the thermal imaging data from outside is also suitable for this embodiment. Therefore, the description of the embodiment is omitted. Obviously, the infrared processing device  100  can be used in coordination with different kinds of thermal image collecting devices with the infrared photographing function, such as different kinds of handheld thermal imaging devices. 
     Other Embodiments 
     In addition, a display unit of the display part 4 may be configured to at least one. There are a display for displaying the infrared thermal image and a display for specially displaying the object information. The display control at the same time mentioned by the display controlling part may be to display on the same display or different displays at the same time. 
     Preferably, the object instructing information is displayed with the continuous infrared thermal image at the same time. However, the invention is not limited thereto. For example, the display part 4 may display the dynamic infrared thermal image, and when the display instruction of the specified object instructing information displayed specially is received, the object instructing information is displayed with the frozen infrared thermal image at the same time. In addition, the object information and the infrared thermal image may be switched to display. That is, in response to a corresponding instruction such as a display instruction (such as pressing a button representing display of the object information) of the object information, the display controlling part switches the displayed infrared thermal image to the object instructing information acquired according to the special object information designated by the information designating part in a special display mode, then switch designation operation is performed, and the object instructing information after switch is displayed specially, while the infrared thermal image is displayed, in response to the display instruction of the infrared thermal image. In addition, after the special display, blanking may be performed after displaying for specified time or based on operation of users, to avoid occupations of the display screen. In addition, in the embodiment, when a specified amount of the object instructing information is displayed, the switch operation may not be performed, while the users can select the multiple object information displayed according to the sequence. The information designating part designates the object information as the special object information based on selection of the user. By this way, the users can select conveniently. 
     In the embodiment, the information mode includes settings of the filter condition and the sequencing factor. However, the invention is not limited. The settings of the filter condition and the sequencing factor are not necessary, and the object information and the sequence may be determined based on the default filter condition or defaulted sequencing factor. 
     In addition, the filter condition or the sequencing factor may be set separately for subsequent use. For example, the filter condition and the sequencing factor may be set first, further to be stored as a default value or a configuration file for subsequent use, and the object information attached with the sequence may be acquired according to the filter condition and the sequencing factor, such as generating a new data file, then to enter into the information mode. 
     In addition, one preferred mode is to set the filter condition first and then to set the sequencing factor. However, the invention is not limited. The filter condition setting step and the sequence setting step may be performed without distinction of sequence, or may be set at the same time in the same operating interface. In addition, the filter condition or the sequencing factor may be reset. 
     In addition, in the embodiment, the filter condition setting step, the sequence setting step, the task determining step, and the sequence determining step are described step-by-step, or may be described in an instant gradual mode. That is, when the filter condition is set, the task determining part determines the object information according to the filter condition, when the sequencing factor of the keyword is set, the sequence determining part determines the sequence of the object information determined by the task determining part, and when the settings are determined in total, such as determination of the determining option  300  in  FIG. 3 , a step for designating the special object information is performed. 
     Obviously, different groups of the working steps can acquire more embodiments. More embodiments may be acquired according to different combinations of the working modes. 
     In the embodiments, the less object information is described. In practical infrared detection, there are many objects, and the embodiments in the invention may bring remarkable effects. In the embodiment, when the object needs to be photographed from multiple angles, the object information including the photographed angle information may be prestored, and then the sequencing factor of the photographing angle is set during sequencing. 
     In addition, the processing and control function of part or all elements in the embodiments of the invention may be realized via special-use circuits, general processors, or programmable FPGA. Although the function block in the drawings may be realized via hardware, software, or the combination thereof, the structure for realizing the function block may not be set to a one-for-one mode. For example, multiple function blocks may be realized via one software or hardware unit, or one function block may be realized via multiple software or hardware units. 
     In addition, the objects in the power industry are taken as a scene for example, and different industry of the infrared detection is also suitable. 
     The above description is only the embodiments of the invention, and the exemplary description is not for limiting the substantive contents of the invention. Persons having ordinary skill in the art may make other modifications and changes without departing from the scope and spirit of the invention after reading the description.
