SUMMARY OF INVENTION

Technical Problem

In the technology described in PTL 1, identification information and a measured value of a measuring instrument are recognized and the recognition result is stored in the storage unit. In order to grasp a recognition result with respect to a measured value during an inspection, a worker needs to check the result with a processing terminal on hand. However, in such a case, the worker needs to move his/her line of sight from the measuring instrument to the processing terminal, and thus working efficiency may be degraded.

Further, the technologies described in PTLs 2 and 3 display information about identified equipment being stored in a storage unit or the like by reading an identification marker or an RFID tag. Accordingly, in the technologies described in PTLs 2 and 3, a worker cannot grasp, while working, information related to a result of an inspection performed on the equipment at the time of reading the identification marker or the RFID tag.

The present disclosure has been made in view of the aforementioned problems, and an object of the present disclosure is to provide a technology of enhancing efficiency of inspection work.

EXAMPLE EMBODIMENT

First Example Embodiment

A first example embodiment of the present disclosure will be described with reference to drawings.FIG. 1is a functional block diagram illustrating an example of a functional configuration of an inspection assistance device10according to the present example embodiment.FIG. 2is a diagram illustrating an example of an application of the inspection assistance device10illustrated inFIG. 1. For example, the inspection assistance device10is equipped on a glasses type wearable terminal as illustrated inFIG. 2. The glasses type wearable terminal is hereinafter referred to as wearable glasses1. For example, by a worker2wearing the wearable glasses1turning his/her face in a direction of an inspection target3such as a measuring instrument, the wearable glasses1image the inspection target3. The captured image is displayed on a display unit14on the wearable glasses1. Consequently, the worker2checks the image in which the inspection target3is captured, through the wearable glasses1.

The inspection assistance device10according to the present example embodiment includes an image data acquisition unit11, a display control unit12, and a recording control unit13, as illustrated inFIG. 1.

The image data acquisition unit11acquires image data in which an inspection target3is captured. For example, the image data acquisition unit11acquires image data representing an image captured by a camera including a lens and an imaging element. The captured image includes the inspection target3. The image data acquisition unit11may be a camera itself, or may acquire image data acquired by a camera from the camera. The image data acquisition unit11may acquire image data acquired by a camera from a recording unit recording the image data. The image data acquisition unit11provides the acquired image data for the display control unit12.

The display control unit12superimposes information about an inspection result of an inspection target3on an image including the inspection target3, the information being recognized based on image data acquired by the image data acquisition unit11, and causes the display unit14to display the resulting image. The display control unit12receives image data from the image data acquisition unit11and identifies an inspection target3included in an image represented by the received image data. The display control unit12recognizes information about an inspection result related to the identified inspection target3. For example, when the inspection target3is a thermometer, the display control unit12may set temperature as information about an inspection result. Further, for example, when the inspection target3is a thermometer, the display control unit12may set information indicating whether or not temperature is within a predetermined range as information about an inspection result. The display control unit12superimposes the recognized information about the inspection result on the image including the inspection target3and being represented by the image data, and causes the display unit14to display the resulting image.

For example, the display unit14is a lens part of the wearable glasses1as illustrated inFIG. 2, and for example, is provided by a display module transmitting external light and displaying information in accordance with an instruction from the display control unit12; however, the display unit14is not limited to the above. The display unit14may be a module having a function of displaying, on a retina of the worker2, an image being generated by the display control unit12and including an inspection target3, information about an inspection result being superimposed on the image. Thus, the display unit14may have a function of projecting an image generated by the display control unit12, in accordance with control by the display control unit12. The display control unit12may have the function of projecting an image generated by the display control unit12. For example, when the display unit14is set to be a retina, the display control unit12may have a function of superimposing recognized information about an inspection result on an image including an inspection target3and directly projecting the resulting image on the retina.

The recording control unit13records information about an inspection result, the information being displayed on the display unit14, and information about an inspection target3in association with one another. The recording control unit13records information about an inspection result and information about an inspection target3being associated with one another into, for example, a recording medium such as a hard disk drive or paper. For example, information about an inspection target3includes an inspection item for the inspection target3, a normal value of the inspection target3, and information indicating a state of the inspection target3in a normal condition but is not limited to the above.

FIG. 3is a flowchart illustrating an example of a processing flow in the inspection assistance device10according to the present example embodiment. As described inFIG. 3, the image data acquisition unit11acquires image data in which an inspection target3is captured (Step S31). Then, the display control unit12superimposes information about an inspection result of the inspection target3on an image including the inspection target3, the information being recognized based on the acquired image data, and causes the display unit14to display the resulting image (Step S32). Then, the recording control unit13records the information displayed on the display unit14and the information about the inspection target3in association with one another (Step S33).

Thus, the inspection assistance device10according to the present example embodiment can superimpose information about an inspection result on an image represented by image data in which an inspection target3is captured, the information being recognized based on the image data, and display the resulting image on the display unit14on the wearable glasses1. Since the image represented by the image data includes the inspection target3, the worker2wearing the wearable glasses1can grasp the inspection target3and the information about the inspection result of the inspection target3. For example, when information about an inspection result is a measured value of a measuring instrument, the worker2can readily grasp that a measured value displayed on the display unit14is a measured value of an inspection target3.

Further, the inspection assistance device10records information about an inspection result, the information being displayed on the display unit14, and information about an inspection target in association with one another. For example, when information about an inspection target is an inspection item, the inspection assistance device10records an inspection item and information about an inspection result in association with one another. Consequently, for example, time and effort for manually inputting information about an inspection result by use of a terminal or the like by the worker2can be saved. Further, human errors due to manual input can be reduced.

Further, by referring to recorded information, a worker checking an inspection result can readily grasp an inspection item and information about an inspection result. As described above, the inspection assistance device10according to the present example embodiment can enhance efficiency of inspection work.

Second Example Embodiment

Next, a second example embodiment of the present disclosure based on the aforementioned first example embodiment will be described with reference to drawings.FIG. 4is a diagram for illustrating wearable glasses4including an inspection assistance device100according to the present example embodiment. As illustrated inFIG. 4, for example, the inspection assistance device100is equipped on the wearable glasses4. For example, by a worker2wearing the wearable glasses4turning his/her face toward an inspection target3such as a measuring instrument, the wearable glasses4image the inspection target3. The captured image is displayed on a display unit160on the wearable glasses4. Consequently, the worker2checks an image in which the inspection target3is captured, through the wearable glasses4. Further, the wearable glasses4may include an input device200. The input device200will be described later.

FIG. 5is a block diagram illustrating a configuration example of the wearable glasses4including the inspection assistance device100according to the present example embodiment. As illustrated inFIG. 5, the wearable glasses4include the inspection assistance device100, the input device200, the display unit160, and a recording unit170. The inspection assistance device100may be configured to include the input device200, the display unit160, and the recording unit170.

The inspection assistance device100is an example of the inspection assistance device10according to the first example embodiment. As illustrated inFIG. 5, the inspection assistance device100includes an image data acquisition unit110, a display control unit120, a recording control unit130, an acceptance unit140, and an inspection target information acquisition unit150.

The image data acquisition unit110is an example of the image data acquisition unit11according to the first example embodiment. The image data acquisition unit110acquires image data in which an inspection target3is captured. For example, the image data acquisition unit110acquires image data representing an image captured by a camera including a lens and an imaging element. The captured image includes the inspection target3. The image data acquisition unit110may be a camera itself, or may acquire image data acquired by a camera from the camera. The image data acquisition unit110may acquire image data acquired by a camera from the recording unit recording the image data. The image data acquisition unit110provides the acquired image data for the display control unit120.

The display control unit120is an example of the display control unit12according to the first example embodiment. The display control unit120superimposes information about an inspection result of an inspection target3on an image including the inspection target3, the information being recognized based on image data acquired by the image data acquisition unit110, and causes the display unit160to display the resulting image. The display control unit120receives image data from the image data acquisition unit110and identifies an inspection target3included in an image represented by the received image data. A method of identifying an inspection target3by the display control unit120is not particularly limited, and any method may be employed. For example, by comparison between image data acquired by the image data acquisition unit110and image data for identifying an inspection target3, the display control unit120may identify what the inspection target3included in the image data represents.

Then, the display control unit120recognizes information about an inspection result related to the identified inspection target3. A method of recognizing information about an inspection result by the display control unit120is not particularly limited, and any method may be employed. For example, when an inspection target3is a measuring instrument such as a thermometer, the display control unit120may read temperature indicated by the thermometer into a memory and recognize the reading result as information about an inspection result. Further, when an inspection target3is a structure, the display control unit120may calculate a degree of degradation of the structure by calculating the degree from changes in color and texture, and recognize the calculation result as information about an inspection result. A calculation method of a degree of degradation may employ any method, and for example, a variation in color may be set as a degree of degradation.

The display control unit120superimposes the recognized information about the inspection result on an image including the inspection target3, the image being represented by the image data, and causes the display unit160to display the resulting image. An example of information displayed by the display unit160will be described in a separate drawing. The display unit160may be a lens part of the wearable glasses4, similarly to the aforementioned display unit14.

For example, the input device200is a device for inputting an instruction by the worker2. For example, the input device200may be provided by a switch being equipped on the wearable glasses4and being depressible by the worker2, or the like. Further, the input device200may be a terminal being separate from the wearable glasses4and being capable of communicating with the wearable glasses4. Further, for example, the input device200may be an infrared sensor capable of detecting an operation by the worker2, or the like.

The acceptance unit140accepts an instruction (recording instruction) input by the worker2by use of the input device200. The acceptance unit140provides the accepted recording instruction for the recording control unit130.

The inspection target information acquisition unit150acquires information about an inspection target3. For example, information about an inspection target3includes an identifier for identifying the inspection target3, an inspection target name representing the inspection target3, and an inspection item for the inspection target3. The inspection target information acquisition unit150acquires information about an inspection target3, based on image data acquired by the image data acquisition unit110. The inspection target information acquisition unit150may receive image data acquired by the image data acquisition unit110through the display control unit120, recognize an inspection target3by comparing the inspection target3included in the image data with, for example, a dictionary, and acquire information about the inspection target3associated with the recognized inspection target3. Further, the inspection target information acquisition unit150may receive information indicating an inspection target3identified by the display control unit120from the display control unit120, and from the information, acquire information about the inspection target3. Information about an inspection target3may be acquired from image data themselves or may be acquired from the recording unit storing information about the inspection target.

The recording control unit130is an example of the recording control unit13according to the first example embodiment. The recording control unit130records information about an inspection result, the information being displayed on the display unit160, and information about an inspection target in association with one another. The recording control unit130receives information about an inspection target from the inspection target information acquisition unit150and records information about an inspection result, the information being displayed on the display unit160by the display control unit120, and the information about the inspection target in association with one another. While it is assumed that the recording control unit130according to the present example embodiment records the associated information in the recording unit170, the recording control unit130may be configured to record the associated information by outputting the information to paper or another medium. It is preferable that the recording control unit130record information about an inspection result and information about an inspection target when the acceptance unit140accepts a recording instruction. Consequently, only information with respect to which a recording instruction is given by the worker2is recorded, and information determined not necessary to be recorded is not recorded. Accordingly, information necessary in inspection work is recorded, and therefore management efficiency of recorded information can be enhanced.

For example, the recording unit170is provided by a hard disk drive. The recording unit170records information about an inspection result and information about an inspection target associated by the recording control unit130.

FIG. 6is a flowchart illustrating an example of a processing flow in the inspection assistance device100according to the present example embodiment. As described inFIG. 6, the image data acquisition unit110acquires image data in which an inspection target3is captured (Step S61). Then, the display control unit120superimposes information about an inspection result of the inspection target3on an image including the inspection target3, the information being recognized based on the acquired image data, and causes the display unit160to display the resulting image (Step S62).

Further, the inspection target information acquisition unit150acquires information about the inspection target3, based on the acquired image data (Step S63). Step S62and Step S63may be performed simultaneously or may be performed in reverse order.

Next, the acceptance unit140checks whether a recording instruction is accepted (Step S64). When the worker2checking the information displayed on the display unit160inputs a recording instruction by use of the input device200, the acceptance unit140accepts the recording instruction (YES in Step S64). When the acceptance unit140accepts the recording instruction, the recording control unit130records the information displayed on the display unit160and the information about the inspection target3in association with one another (Step S65). When the acceptance unit140does not accept a recording instruction (NO in Step S64), the inspection assistance device100ends the processing. For example, the acceptance unit140may determine that a recording instruction is not accepted when a recording instruction is not accepted for a predetermined time after the display unit160displays the information about the inspection result.

Further, the acceptance unit140may be configured to accept an instruction not to record. In this case, the recording control unit130may record the information displayed on the display unit160and the information about the inspection target3in association with one another when the acceptance unit140does not accept an instruction not to record. With such a configuration, even when there are many pieces of information to be recorded, the worker2can readily sort out information not necessary to be recorded.

Further, when the acceptance unit140does not accept a recording instruction for a predetermined time or the recording unit140accepts an instruction not to record, the image data acquisition unit110may acquire new image data different from the image data acquired in Step S61. Then, the display control unit120may recognize information about an inspection result related to an inspection target3from the new image data. When the acceptance unit140performs as described above, the display control unit120may perform the recognition processing again by use of image data identical to the image data used for recognition in Step S62. At this time, the display control unit120may perform the recognition processing on a condition identical to that used in Step S62(for example, the same recognition parameter) or may perform the recognition processing on a different condition. Alternatively, the display control unit120may perform predetermined correction processing on the image data and perform the recognition processing. Further, when the acceptance unit140performs as described above, for example, the image data acquisition unit110may acquire new image data when a result of performing recognition again by use of the same image data by the display control unit120is identical to the previously recognized result.

Further, the acceptance unit140may be configured to accept a re-recognition instruction by the worker2. For example, when the worker2checks information displayed on the display unit160, determines that the displayed information has an error, and inputs a re-recognition instruction to perform re-recognition, the acceptance unit140accepts the re-recognition instruction. When the acceptance unit140accepts a re-recognition instruction, the image data acquisition unit110may acquire new image data different from the image data acquired in Step S61. Then, the display control unit120may recognize information about an inspection result related to an inspection target3from the new image data. When the acceptance unit140accepts a re-recognition instruction, the display control unit120may perform the recognition processing again by use of image data identical to the image data used for recognition in Step S62. At this time, the display control unit120may perform the recognition processing on a condition identical to that used in Step S62or may perform the recognition processing on a different condition. Alternatively, the display control unit120may perform predetermined correction processing on the image data and perform the recognition processing. Further, when the acceptance unit140accepts a re-recognition instruction, for example, the image data acquisition unit110may acquire new image data when a result of performing recognition again by use of the same image data by the display control unit120is identical to the previously recognized result.

FIG. 7illustrates an example of an image represented by image data acquired by the image data acquisition unit110. As illustrated inFIG. 7, the image70represented by image data acquired by the image data acquisition unit110includes an inspection target3. It is assumed in the description of the example illustrated inFIG. 7that the inspection target3is composed of two thermometers (a thermometer31and a thermometer32). The inspection target3may be an entire measuring instrument including the thermometer31and the thermometer32.

FIG. 8is a diagram illustrating an example of a display screen71displayed by the display unit160. As illustrated inFIG. 8, the display screen71is displaying pieces of information, that is, measured temperature information72being information about an inspection result of the thermometer31constituting the inspection target3and measured temperature information73being information about an inspection result of the thermometer32constituting the inspection target3. The pieces of information is superimposed on the image70illustrated inFIG. 7, displayed on the display unit160. The display control unit120may identify an entire measuring instrument including the thermometer31and the thermometer32, subsequently identify that the inspection target3related to the measuring instrument is composed of the thermometer31and the thermometer32, and recognize a measured temperature of the thermometer31and a measured temperature of the thermometer32. Then, the display control unit120may generate the display screen71acquired by superimposing the measured temperature information72indicating the measured temperature of the thermometer31and the measured temperature information73indicating the measured temperature of the thermometer32on the image70. Positions where the recording control unit130displays the measured temperature information72and the measured temperature information73are not particularly limited and may be arbitrary positions.

The worker2wearing the wearable glasses4can readily grasp information about an inspection result of the inspection target3by checking the display screen71displayed on the display unit160on the wearable glasses4.

Next, information recorded in the recording unit170will be described with reference toFIG. 9.FIG. 9is a diagram illustrating an example of recorded information91recorded in the recording unit170. The recorded information91includes information displayed on the display unit160and information about an inspection target3associated with one another by the recording control unit130. It is assumed in the example illustrated inFIG. 9that the information displayed on the display unit160is a measured value92. Measured values92illustrated inFIG. 9are a measured temperature indicated by the measured temperature information72and a measured temperature indicated by the measured temperature information73that are illustrated inFIG. 8. The pieces of information displayed on the display unit160may be the measured temperature information72itself and the measured temperature information73itself illustrated inFIG. 8. For example, “TEMPERATURE: 7° C.” illustrated inFIG. 8may be included in a measured value92column. Further, it is assumed in this example that the information about an inspection target3includes an inspection target name93indicating a name of the inspection target3and an inspection item94for the inspection target3. As illustrated inFIG. 9, it is assumed that inspection target names93of the thermometer31constituting the inspection target3are “THERMOMETER31” and “THERMOMETER32.” Then, it is assumed that an inspection item94for each of the thermometer31and the thermometer32is “MEASURE TEMPERATURE.” As illustrated inFIG. 9, the recorded information91records a measured value92, and an inspection target name93and an inspection item94in association with one another.

The recording control unit130may associate data represented in the display screen71displayed on the display unit160with the information about the inspection target3, as the pieces of information displayed on the display unit160. Further, the recording control unit130may record the image70in further association with the information about the inspection target3. At this time, for example, the recording control unit130may extract an image of the thermometer31part included in the image70and associate the image of the thermometer31part with the information about the thermometer31.

Further, the recording control unit130may record information indicating a recording instruction accepted by the acceptance unit140in a further associated manner into the recording unit170. Information indicating a recording instruction may be a flag indicating completion of checking or information indicating whether or not a displayed content is correct. Further, for example, when a recording instruction accepted by the acceptance unit140indicates the thermometer31, the recording control unit130may extract an image of the thermometer31part included in the image70and associate the image of the thermometer31part with the information about the thermometer31.

Further, when the input device200is a sound collecting device such as a microphone, the acceptance unit140may accept collected voice data. The recording control unit130may determine the acceptance unit140accepting voice data to be a recording instruction. Further, the recording control unit130may analyze voice data accepted by the acceptance unit140and when voice indicating a recording instruction is included, may record the information displayed on the display unit160and the information about the inspection target3in association with one another. Further, the recording control unit130may record collected voice data in association with the information displayed on the display unit160.

Further, the input device200may detect a worker's action indicating that the worker2performs a predetermined action and provide action information indicating the detected action for the acceptance unit140. Then, the acceptance unit140may accept the action information. The action information may indicate the predetermined action or may indicate an action reacting to contents in the display screen71. The recording control unit130may determine acceptance of the action information by the acceptance unit140to be a recording instruction. Further, the recording control unit130may recognize an action included in the action information accepted by the acceptance unit140, by, for example, comparing the action with a dictionary, and when the action indicating the recording instruction is included in the action information, may record the pieces of information displayed on the display unit160and the information about the inspection target3in association with one another. Further, the recording control unit130may record action information in association with the pieces of information displayed on the display unit160.

Further, for example, information about an inspection target includes an inspection item for the inspection target, a normal value of the inspection target, and information indicating a state of the inspection target in a normal condition but is not limited to the above.

While the display screen71illustrated inFIG. 8includes the measured temperature information72being a measured value with respect to the thermometer31and the measured temperature information73being a measured value with respect to the thermometer32as information about an inspection result, information about an inspection result is not limited to a measured value.FIG. 10is a diagram illustrating an example of a display screen74displayed by the display unit160. The display screen74illustrated inFIG. 10displays information (75,76) indicating whether or not an inspection result is normal as information about an inspection result. When an inspection target3is composed of a thermometer31and a thermometer32as illustrated inFIG. 10, the information (75,76) indicating whether or not an inspection result is normal is a result determining whether or not temperature is within a predetermined range.

Further, an inspection target3is not limited to a measuring instrument.FIG. 11is a diagram illustrating another example of an image represented by image data acquired by the image data acquisition unit110. When the worker2photographs part of a bridge111as an inspection target3, an image112represented by image data acquired by the image data acquisition unit110includes the part of the bridge111as the inspection target3, as illustrated inFIG. 11. Thus, an inspection target may be a structure instead of a measuring instrument. It is assumed that the bridge111has a crack113.

FIG. 12is a diagram illustrating an example of a display screen114displayed by the display unit160. It is assumed in this example that the display control unit120detects the crack113by comparison with a previously photographed image of the bridge111or an image displaying the crack113. In this case, as illustrated inFIG. 12, the display unit160displays the display screen114displaying a mark (an ellipse115in the example inFIG. 12) for grasping a position of the crack113, the mark being superimposed on the image112illustrated inFIG. 11, as information about an inspection result of the bridge111. Thus, the recording control unit130may make a degraded spot of a structure displayed as information about an inspection result in a graspable manner for the worker2. A display method of a degraded spot of a structure is not limited to the ellipse115; and for example, the spot of the crack113may be displayed in a color different from other colors, or another method may be employed.

FIG. 13is a diagram illustrating an example of a display screen116displayed by the display unit160. The display screen116illustrated inFIG. 13displays information117indicating a degree of degradation as information about an inspection result. In this case, the display control unit120may include the information117indicating a degree of degradation in the display screen116by recognizing the crack113from image data and calculating the degree of degradation of the crack113by a predetermined method.

As described above, in the inspection assistance device100according to the present example embodiment, the image data acquisition unit110acquires image data in which an inspection target is captured, and the display control unit120superimposes information about an inspection result of the inspection target on an image including the inspection target, the information being recognized based on the acquired image data, and cause the display unit to display the resulting image.

Thus, the inspection assistance device100according to the present example embodiment can superimpose information about an inspection result on an image represented by the image data, the information being recognized based on image data in which an inspection target is captured, and cause the display unit160on the wearable glasses4to display the resulting image. Since the image represented by the image data includes the inspection target, the worker2wearing the wearable glasses4can grasp the inspection target and the information about the inspection result of the inspection target.

Further, the recording control unit130in the inspection assistance device100records information about an inspection result, the information being displayed on the display unit160, and information about an inspection target in association with one another. For example, when information about an inspection target is an inspection item, the recording control unit130records the inspection item and information about an inspection result in association with one another. Consequently, for example, time and effort for manually inputting information about an inspection result by use of a terminal or the like by the worker2can be saved. Further, human errors due to manual input can be reduced. At this time, it is preferable that the recording control unit130record information about an inspection result and information about an inspection target when the acceptance unit140accepts a recording instruction. Consequently, only information necessary in inspection work is recorded, and therefore management efficiency of recorded information can be enhanced.

Further, by referring to recorded information, a worker checking an inspection result can readily grasp an inspection item and information about the inspection result. As described above, the inspection assistance device100according to the present example embodiment can enhance efficiency of inspection work.

Third Example Embodiment

A configuration of the inspection target information acquisition unit150acquiring information about an inspection target, based on image data, has been described, according to the aforementioned second example embodiment; however, the present disclosure is not limited to the above. Another example of acquisition of information about an inspection target, according to the present example embodiment, will be described. A block having a function similar to a block described in the aforementioned second example embodiment is given the same sign.

FIG. 14is a block diagram illustrating a configuration example of an inspection assistance device101according to the present example embodiment. The inspection assistance device101is equipped on wearable glasses4, similarly to the inspection assistance device100.

The inspection assistance device101includes an image data acquisition unit110, a display control unit120, a recording control unit130, an acceptance unit140, an inspection target information recording unit180, and an inspection target information acquisition unit190. The inspection assistance device101is configured to include the inspection target information acquisition unit190in place of the inspection target information acquisition unit150in the inspection assistance device100and further include the inspection target information recording unit180.

The inspection target information recording unit180records inspection target information.FIG. 15illustrates an example of inspection target information recorded by the inspection target information recording unit180. Inspection target information151includes information about an inspection target3. It is assumed that the information about the inspection target3includes an inspection target name153and an inspection item154, similarly to the aforementioned second example embodiment. Further, the inspection target information151includes an inspection target position152indicating a position of the inspection target3. A notation method of the inspection target position152is not particularly limited, and the inspection target position152has only to be information telling a position.

The inspection target information recording unit180may be provided by a recording device separate from the inspection assistance device101.

The inspection target information acquisition unit190acquires information about an inspection target, based on positional information at the time of capturing image data. The inspection target information acquisition unit190acquires positional information at the time of capturing image data, through the display control unit120. The positional information at the time of capturing image data may be information indicating a position of the wearable glasses4photographing the image data or may be information indicating a position of an inspection target3included in the acquired image data, the position being estimated from the image data.

With regard to a position of the wearable glasses4acquiring image data, for example, the wearable glasses4may receive positional information by use of the Global Positioning System (GPS) and attach the positional information to the image data. Then, the inspection target information acquisition unit190compares the positional information attached to the image data with an inspection target position152in the inspection target information151stored in the inspection target information recording unit180. The inspection target information acquisition unit190acquires, from the inspection target information recording unit180, information about an inspection target3associated with an inspection target position152within a predetermined range from a position indicated by the positional information attached to the image data. In the example illustrated inFIG. 15, the inspection target information acquisition unit190acquires, from the inspection target information recording unit180, an inspection target name153and an inspection item154that are associated with an inspection target position152within a predetermined range from a position indicated by the positional information attached to the image data.

Then, the recording control unit130records the information about an inspection result, the information being displayed on the display unit160, and the information about the inspection target, the information being acquired by the inspection target information acquisition unit190, in association with one another, similarly to the recording control unit130according to the aforementioned second example embodiment.

In the inspection assistance device101according to the present example embodiment, the inspection target information acquisition unit190acquires information about an inspection target, based on positional information at the time of capturing image data. Consequently, for example, even when inspection targets having the same shape exist at a plurality of positions, information about an inspection target included in the image data can be identified. Consequently, the recording control unit130can suitably associate information about an inspection result with respect to the inspection target included in the image data with the information about the inspection target. Accordingly, by referring to recorded information, a worker checking an inspection result can readily grasp an inspection item and information about an inspection result. As described above, the inspection assistance device101according to the present example embodiment can enhance efficiency of inspection work.

Modified Example

Inspection target information recorded by the inspection target information recording unit180is not limited to the form inFIG. 15. In this modified example, another example of inspection target information recorded by the inspection target information recording unit180will be described.FIG. 16is a diagram illustrating another example of inspection target information recorded by the inspection target information recording unit180. Inspection target information161includes information about an inspection target3. It is assumed that information about an inspection target3includes an inspection target name163and an inspection item164, similarly to the inspection target information151. Further, the inspection target information161includes an inspection time162indicating a time when the inspection target3is inspected. A notation method of the inspection time162is not particularly limited, and the inspection time162has only to be information telling a time.

The inspection target information acquisition unit190acquires information about an inspection target, based on time information at the time of capturing image data. The inspection target information acquisition unit190acquires time information at the time of capturing image data through the display control unit120. Time information at the time of capturing image data is information indicating a time when the image data are photographed. Time information at the time of photographing image data may be attached to the image data.

The inspection target information acquisition unit190compares time information at the time of photographing image data with an inspection time162in the inspection target information161stored in the inspection target information recording unit180. The inspection target information acquisition unit190acquires, from the inspection target information recording unit180, information about an inspection target3associated with an inspection time162within a predetermined period from a time indicated by the time information at the time of photographing the image data. In the example illustrated inFIG. 16, the inspection target information acquisition unit190acquires, from the inspection target information recording unit180, an inspection target name163and an inspection item164that are associated with an inspection time162within the predetermined period from a time indicated by the time information at the time of photographing the image data.

Then, the recording control unit130records information about an inspection result displayed on the display unit160and the information about the inspection target, the information being acquired by the inspection target information acquisition unit190, in association with one another, similarly to the recording control unit130according to the aforementioned second example embodiment.

In the inspection assistance device101according to this modified example, the inspection target information acquisition unit190acquires information about an inspection target, based on time information at the time of capturing image data. Consequently, for example, when an inspection target to be inspected varies depending on a time, information about an inspection target included in image data can be identified by comparing time information. Consequently, the inspection target information acquisition unit190can readily acquire information about an inspection target. Further, for example, even when inspection targets having the same shape exist at a plurality of positions, the inspection target information acquisition unit190can identify information about an inspection target included in image data as long as each inspection time is different.

Thus, the inspection assistance device101according to this modified example can enhance efficiency of inspection work, similarly to the inspection assistance device101according to the aforementioned third example embodiment.

For example, the inspection target information acquisition unit190in the inspection assistance device101may acquire information about an inspection target by use of an RFID. For example, the inspection target information acquisition unit190may read an RFID tag attached to an inspection target included in image data and identify the inspection target, based on the read data. Then, the inspection target information acquisition unit190may acquire information about the identified inspection target from the inspection target information recording unit180. Thus, even with a configuration using an RFID, the inspection assistance device101can acquire information about an inspection target.
