Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a continuation of U.S. application Ser. No. 16/142,268, filed Sep. 26, 2018, which claims priority pursuant to 35 U.S.C. § 119(a) to Japanese Patent Application Nos. 2017-184380, filed on Sep. 26, 2017, and 2018-172365, filed on Sep. 14, 2018 in the Japan Patent Office, the disclosure of each is incorporated by reference herein in its entirety. 
    
    
     BACKGROUND 
     Technical Field 
     This disclosure relates to an information processing apparatus, a system of assessing a structural object, and a method of assessing a structural object, and a non-transitory computer readable storage medium. 
     Background Art 
     Structural objects such as tunnels are covered with lining such as concrete. When concrete properties change over time, cracks or the like can occur. If the aged concrete of a tunnel is not maintained properly, concrete pieces might peel off from a wall of the tunnel, causing damage to vehicles and people on a road. Therefore, under the regulation and instructions of national and local government offices that monitor tunnels, inspection contractors or firms conduct periodic inspections of the tunnels, and reports inspection results of the tunnels to the government offices. The inspection contractors are required to submit inspection reports using a given document format regulated by the national and local governments in some countries. 
     Hereinafter, a description is given of conventional procedure of acquiring and handling data performed by an inspection contractor with reference to  FIG. 37 .  FIG. 37  illustrates a scheme of conventional inspection processing performed by the inspection contractor. 
     When the inspection contractor inspects a tunnel, an inspector takes notes of observed conditions of the tunnel on a field inspection book, captures images of changed-portions of the tunnel as changed-portion photographs, and then creates a final inspection report, to be submitted to the national and local government offices, describing tunnel properties (e.g., name, location, length, age) using a tunnel ledger obtained from the government offices. The final inspection report includes, for example, an observed inspection findings chart, a photograph-captured position chart, a photograph ledger, and a tunnel inspection result summary table, as illustrated in  FIG. 37 , in which the observed inspection findings chart includes the photograph-captured position chart. The inspection findings indicate any kind of findings observed on the tunnel surface, such as potential or imminent abnormalities (e.g., initial defects, aging defects, damages, deformations) that may cause problems, and non-abnormalities portions (e.g., stains) that may not cause problems. 
     The final inspection report can be created using conventional procedure as illustrated in  FIG. 37 . (1) The observed inspection findings chart represents drawings of inspection findings (e.g., cracks) observed at portions during the inspection. When the inspection contractor creates the observed inspection findings chart, the inspection contractor refers to various field inspection records, such as the field inspection book, the observed-inspection findings photographs, and the tunnel ledger to draw lines representing the inspection findings (e.g., cracks), and input a width of the lines, such as crack lines using a computer-aided design (CAD) program. 
     (2) The photograph ledger includes evaluation (assessment) results of the observed-inspection findings, such as cracks, associated with the observed-inspection findings photographs. The inspection contractor manually attaches the observed-inspection findings photographs on the photograph ledger, and inputs diagnosis information including the evaluation results by referring to detail information of the inspection findings recorded on the field inspection book during the inspection. Further, to clarify which portion of the tunnel corresponds to the observed-inspection findings photograph attached to the photograph ledger, the observed inspection findings chart is added with an identification number of the observed-inspection findings photograph attached to the photograph ledger. 
     (3) The tunnel inspection result summary table includes various information of the tunnel, such as tunnel properties (e.g., tunnel length) and the diagnosis information including the evaluation results. Specifically, the inspection contractor inputs the tunnel properties (e.g., tunnel length) in the tunnel inspection result summary table based on the tunnel ledger, and the diagnosis information including the evaluation results of the observed inspection findings based on the field inspection book. 
     (4) In order to associate the inspection findings-observed portions related to the evaluation results and the observed-inspection findings photograph attached to the photograph ledger, the inspection contractor inputs an identification number associated with the observed-inspection findings photograph attached to the photograph ledger on the tunnel inspection result summary table. 
     When creating the final inspection report including various inspection records such as the observed inspection findings chart, the photograph-captured position chart, the photograph ledger, and the tunnel inspection result summary table, the inspection contractor manually selects the detail information of inspection findings and the observed-inspection findings photographs that correspond to positions in the tunnel from a large number of the detail information of inspection findings recorded in the field inspection book and a large number of the observed-inspection findings photographs, in which the inspection contractor might make mistakes in the final inspection report, which might be caused by manual operation of creating the final inspection report. Further, the final inspection report is required to include a common description, such as diagnosis information or the like among various inspection records (e.g., the observed inspection findings chart, the photograph-captured position chart, the photograph ledger, and the tunnel inspection result summary table), and identification numbers to link various inspection records (e.g., the observed inspection findings chart, the photograph-captured position chart, and the photograph ledger) with each other. Therefore, even if only one part of the final inspection report is to be modified or corrected due to some reasons, each document of various inspection records included in the final inspection report is required to be modified or corrected, causing a greater effort and a longer time to create the final inspection report including the diagnosis information of the structural object such as the tunnel.

It should be noted that although such terms as first, second, etc. may be used herein to describe various elements, components, regions, layers and/or units, it should be understood that such elements, components, regions, layers and/or units are not limited thereby because such terms are relative, that is, used only to distinguish one element, component, region, layer or unit from another region, layer or unit. Thus, for example, a first element, component, region, layer or unit discussed below could be termed a second element, component, region, layer or unit without departing from the teachings of the present inventions. 
     In addition, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present inventions. Thus, for example, as used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Moreover, the terms “includes” and/or “including”, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     Hereinafter, a description is given of a diagnosis or assessment system according to an embodiment with reference to the drawings. 
     System Configuration: 
     Hereinafter, a description is given of an example of a system configuration of the diagnosis system  1  with reference to  FIG. 1 .  FIG. 1  is a schematic diagram of a diagnosis system  1  of the embodiment. In this description, the diagnosis includes any act or process of identifying the cause or nature of a condition, situation, or potential problem (such as abnormality) of an object such as structural object (e.g., tunnel). The examples of act or process of diagnosis include investigation, analysis, assessment (evaluation), etc. For example, assessment is any act or process of determining the condition, situation, or problem of the object, which is a target for diagnosis. In this description, the diagnosis system  1  can be also referred to as the assessment system. Further, in this description, for simplicity, the terms of “diagnosis” and “assessment” are interchangeably used. 
     As illustrated in  FIG. 1 , the diagnosis system  1  includes, for example, a diagnosis processing terminal  3 , and a diagnosis management server  5  connected via a communication network  100  wirelessly or by wire. In this description, the diagnosis processing terminal  3  and the diagnosis management server  5  are examples of information processing apparatuses or terminals used for processing data and information related to the structural object (e.g., tunnel). 
     The diagnosis processing terminal  3  and the diagnosis management server  5  included in the diagnosis system  1  can communicate with each other via the communication network  100 . The communication network  100  is constructed using a network, such as the Internet, a mobile communication network, a local area network (LAN), or the like. The communication network  100  can employ not only a wired communication network but also a wireless communication network such as 3rd generation (3G), worldwide interoperability for microwave access (WiMAX), and long term evolution (LTE). Further, the diagnosis processing terminal  3  can be configured to communicate using short-range communication technology such as near field communication (NFC: registered trademark). 
     As illustrated in  FIG. 1 , the inspector riding on the inspection vehicle  7  inspects the tunnel  8  by marking inspection findings (e.g., cracks) with a special chalk on a surface of the tunnel  8 , and records a width of each crack in a field inspection book. While inspecting the tunnel  8 , the inspector records detail information of inspection findings indicating the status or condition of the inspection findings and evaluation results of the inspection findings in the field inspection book. Further, an assistant standing near the inspection vehicle  7  can write the detail information of inspection findings spoken by the inspector in the field inspection book, and take pictures of the tunnel  8  in some cases. The inspection findings means any kind of findings observed on the tunnel surface, such as potential or imminent abnormalities (e.g., initial defects, aging defects, damages, deformations) that may cause problems, and non-abnormalities portions (e.g., stains) that may not cause problems. 
     Further, the inspector can put on a helmet put equipped with a small microphone and a small camera, in which comments made by the inspector can be recorded with the small microphone and target portions can be photographed with the small camera. In this case, the recorded voice information can be recognized by a voice recognition device and digitized as data, and the digitized data can be automatically recorded in an electronic recording device used as the field inspection book, such as a tablet personal computer (PC) or the like, together with the images photographed using the small camera. 
     Then, a vehicle  9  equipped with a camera unit (image capture device) travels from the entrance to the exit of the tunnel  8 , while capturing images of the inner surface of the tunnel  8  from an entry to an exit of the tunnel  8  to acquire images of the inner surface of the tunnel  8 , which is to be described later with reference to  FIG. 4 . Hereinafter, images of the captured inner surface of the tunnel  8  are collectively referred to as development-view image  201  of the tunnel, which corresponds to a panoramic image combining a plurality of images of a plurality of spans (formworks) of the tunnel  8 . The development-view image  201  is generated by performing image processing on a plurality of mages of the inner surface of the tunnel  8  captured by the camera unit. Since the development-view image  201  includes portions marked with the special chalk by the inspector, the user of the diagnosis processing terminal  3  can easily confirm positions and shapes of the inspection findings by checking the development-view image  201  after the inspection at the field. The development-view image  201  can be also be referred to as the image data of tunnel, which is an example of image data of the structural object generated using given image processing. 
     In addition to the camera unit, the vehicle  9  also includes a first range sensor for measuring a travel distance of the vehicle  9 , a second range sensor for measuring a distance between the vehicle  9  and the inner surface of the tunnel  8 , a gyro sensor for detecting an angle (posture) and an angular velocity (or angular acceleration) of the vehicle  9 . The second ranging sensor is, for example, a time-of-flight (TOF) sensor or a light detection and ranging (LIDAR) sensor. The development-view image  201  obtained by the camera unit of the vehicle  9 , and each detection data obtained from each sensor disposed in the vehicle  9  (e.g., first and second ranging sensors, gyro sensor) are transmitted to the diagnosis management server  5  via the diagnosis processing terminal  3 , and are managed by the diagnosis management server  5 . Alternatively, the development-view image  201  and the detection data can be directly transmitted to the diagnosis management server  5 , or any storage device on a cloud that is accessible from the diagnosis management server  5 . 
     In some regions, such as European continent and America, vehicle drivers keep to the right side of the road, so an image of the structural object (e.g., tunnel wall) on the right side of the vehicle in the traveling direction is captured and measured with the camera unit. In another region, such as United Kingdom and Japan, vehicle drivers keep to the left side of the road, so an image of the structural object (e.g., tunnel wall) on the left side of the vehicle in the traveling direction is captured and measured with the camera unit. 
     The diagnosis processing terminal  3  is a computer used for receiving an input of various data, such as diagnosis target image, diagnosis region, and diagnosis information, to be described later. A user (e.g., operator) uses the diagnosis processing terminal  3  to input various data related to the structural object (e.g., tunnel), such as the development-view image  201 , generated by capturing the images of tunnel  8  from an entrance to an exit of the tunnel  8  and processing, and the detail information of inspection findings recorded on the field inspection book by the inspector or assistant for the tunnel  8 , and the detection data obtained by each sensor for the tunnel  8 . In this description, the tunnel  8  is described as an example of the structural object, but the structural object is not limited thereto. In another example, the data related to the structural object can be transmitted to another device such as the diagnosis management server  5 , and then transferred from another device to the diagnosis processing terminal  3 . 
     Further, the user of the diagnosis processing terminal  3  inputs data of the tunnel ledger obtained from the government office in the diagnosis processing terminal  3 . The tunnel ledger includes data of the tunnel properties such as the length and height of the tunnel. Alternatively, the diagnosis processing terminal  3  can receive the data of the tunnel ledger from a server of the government office. In this case, the diagnosis processing terminal  3  can be used as an input device to which data is input. 
     Further, a browser is installed in the diagnosis processing terminal  3 . The diagnosis processing terminal  3  can display the development-view image  201  transmitted from the diagnosis management server  5  using the browser. 
     Further, the user of the diagnosis processing terminal  3  performs a drawing of an image of given pattern, such as line or the like, over the observed inspection findings (e.g., crack) on the development-view image  201 . The drawn image corresponding to the observed inspection findings is stored, for example, in a memory of the diagnosis management server  5  in association with coordinates indicating a position of the drawn image, and a numerical value (e.g., width) of the drawn image. 
     The user of the diagnosis processing terminal  3  downloads data of a submission document including, for example, the observed inspection findings chart created by drawing the observed inspection findings, from the diagnosis management server  5 , and submits the printed submission document or the electronic data of the submission document (i.e., non-printed data) to the government office or the like. For example, the communication unit  51  of the diagnosis management server  5  transmits the data of the submission document including, for example, the observed inspection findings chart created by drawing of the observed inspection findings, to the diagnosis processing terminal  3  via the communication network  100 . As a result, the communication unit  31  of the diagnosis processing terminal  3  receives the data of the submission document. 
     In one example, the communication unit  31  of the diagnosis processing terminal  3  transmits the data of the submission document to a printing apparatus, and after printing the submission document, the user of the diagnosis processing terminal  3  submits the printed paper to the government office or the like. 
     Alternatively, the communication unit  31  of the diagnosis processing terminal  3  transmits the data of the submitted document to the government office or the like via the communication network  100 . 
     Alternatively, the communication unit  31  of the diagnosis processing terminal  3  stores the data of the submission document on a recording medium such as DVD-R, and then, the user of the diagnosis processing terminal  3  submits the recording media to the government office or the like. 
     The communication unit  31  and the storing/reading unit  39  can be used as an output unit when submitting the submission document (electronic data or printed paper) to the government office or the like. In this case, the diagnosis processing terminal  3  can be used as an output device from which data is output. 
     Further, in order to ensure credibility or authenticity of the submission document such as electronic data and printed sheets submitted to the national government office or the like, it is preferable to apply tamper-proof processing to the submission document. 
     The diagnosis management server  5  manages various data, such as the development-view image  201 , detail information of the inspection findings, and the tunnel ledger. Further, the diagnosis management server  5  manages data obtained by drawing an image such as line or the like over the observed inspection findings (e.g., crack) associated with coordinates indicating the position of the drawn image on the development-view image  201 , and the numerical value (e.g., width) of the drawn image.

     The communication unit  31 , implemented by the network I/F  309  and an instruction from the CPU  301  ( FIG. 2 ), transmits and receives various data or information to and from other terminals, devices, or systems via the communication network  100 . 
     The reception unit  32  is typically implemented by an instruction from the CPU  301  ( FIG. 2 ). When the reception unit  32  receives signals from the keyboard  311  and/or the mouse  312  operated by a user, the reception unit  32  receives various operations performed by a user. 
     The drawing unit  33 , implemented by an instruction from the CPU  301  ( FIG. 2 ), draws a pattern, such as a line or an area (e.g., rectangular shape), on an image displayed on the display  308 . 
     The display control unit  34 , implemented by an instruction from the CPU  301  ( FIG. 2 ), causes the display  308  to display various images and screens. 
     The determination unit  35 , implemented by an instruction from the CPU  301  ( FIG. 2 ), performs various determinations to be described later. 
     The storing/reading unit  39 , implemented by an instruction from the CPU  301  and the HDD  305 , the media I/F  307 , and the CD-RW drive  314  ( FIG. 2 ), stores various data in the storage unit  3000 , the recording medium  306 , and the CD-RW  313 , and reads various data from the storage unit  3000 , the recording medium  306 , and the CD-RW  313 . 
     Functional Configuration of Diagnosis Management Server: 
     As illustrated in  FIG. 3 , the diagnosis management server  5  includes, for example, a communication unit  51 , a generation unit  53 , a determination unit  55 , and a storing/reading unit  59 . Each of these units indicates a function or functional unit implemented by operating any of the hardware components illustrated in  FIG. 2  under an instruction from the CPU  501  executing programs loaded to the RAM  503  from the HD  504 . The diagnosis management server  5  further includes a storage unit  5000 , implemented by the HD  504  ( FIG. 2 ). 
     Development-View Image and Coordinate Data: 
       FIG. 4  is a schematic diagram indicating a relationship of the development-view image  201  and coordinate data  201   c . As illustrated in  FIG. 3 , the storage unit  5000  stores various data, such as detail information of inspection findings, the development-view image  201 , data of each sensor such as a range sensor, and data of a tunnel ledger. The coordinate data  201   c  is data generated by the generation unit  53  after the communication unit  51  of the diagnosis management server  5  acquires the development-view image  201  and the detection data from the diagnosis processing terminal  3 . The generation method of the coordinate data  201   c  will be described later. 
     When the development-view image  201  is output from the camera unit of the vehicle  9 , the development-view image  201  is the image data alone without any information regarding a positional relationship between the development-view image  201  and the actual tunnel. If the positional relationship between the development-view image  201  and the actual tunnel is not accurately defined, it would take too much time and effort for the user to identify the location of the inspection findings (e.g., cracks, any defects), found or observed during the inspection, on the development-view image  201 . Therefore, in order to accurately define the positional relationship between the development-view image  201  and the actual tunnel, the coordinate data corresponding to the development-view image  201  is generated. 
     As illustrated in in  FIG. 4 , the tunnel is configured with a plurality of spans (formworks) made of certain material such as concrete, in which each span sequentially represents a first span, a second span, a third span, and so on from an entrance to an exit of an actual tunnel. The span indicates each segment having a given width (e.g., 10 meters), which is segmented from the entrance to the exit of the tunnel  8 .  FIG. 4  illustrates an example of the development-view image  201  composed of images of multiple spans. The span number is specified in the tunnel ledger managed by the government office. 
     Further, as illustrated in in  FIG. 4 , the coordinate data is set for the plurality of spans, in which a span number for the coordinate data is set from the left to the right, such that the first span is indicated by a span number “S 001 ,” and the second span is indicated by a span number “S 002 ,” and so on. In addition, coordinates (xn, ym) are used to indicate a specific position in each span. For example, even if one point in one span and another point in another span (i.e., any two points) in the coordinate data are represented by the same coordinates, since the spans are different, the coordinates of one point in one span and the coordinates of another point in another span indicate different positions in the tunnel. Accordingly, with the coordinate data defining the coordinates (xn, ym) of specific positions in the specific span number, the positional relationship between the development-view image  201  and the actual tunnel can be accurately defined, such that a specific location of the inspection finding (e.g., defect) marked on the actual tunnel can be identified using the coordinate system of the development-view image  201 . As above described, the development-view image  201  are associated with coordinate data of the tunnel  8 . In case of a tunnel without spans, a specific position in the development-view image is identified using a position coordinate alone without using the span number such as “S 001 .” 
     Diagnosis Information Management Table: 
       FIG. 5  is an example of a diagnosis information management table. The storage unit  5000  stores and manages a diagnosis information management database (DB)  5001  ( FIG. 3 ) including the diagnosis information management table of  FIG. 5 . The coordinate data  201   c  ( FIG. 4 ) is generated by the diagnosis management server  5  as described above. The diagnosis processing terminal  3  receives a user operation to draw an image such as a line or the like over the observed inspection findings, such as cracks, displayed on the development-view image  201 . With the coordinate data  201   c  and the drawing made by the user, the specific position of the observed inspection findings on the development-view image  201  is identified. Specifically, the diagnosis management server  5  uses the diagnosis information management table ( FIG. 5 ) to manage the coordinates of the identified observed inspection findings portion, indicating a position of the identified observed inspection findings portion. 
     As illustrated in  FIG. 5 , the diagnosis information management table stores various items, such as a diagnosis region number, a span number (formwork number), coordinates within a span of a diagnosis region, a height and width of a diagnosis region, a photograph number, a type of observed inspection findings and abnormality (potential abnormalities), an evaluation result, and detail information of inspection findings, which are associated with each other. In this description, the diagnosis information may be also referred to as the assessment-related information or assessment information. 
     The diagnosis region number is identification information identifying a group including a diagnosis region to be described later. The span number (formwork number) is a number assigned to each span of the tunnel  8 . The span number is specified in the tunnel ledger managed by the government office. The span number corresponds to a specific span number in the coordinate data  201   c  illustrated in  FIG. 4 , and is a value indicating the specific span number of the tunnel  8 . 
     The coordinates within the span related to the diagnosis region indicate specific position coordinates in the coordinate data  201   c  illustrated in  FIG. 4 , and indicate the position coordinates of a specific point (e.g., start point) of the diagnosis region in a specific span that is counted, for example, from the origin point of the specific span. 
     The height and width of the diagnosis region indicate the height and the width of a specific diagnosis region with respect to the origin point of the specific span related to the specific diagnosis region. The height and width of the diagnosis region indicate values identifying the entire specific diagnosis region. 
     The photograph number is identification information identifying a photograph attached to the photograph ledger. 
     The type of observed inspection findings and abnormality indicate a type of inspection findings and abnormality at the inspection object and portion inspected by the inspector. 
     The evaluation result indicates an evaluation of the diagnosis target inspected by the inspector. Typically, the conditions of the diagnosis target are ranked using the evaluation levels of “S, A, B, and C,” in which “S” is the worst condition, and the condition becomes less severe in the order of “S, A, B, and C.” The evaluation result may be also referred to as the assessment result in this description. 
     The detail information of inspection findings is contents of information of inspection findings recorded by the inspector and/or the assistant ( FIG. 1 ). 
     Diagnosis Target Element Management Table: 
       FIG. 6  illustrates an example of a diagnosis target element management table. The storage unit  5000  stores and manages a diagnosis target element management DB  5002  ( FIG. 3 ) including the diagnosis target element management table of  FIG. 6 . As illustrated in  FIG. 6 , the diagnosis target element management table stores various items, such as a diagnosis region number, a span number (formwork number), an element number, coordinates of a start point of a diagnosis target element image, coordinates of an end point of a diagnosis target element image, and a width of a diagnosis target element (mm) in association with each other. 
     The diagnosis region number and the span number (formwork number) are the same as those in the diagnosis information management table ( FIG. 5 ). The diagnosis information management table ( FIG. 5 ) and the diagnosis target element management table ( FIG. 6 ) are associated with each other using the diagnosis region number and the span number (formwork number). 
     The element number is identification information identifying a diagnosis target element image, which is the element of the diagnosis target image. 
     The coordinates of the start point of the diagnosis target element image indicate the coordinates of the start point when the diagnosis target element image is drawn in a specific span in the development-view image  201 . For example, in an example case of  FIG. 25 , coordinates of a start point “p 21 ” indicate the start point of a first diagnosis target element image “e 21 .” 
     The coordinates of the end point of the diagnosis target element image indicate the coordinates of the end point when the diagnosis target element image is drawn in a specific span in the development-view image  201 . For example, in an example case of  FIG. 25 , coordinates of an end point “p 22 ” indicate the end point of the first diagnosis target element image “e 21 .” Further, each of the coordinates of the start point and the coordinates of the end point of the diagnosis target element image indicates a specific position coordinate in the coordinate data  201   c  illustrated in  FIG. 4 . 
     The width (mm) of the diagnosis target element represents a width of something, such as cracks when the diagnosis target element is cracks. For example, an example case of  FIG. 25 , a value is input to a width input screen “ws 1 ” by a user. When the user inputs a numerical value in the width input screen “ws 1 ,” the reception unit  32  receives the input numerical value, and then the display control unit  34  displays the input numerical value (e.g., “0.5”) as illustrated in  FIG. 26 . 
     Hereinafter, a description is given of a functional configuration of the diagnosis management server  5 . 
     In the following description, each functional unit of the diagnosis management server  5  is described in relation with any of the components illustrated in  FIG. 2  used for implementing each functional unit of the diagnosis management server  5 . 
     The communication unit  51  of the diagnosis management server  5  ( FIG. 3 ), implemented by an instruction of the CPU  501  ( FIG. 2 ) and the network I/F  509  ( FIG. 2 ), transmits and receives various data or information to and from other devices or terminals via the communication network  100 . 
     The generation unit  53 , implemented by an instruction from the CPU  501  ( FIG. 2 ), generates the coordinate data  201   c  ( FIG. 4 ) based on the development-view image  201  and the detection data of sensors, such as the ranging sensor, acquired from the diagnosis processing terminal  3  by the communication unit  51  of the diagnosis management server  5 . 
     Specifically, the generation unit  53  generates the coordinate data  201   c  for the development-view image  201  using the detection data acquired from the sensors (e.g., first and second ranging sensors, gyro sensors) installed in the vehicle  9  via the diagnosis processing apparatus  3  as described above. 
     While the vehicle  9  is capturing images of a tunnel inner surface while traveling through the tunnel  8 , it is practically difficult for the vehicle  9  to travel at a constant speed in the tunnel  8 , and to maintain a constant distance between the vehicle  9  and the tunnel inner surface. Further, the vehicle  9  is often tilted at an angle due to dents on the road surface in the tunnel  8 . 
     Therefore, the generation unit  53  uses the detection data of each sensor to generate the coordinate data for the development-view image  201  while correcting the coordinate data. In a case of  FIG. 4 , when the position of the left upper corner of the span S 001  in the coordinate data  201   c  and the upper left corner of the first span of the development-view image  201  are matched, the origin point is determined, with which the generation unit  53  can generate the coordinate data for the development-view image  201  based on the set origin point. 
     Further, the diagnosis management server  5  can set the origin point according to a user preference, such as an input from an administrator, or can automatically set the origin point at the generation unit  53 . When the origin point is set automatically, the luminance value of the photographed image rapidly changes at the entrance of the tunnel (i.e., a boundary between the outside and inside of the tunnel), in which the generation unit  53  can easily identify the entrance of the tunnel from the photographed image. 
     Further, the generation unit  53  generates data of a submission document (e.g., observed inspection findings chart, photograph ledger, tunnel inspection result summary table) to be submitted to the government office based on various data managed by the diagnosis information management DB  5001  and a diagnosis target element management DB  5002 . 
     The determination unit  55 , implemented by an instruction from the CPU  501  ( FIG. 2 ), performs a determination process when the generation unit  53  is to generate data of the submission document. 
     The storing/reading unit  59 , implemented by an instruction from the CPU  501  and the HDD  505  ( FIG. 2 ), stores various data in the storage unit  5000 , and reads out various data stored in the storage unit  5000 . 
     Processing and Operation: 
     Hereinafter, a description is given of the processing and operation of the embodiment with reference to  FIGS. 7 to 35 .  FIG. 7  is an example of a sequence diagram illustrating a process of updating data including the development-view image.  FIG. 8  is an example of a sequence diagram illustrating a process of generating data of a submission document.  FIGS. 9A, 9B, 9C, and 9D  illustrate a scheme of creating a submission document according to one embodiment. 
     At first, as illustrated in  FIG. 9A , the diagnosis processing terminal  3  is input with data of a tunnel ledger acquired from the government office in accordance with a user operation (step S 1 ). Hereinafter, the data input by the user using the diagnosis processing terminal  3  is referred to as “field inspection data of the target tunnel.” 
     Further, the diagnosis processing terminal  3  is input with the development-view image, data of the detail information of inspection findings, and detection data of one or more sensors (e.g., range sensor), respectively obtained from the vehicle  9  in accordance with the user operation (step S 2 ). 
     The communication unit  31  of the diagnosis processing terminal  3  uploads the data of the tunnel ledger, input in step S 1 , and each data (e.g., the development-view image  201 , data of detail information of inspection findings, and detection data of sensors such as a range sensor) input in step S 2 , to the diagnosis management server  5  (step S 3 ). As a result, the communication unit  51  of the diagnosis management server  5  receives the data, such as the data of the tunnel ledger. 
     The diagnosis management server  5  generates the coordinate data  201   c  ( FIG. 4 ) based on the development-view image  201  and the detection data. 
     The storing/reading unit  59  stores the data, such as the data of the tunnel ledger, received in step S 3 , and the coordinate data  201   c , generated in step S 4 , in the storage unit  5000  in association with one another (step S 5 ). 
     At any time when the user inputs the diagnosis target image, as illustrated in  FIG. 8 , the communication unit  31  of the diagnosis processing terminal  3  transmits a request for the field inspection data of the target tunnel, such as the tunnel ledger or the like, to the diagnosis management server  5  in accordance with the user operation (step S 11 ). As a result, the communication unit  51  of the diagnosis management server  5  receives the request for the data, such as a tunnel ledger. 
     Then, in the diagnosis management server  5 , the storing/reading unit  59  reads the field inspection data of the target tunnel, such as data of the tunnel ledger or the like, stored in the storage unit  5000  in step S 5  (step S 12 ). 
     The communication unit  51  transmits the field inspection data of the target tunnel, such as the tunnel ledger, read in step S 12 , to the diagnosis processing terminal  3  (step S 13 ). As a result, the development-view image  201  is displayed at the diagnosis processing terminal  3  using the browser. 
     As illustrated in  FIG. 9A , in accordance with the user operation, the diagnosis processing terminal  3  performs a process of drawing a diagnosis target image (including diagnosis target element image) on a part of the development-view image  201  (hereinafter, partial development-view image  202 ), and inputting diagnosis information (step S 14 ). The process of step S 14  will be described in detail later. 
     The communication unit  31  transmits a request for creating a submission document to be submitted to the government office or the like to the diagnosis management server  5 , together with the data of the drawn diagnosis target element image, and the data of the input diagnosis information (step S 15 ). As a result, the communication unit  51  of the diagnosis management server  5  receives the request for creating the submission document with the data of the diagnosis target element image and the data of the diagnosis information. 
     Then, in the diagnosis management server  5 , the storing/reading unit  59  stores the data of the diagnosis information and the data of the diagnosis target element image, respectively, in the diagnosis information management DB  5001  and the diagnosis target element management DB  5002  (step S 16 ). 
     Further, in order to create the submission document, the storing/reading unit  59  reads the data of diagnosis information and the data of the diagnosis target element image, respectively from the diagnosis information management DB  5001  and the diagnosis target element management DB  5002 , and also reads the data, such as the tunnel ledger or the like, from the storage unit  5000  (step S 17 ). 
     Then, the generation unit  53  of the diagnosis management server  5  generates the data of the submission document (e.g., observed inspection findings chart, photograph ledger, tunnel inspection result summary table), illustrated in  FIG. 9 , using the data of diagnosis information, the data of the diagnosis target element image, and the data of tunnel ledger or the like (step S 18 ). 
     The communication unit  51  transmits the data of the submission document to the diagnosis processing terminal  3  (step S 19 ). As a result, the communication unit  31  of the diagnosis processing terminal  3  receives the data of the submission document. 
     As illustrated in  FIG. 9A , the diagnosis processing terminal  3  prints out the data of the submission document to be submitted to the government office or the like (step S 20 ). 
     As illustrated in  FIGS. 9B, 9C, and 9D , the submission document includes, for example, the tunnel inspection result summary table ( FIG. 9B ), the observed inspection findings chart ( FIG. 9C ), and the photograph ledger ( FIG. 9D ). By performing the above described processing, the inspection contractor can submit the data of the submission document to the government office using printed sheets. Alternatively, if the government rule, such as the national government rule, allows the submission of the data of the submission document to the government office using electronic data alone, the inspection contractor can submit the electronic data of the submission document to the government office without printing the data of the submission document. 
     Further, the submission document maybe submitted to the government office from one entity that has created the submission document, or the submission document created by one entity is transferred to another entity, and then submitted to the government office from another entity.
 
Drawing and Inputting of Diagnosis Information:
 
     Hereinafter, a description is given of the detail of step S 14  with reference to  FIGS. 10, 14 and 15 .  FIG. 10  is an example of a flowchart illustrating the steps of the drawing of the image and inputting of the diagnosis information.  FIG. 14  is an example of a home screen SC 1 .  FIG. 15  is an example of a diagnosis position input screen SC 2  when a first input mode of a diagnosis target image (i.e., drawing of area) is selected. 
     Referring to  FIG. 10 , at first, when a user operates the diagnosis processing terminal  3 , the display control unit  34  displays the home screen SC 1  ( FIG. 14 ) on the display  308  (step S 21 ). 
     As illustrated in  FIG. 14 , the home screen SC 1  displays a development-view image  201  on the center of the home screen SC 1 . Further, as illustrated in  FIG. 14 , the home screen SC 1  displays a total image screen SC 10  showing an entire image of the development-view image  201  on the right upper corner of the home screen SC 1 . Further, as illustrated in  FIG. 14 , a plurality of selection buttons “b 1 ” to “b 6 ” is displayed on the upper left corner of the home screen SC 1 . The selection button “b 1 ” is used for selecting a first input mode for inputting an area of the diagnosis target image (i.e., drawing of area). The selection button “b 2 ” is used for selecting a second input mode for inputting lines of the diagnosis target image (i.e., drawing of line pattern). The selection button “b 3 ” is used for selecting a third input mode for inputting the diagnosis region. When selected, the home button “b 4 ” is used for returning to the home screen SC 1 . The reduction button “b 5 ” is used for reducing a display size of the development-view image  201 . The enlargement button “b 6 ” is used for enlarging a display size of the development-view image  201 . 
     Further, as illustrated in  FIG. 14 , “RELOAD” button “b 11 ” is displayed at the lower center portion of the home screen SC 1 . The “RELOAD” button b 11  is used for displaying a pull-down menu that lists data of the diagnosis region already uploaded to the diagnosis management server  5 . Similarly, as illustrated in  FIG. 14 , “SAVE” button “b 12 ” is displayed at the lower center portion of the home screen SC 1 . The “SAVE” button “b 12 ” is used for collectively transmitting data of the diagnosis region, temporarily stored in the diagnosis processing terminal  3 , to the diagnosis management server  5  to save the data of a diagnosis region in the diagnosis management server  5 . Further, a save list  210  is also displayed at the lower center portion of the home screen SC 1 . The save list  210  is used for displaying names of data of diagnosis regions downloaded from the diagnosis management server  5 , and names of data of diagnosis regions temporarily stored in the diagnosis processing terminal  3 . When the user selects the save list  210  using the pointer “po,” the display control unit  34  displays the diagnosis position input screen SC 2  showing the corresponding diagnosis region. 
     Further, as illustrated in  FIG. 14 , a layer list LL 1  is displayed on the right side of the home screen SC 1 . The layer list LL 1  lists types of inspection findings, such as defects. For example, the layer list LL 1  displays the types of defects, such as a crack, a water leakage, and a calcification. When a check box of the layer list LL 1  is checked, a layer of the checked defect is displayed on the development-view image  201 . Further, as illustrated in  FIG. 14 , “LAYER” button “b 13 ” is displayed at the right lower side of the home screen SC 1 . The “LAYER” button “b 13 ” is used for displaying the layer list LL 1  on a top layer. 
     When a user operates the mouse  312  to select a specific span, to be input with the drawing and diagnosis information, using the pointer “po” on the home screen SC 1 , the display control unit  34  displays the diagnosis position input screen SC 2  on the display  308  as illustrated in  FIG. 15  (step S 22 ). The diagnosis position input screen SC 2  displays a partial development-view image  202  corresponding to the selected span of the development-view image  201 . Further, as illustrated in  FIG. 15 , a viewing direction switching button “bc 1 ” is displayed on the right lower corner of the diagnosis position input screen SC 2 . The viewing direction switching button “bc 1 ” is used for switching the viewing direction of the development-view image  201 . The switching of the viewing direction will be described later with reference to  FIGS. 34 and 35 . 
     When the user selects any one of the selection buttons “b 1 ,” “b 2 ,” and “b 3 ” using the pointer “po,” the reception unit  32  receives the selection of the input mode (step S 23 ). 
     Then, when the user performs the drawing of image and the inputting of diagnosis information in accordance with the input mode, the drawing of image and the inputting of diagnosis information are processed by the diagnosis processing terminal  3  (step S 24 ). The detail of step S 24  will be described later for each input mode. 
     Then, when the reception unit  32  receives an operation of the mouse  312  and the like performed by the user, the storing/reading unit  39  temporarily stores the data of the diagnosis region generated by performing the drawing of image and the inputting of diagnosis information to the storage unit  3000  (step S 25 ). The drawn image data and the input diagnosis information are to be transmitted to the diagnosis management server  5  from the diagnosis processing terminal  3  in step S 15  described above. 
     Input Mode of Diagnosis Target Image (Drawing of Area): 
     Hereinafter, a description is given of the detail of step S 24  ( FIG. 10 ) when the first input mode for inputting an area of the diagnosis target image (i.e., drawing of an area) is selected with reference to  FIGS. 11, and 15 to 22 . The first input mode for inputting an area of the diagnosis target image (i.e., drawing of an area) can be referred to as the first input mode of the diagnosis target image in this description. The first input mode of the diagnosis target image (i.e., drawing of an area) is used when the diagnosis target corresponds to inspection findings that can be identified as a certain area, such as calcification and water leakage. 
       FIG. 11  is an example of a flowchart illustrating processing of the first input mode of the diagnosis target image (i.e., drawing of an area).  FIG. 15  is an example of the diagnosis position input screen SC 2  when the first input mode of a diagnosis target image (i.e., drawing of an area) is selected.  FIGS. 16 to 21  are examples of screens when inputting the diagnosis target image (i.e., drawing of an area) on the diagnosis position input screen.  FIG. 22  is another example of the diagnosis position input screen. 
     At first, when a user selects the selection button “b 1 ” in step S 23  ( FIG. 10 ) using the pointer “po,” the display control unit  34  sets the first input mode of the diagnosis target image (i.e., drawing of an area) as illustrated in  FIG. 15 . 
     In this case, as illustrated in  FIG. 16 , when the user identifies a start point “p 11 ” of a first diagnosis target element image “e 11 ” using the pointer “po,” the reception unit  32  receives the input of the start point “p 11 ” of the first diagnosis target element image “e 11 ” (step S 101 ). 
     Then, the display control unit  34  displays an enter button “co 11 ” and a cancel button “ca 11 ” around the start point “p 11 ” (step S 102 ). The enter button “co 11 ” is used for entering the input of the diagnosis target image to confirm the input of the diagnosis target element image. The cancel button “ca 11 ” is used for cancelling the input of the identified start point “p 11 .” Further, other enter buttons and other cancel buttons can be respectively used in the same way as the enter button “co 11 ” and the cancel button “ca 11 ” in this description. 
     As illustrated in  FIG. 17 , when the user identifies an end point “p 12 ” of the diagnosis target element image e 11  using the pointer “po,” the reception unit  32  receives the input of the end point “p 12 ” of the first diagnosis target element image “e 11 ” (step S 103 ). 
     Then, the display control unit  34  displays the first diagnosis target element image “e 11 ” between the start point “p 11 ” and the end point “p 12 ,” and also displays an enter button “co 12 ” and a cancel button “ca 12 ” around the center of the first diagnosis target element image “e 11 ” (step S 104 ) as illustrated in  FIG. 17 . As described above, the user can draw the diagnosis target element image by identifying the start point and the end point of the diagnosis target element image. 
     The determination unit  35  determines whether the diagnosis target element image, displayed in step S 104 , includes a plurality of diagnosis target element images (step S 105 ). At this time, since only one diagnosis target element image is displayed as illustrated in  FIG. 17 , the determination unit  35  determines that the diagnosis target element image does not include the plurality of diagnosis target element images (step S 105 : NO), and the sequence proceeds to step S 106 . 
     When the determination unit  35  determines that the diagnosis target element image does not include the plurality of diagnosis target element images (step S 105 : NO), the determination unit  35  determines whether pressing of the enter button is received by the reception unit  32  (step S 106 ). If the determination unit  35  determines that the pressing of the enter button is received by the reception unit  32  (step S 106 : YES), the sequence proceeds to step S 110 , to be described later. On the other hand, if the determination unit  35  determines that the pressing of the enter button is not received by the reception unit  32  (step S 106 : NO), the sequence returns to step S 103 . 
     As illustrated in  FIG. 18 , when the user identifies an end point “p 13 ” of a second diagnosis target element image “e 12 ” using the pointer “po,” the reception unit  32  receives the input of an end point “p 13 ” of the second diagnosis target element image “e 12 .” Since the start point of the second diagnosis target element image  12  matches the end point “p 12 ” of the first diagnosis target element image “e 11 ,” the user can omit the identification of the start point of the second diagnosis target element image “e 12 .” 
     Then, in step S 104 , the display control unit  34  displays the second diagnosis target element image “e 12 ” between the start point (i.e., end point “p 12 ”) and the end point “p 13 ,” and also displays an enter button “co 13 ” and a cancel button “ca 13 ” between the first diagnosis target element image “e 11 ” and the second diagnosis target element image “e 12 ” as illustrated in  FIG. 18 . 
     Then, in step S 105 , the determination unit  35  determines whether the diagnosis target element image, displayed in step S 104 , includes a plurality of diagnosis target element images. At this time, since two diagnosis target element images (i.e., the first diagnosis target element image “e 11 ” and the second diagnosis target element image “e 12 ”) are displayed as illustrated in  FIG. 18 , the determination unit  35  determines that plurality of the diagnosis target element images is displayed (step S 105 : YES). 
     Then, the display control unit  34  automatically displays a third diagnosis target element image “e 13 ” (i.e., new diagnosis target element image) between the start point “p 11 ” of the first diagnosis target element image “e 11 ” and the end point “p 13 ” of the second diagnosis target element image “e 12 ” as illustrated in  FIG. 18  (step S 107 ), in which the third diagnosis target element image “e 13 ” is the latest diagnosis target element image. 
     Further, the display control unit  34  changes the display positions of the enter button and the cancel button (step S 108 ). Specifically, the display control unit  34  changes the enter button “co 12 ” and the cancel button “ca 12 ” illustrated in  FIG. 17  to the enter button “co 13 ” and the cancel button “ca 13 ” illustrated in  FIG. 18 . 
     Then, the determination unit  35  determines whether the pressing of the enter button is received by the reception unit  32  (step S 109 ). If the determination unit  35  determines that the pressing of the enter button is not received by the reception unit  32  (step S 109 : NO), the sequence returns to the above described step S 103 . 
     As illustrated in  FIG. 19 , when the user identifies an end point “p 14 ” of the third diagnosis target element image “e 13 ” using the pointer “po,” the reception unit  32  receives the input of the end point “p 14 ” of the third diagnosis target element image “e 13 .” Since the start point of the third diagnosis target element image “e 13 ” matches the end point “p 13 ” of the second diagnosis target element image “e 12 ,” the user can omit the identification of the start point of the third diagnosis target element image “e 13 .” 
     Then, in step S 104 , the display control unit  34  displays the third diagnosis target element image “e 13 ” between the start point (i.e., end point “p 13 ”) and the end point “p 14 ,” and also displays an enter button “co 14 ” and a cancel button “ca 14 ” between the first diagnosis target element image “e 11 , the second diagnosis target element image “e 12 ,” and the third diagnosis target element image “e 13 .” 
     Then, in step S 105 , the determination unit  35  determines whether the diagnosis target element image, displayed in step S 104 , includes the plurality of the diagnosis target element images. At this time, since three diagnosis target element images are displayed as illustrated in  FIG. 19 , the determination unit  35  determines that the diagnosis target element image, displayed in step S 104 , includes the plurality of the diagnosis target element images (step S 105 : YES). 
     Then, in step S 107 , the display control unit  34  automatically displays a fourth diagnosis target element image “e 14 ” (i.e., new diagnosis target element image) between the start point “p 11 ” of the first diagnosis target element image “e 11 ” and the end point “p 14 ” of the third diagnosis target element image “e 13 ” as illustrated in  FIG. 19 , in which the fourth diagnosis target element image “e 14 ” is the latest diagnosis target element image. 
     Further, in step S 108 , the display control unit  34  changes the display positions of the enter button and the cancel button. Specifically, the display control unit  34  changes the enter button “co 13 ” and the cancel button “ca 13 ” illustrated in  FIG. 18  to the enter button “co 14 ” and the cancel button “ca 14 ” illustrated in  FIG. 19 . 
     Then, as illustrated in  FIG. 20 , when the user presses the enter button “co 14 ” using the pointer “po,” the reception unit  32  receives the pressing, and the determination unit  35  determines that the pressing of the enter button is received by the reception unit  32  (step S 109 : YES). 
     Then, as illustrated in  FIG. 21 , the determination unit  35  confirms the diagnosis target image (i.e., drawing of area), and the display control unit  34  displays a confirmed diagnosis target image “dt 1 ” (step S 110 ). 
     Then, as illustrated in  FIG. 21 , the display control unit  34  displays a rectangular-shaped diagnosis region “da 1 ” including the diagnosis target image “dt 1 ,” and a diagnosis information input screen SC 3  (step S 111 ). In this case, in order to make the diagnosis information input screen SC 3  conspicuous, the display control unit  34  can apply a masking on a portion other than the diagnosis information input screen SC 3 . In this description, the diagnosis information input screen SC 3  may be referred to as the first input screen, and the diagnosis information input screen SC 3  and other similar screens can be also referred to as the input screen, the input section, or the input box depending on purposes of the screens, in which the size of screen may be set smaller than a size of the display  308 . 
     The user, such as the operator, uses the diagnosis information input screen SC 3  to input the diagnosis information by referring to the detail information of inspection findings recorded by the inspector or the assistant. As illustrated in  FIG. 21 , the diagnosis information input screen SC 3  displays, for example, a selection button to link with the previous or past diagnosis information, a first pull-down menu for selecting an inspection object, a second pull-down menu for selecting an inspection portion, a third pull-down menu for selecting a type of observed-inspection findings and abnormality, a first input field for inputting an evaluation result, and a second input field for inputting the detail information of inspection findings. 
     The link with the previous or past diagnosis information is used when adding a new diagnosis target image in the already confirmed diagnosis region. For example, the link with the previous or past diagnosis information can be used when water leakage is already confirmed as one diagnosis target image in one diagnosis region, and then crack is added as a new diagnosis image in the one diagnosis region including the water leakage. Further, as illustrated in  FIG. 21 , the diagnosis information input screen SC 3  displays “OK” button for confirming the input diagnosis information, and “CANCEL” button for canceling the input diagnosis information. The diagnosis information can be also referred to as the assessment information. 
     In this case, when the user selects and inputs the diagnosis information in the diagnosis information input screen SC 3  and presses the “OK” button, the reception unit  32  receives the selection and the input of the diagnosis information (step S 112 ). 
     Further, as illustrated in  FIG. 21 , the diagnosis information input screen SC 3  displays an input switching button “bm” for switching from the diagnosis information input screen SC 3  to a diagnosis information input screen SC 4  illustrated in  FIG. 22 . When the input switching button “bm” ( FIG. 21 ) is pressed, the display control unit  34  switches the diagnosis information input screen SC 3  to the diagnosis information input screen SC 4  ( FIG. 22 ). 
     The diagnosis information input screen SC 4  is used when one diagnosis region includes a plurality of diagnosis target images, and the diagnosis information is input for each one of the diagnosis target images. For example, when one diagnosis region includes three diagnosis target images (e.g. cracks, calcifications, water leaks), the diagnosis information input screen SC 4  is used to collectively manage the one diagnosis region including the three diagnosis target images. In this case, when data of the diagnosis information is uploaded from the diagnosis processing terminal  3  to the diagnosis management server  5  at a later time, the diagnosis management server  5  manages the three diagnosis target images (e.g., cracks, calcifications, and water leaks) included in the same diagnosis region having the diagnosis region number of “3” as illustrated in  FIG. 5 . 
     Similar to the diagnosis information input screen SC 3 , the diagnosis information input screen SC 4  displays “OK” button for confirming the input diagnosis information, and “CANCEL” button for canceling the input diagnosis information as illustrated in  FIG. 22 . Further, as illustrated in  FIG. 22 , the diagnosis information input screen SC 4  displays an input switching button “bs” for switching from the diagnosis information input screen SC 4  to the diagnosis information input screen SC 3  ( FIG. 21 ). When the input switching button “bs” ( FIG. 22 ) is pressed, the display control unit  34  switches the diagnosis information input screen SC 4  ( FIG. 22 ) to the diagnosis information input screen SC 3  ( FIG. 21 ). 
     By performing the above described processing, the drawing of the diagnosis target image “dt 1 ” and the diagnosis region “da 1 ” and the selection and the input of the diagnosis information are completed for the first input mode of the diagnosis target image (i.e., drawing of an area). 
     Input Mode of Diagnosis Target Image (Drawing of Line Pattern): 
     Hereinafter, a description is given of the detail of step S 24  ( FIG. 10 ) when the second input mode for inputting a line pattern of the diagnosis target image (i.e., drawing of a line pattern) is selected with reference to  FIGS. 12, and 23 to 28 . The second input mode for inputting the line pattern of the diagnosis target image (i.e., drawing of a line pattern) can be referred to as the second input mode of the diagnosis target image in this description. The second input mode of the diagnosis target image (i.e., drawing of a line pattern) is typically used when the diagnosis target is crack. 
       FIG. 12  is an example of a flowchart illustrating processing of the second input mode of the diagnosis target image (i.e., drawing of a line pattern).  FIG. 23  is an example of the diagnosis position input screen SC 2  when the second input mode of the diagnosis target image (i.e., drawing of a line pattern) is selected.  FIGS. 24 to 28  are examples of the diagnosis position input screen SC 2  when inputting the diagnosis target image (i.e., drawing of a line pattern) on the diagnosis position input screen SC 2 . 
     At first, in step S 23  ( FIG. 10 ), when the user selects the selection button “b 2 ” using the pointer “po,” the display control unit  34  sets the second input mode of the diagnosis target image (i.e., drawing of a line pattern) as illustrated in  FIG. 23 . 
     Then, as illustrated in  FIG. 24 , when the user identifies a start point “p 21 ” of a first diagnosis target element image “e 21 ” using the pointer “po,” the reception unit  32  receives the input of the start point “p 21 ” of the first diagnosis target element image “e 21 ” (step S 201 ). 
     Then, the display control unit  34  displays an enter button “co 21 ” and a cancel button “ca  21 ” around the start point “ 21 ” (step S 202 ). 
     As illustrated in  FIG. 25 , when the user identifies an end point “p 22 ” of the first diagnosis target element image “e 21 ” using the pointer “po,” the reception unit  32  receives the input of the end point “p 22 ” of the first diagnosis target element image “e 21 ” (step S 203 ). 
     Then, the display control unit  34  displays the diagnosis target element image “e 21 ” and a width input screen “ws 1 ” between the start point “p 21 ” and the end point “p 22 ,” and also displays an enter button “co 22 ” and a cancel button “ca 22 ” around the center of the first diagnosis target element image “e 21 ” (step S 204 ). As described above, the user can draw the diagnosis target element image by identifying the start point and the end point. 
     The width input screen “ws 1 ” is used for inputting a width of the line pattern when the diagnosis target element is crack. The width input screen “ws 1 ” is displayed near the first diagnosis target element image “e 21 ” between the start point “p 21 ” and the end point “p 22 .” The user inputs a value of width in the width input screen “ws 1 ” by referring to the numerical value in the development-view image  201  (e.g., numeral value written by a special chalk) and the detail information of inspection findings. When the user inputs the numerical value in the width input screen “ws 1 ,” the reception unit  32  receives the input numerical value, and the display control unit  34  displays the input numerical value (e.g., “0.5”) as illustrated in  FIG. 26 . 
     Then, the determination unit  35  determines whether the pressing of the enter button is received by the reception unit  32  (step S 205 ). If the determination unit  35  determines that the pressing of the enter button is not received by the reception unit  32  (step S 205 : NO), the sequence returns to step S 203 . 
     In  FIG. 26 , when the user identifies an end point “p 23 ” of a second diagnosis target element image “e 22 ” using the pointer “po,” the reception unit  32  receives the input of the end point “p 23 ” of the second diagnosis target element image “e 22 .” Since the start point of the second diagnosis target element image “e 22 ” matches the end point “p 22 ” of the first diagnosis target element image “e 21 ,” the user can omit the identification of the start point of the second diagnosis target element image “e 22 .” 
     Then, in step S 204 , the display control unit  34  displays the second diagnosis target element image “e 22 ” and a width input screen “ws 2 ” between the start point (i.e., end point “p 22 ”) and the end point “p 23 ,” and also displays an enter button “co 23 ” and a cancel button “ca 23 ” between the first diagnosis target element image “e 21 ” and the second diagnosis target element image “e 22 ” as illustrated in  FIG. 26 . When the user inputs a numerical value into the width input screen “ws 2 ,” the reception unit  32  receives the input numerical value, and the display control unit  34  displays the input numerical value (e.g., “0.7”) as illustrated in  FIG. 27 . In this description, the width input screen may be referred to as the second input screen. Further, if the diagnosis target element image is an image having a given area size, an area size input screen can be set. 
     As illustrated in  FIG. 27 , when the user presses the enter button “co 23 ” using the pointer “po,” the reception unit  32  receives the pressing, and the determination unit  35  determines that the pressing of the enter button is received by the reception unit  32  (step S 205 : YES). 
     Then, the determination unit  35  confirms the diagnosis target image (i.e., drawing of a line pattern), and the display control unit  34  displays a confirmed diagnosis target image “dt 2 ” (step S 206 ) as illustrated in  FIG. 28 . 
     Further, the display control unit  34  displays a rectangular-shaped diagnosis region “da 2 ” including the diagnosis target image “dt 2 ,” and the diagnosis information input screen SC 3  (step S 207 ). In this case, in order to make the diagnosis information input screen SC 3  conspicuous, the display control unit  34  can apply a masking on a portion other than the diagnosis information input screen SC 3 . 
     When the user selects and inputs the diagnosis information in the diagnosis information input screen SC 3 , and presses the “OK” button, the reception unit  32  receives the selection and input of the diagnosis information (step S 208 ). 
     By performing the above described processing, the drawing of the diagnosis target image “dt 2 ” and the diagnosis region “da 2 ” and the selection and the input of the diagnosis information are completed for the second input mode of the diagnosis target image (i.e., drawing of line pattern). 
     Input Mode of Diagnosis Region: 
     Hereinafter, a description is given of the detail of step S 24  ( FIG. 10 ) when the third input mode of the diagnosis region is selected with reference to  FIGS. 13, and 29  to  33 . The third input mode of the diagnosis region is used when the diagnosis target image is identified after identifying the diagnosis region in this description. 
       FIG. 13  is an example of a flowchart illustrating the steps of processing of the third input mode of the diagnosis region.  FIG. 29  is an example of the diagnosis position input screen SC 2  when the third input mode of the diagnosis region is selected.  FIGS. 30 to 33  are examples of the diagnosis position input screen SC 2  for inputting the diagnosis region. 
     At first, in step S 23  ( FIG. 10 ), when the user selects the selection button “b 3 ” using the pointer “po,” the display control unit  34  sets the third input mode of the diagnosis region as illustrated in  FIG. 29 . 
     Then, as illustrated in  FIG. 30 , when the user identifies a first vertex “p 31 ” of a tentative diagnosis region “da 03 ” using the pointer “po,” the reception unit  32  receives the input of the first vertex “p 31 ” of the tentative diagnosis region “da 03 ” (step S 301 ). 
     Then, the display control unit  34  displays an enter button “co 31 ” and a cancel button “ca  31 ” around the first vertex “p 31 ” (step S 302 ) as illustrated in  FIG. 30 . 
     Then, as illustrated in  FIG. 31 , when the user identifies a second vertex “p 32 ,” which is a diagonal vertex with respect to the first vertex “p 31 ” of the tentative diagnosis region “da 03 ,” using the pointer “po,” the reception unit  32  receives the input of the second vertex “p 32 ” as the diagonal vertex of the first vertex “p 31 ” of the tentative diagnosis region “da 03 ” (step S 303 ). 
     Then, as illustrated in  FIG. 31 , the display control unit  34  displays the tentative diagnosis region “da 03 ” as a rectangular shape having the first vertex “p 31 ” and the second vertex “p 32 ” as the diagonal vertexes, and also displays an enter button “co 32 ” and a cancel button “ca 32 ” around the center of the tentative diagnosis region “da 03 ” (step S 304 ). As above described, the user can draw the diagnosis region by identifying the two vertexes, each being the diagonal angles. 
     Then, the determination unit  35  determines whether the pressing of the enter button is received by the reception unit  32  (step S 305 ). If the determination unit  35  determines that the pressing of the enter button is not received by the reception unit  32  (step S 305 : NO), the sequence returns to step S 303 . In this case, after the user has identified the second vertex “p 32 ,” the first vertex “p 31 ” or the second vertex “p 32 ” is changed to enlarge or reduce the area of the tentative diagnosis region “da 03 .” 
     On the other hand, as illustrated in  FIG. 32 , when the user presses the enter button “co 32 ” using the pointer “po,” the reception unit  32  receives the pressing of the enter button “co 32 ,” and the determination unit  35  determines that the pressing of the enter button is received by the reception unit  32  (step S 305 : YES). 
     Then, the determination unit  35  confirms the tentative diagnosis region “da 03 ” (step S 306 ) as a diagnosis region “da 3 .” 
     As illustrated in  FIG. 33 , the display control unit  34  displays the diagnosis region “da 3 ” having a rectangular shape, which is the same as the confirmed tentative diagnosis region “da 03 ,” and the diagnosis information input screen SC 3  (step S 307 ). In this case, in order to make the diagnosis information input screen SC 3  conspicuous, the display control unit  34  can apply a masking on a portion other than the diagnosis information input screen SC 3 . 
     When the user selects and inputs the diagnosis information in the diagnosis information input screen SC 3 , and presses the “OK” button, the reception unit  32  receives the selection and the input of the diagnosis information (step S 308 ). 
     By performing the above described processing, the drawing of the diagnosis region “da 3 ” and the selection and input of the diagnosis information are completed for the third input mode of the diagnosis region. Thereafter, as similar to the first input mode of the diagnosis target image (i.e., drawing of an area) and the second input node of the diagnosis target image (i.e., drawing of a line pattern), the user can draw the diagnosis target image in the diagnosis region “da 3 .” 
     Change of Viewing Direction 
     Hereinafter, a description is given of process of shifting or changing of viewing directions of the development-view image  201  with reference to  FIGS. 34A to 34C and 35A to 35B .  FIG. 34A  illustrates a relationship between the tunnel  8  and the viewing directions,  FIG. 34B  illustrates a schematic diagram of the tunnel  8  viewed from the lower direction of the tunnel  8 , and  FIG. 34C  illustrates a schematic diagram of the tunnel  8  viewed from the upper direction of the tunnel  8 .  FIGS. 35A and 35B  are examples of diagnosis target images obtained by switching the viewing directions, in which  FIG. 35A  is an example of the diagnosis target image viewed from the lower direction of the tunnel  8 , and  FIG. 35B  is an example of the same diagnosis target image viewed from the upper direction of the tunnel  8 . 
     The development-view image  201  is an image acquired by looking up the wall and ceiling of the tunnel  8  from the inside of the tunnel  8  as illustrated in  FIG. 1 . This image is referred to as a “look-up image.” However, the observed inspection findings chart to be submitted to the government office might be required to be an image viewed from the outside of the tunnel  8  (i.e., above the tunnel  8 ) as illustrated in  FIG. 9C . This image is referred to as a “look-down image.” 
     As illustrated in  FIG. 34A , the tunnel  8  can be viewed from a look-up position of the tunnel  8  such as from an inside  81  of the tunnel  8  and from a look-down position of the tunnel  8  such as from an outside  82  of the tunnel  8 , in which the look-up position views the tunnel  8  into a upward direction from the inside  81  of the tunnel  8  and the look-down position views the tunnel  8  into a downward direction from the outside  82  of the tunnel  8 . Since the tunnel  8  may be built in undergrounds, such as hills and mountains, the look-down position may be a virtual position in some cases. 
     As illustrated in  FIG. 34A , when the inside  81  of the tunnel  8  is viewed along the viewing direction “sd 1 ,” the development-view image becomes the “look-up image” as illustrated in  FIG. 34B . In this case, the directions of virtual arrows “va 1 ” and “va 2 ” in  FIG. 34A , respectively, become the upward direction at the bottom left, and the downward direction at the upper right in  FIG. 34B . 
     Further, when the same image is viewed from the outside  82  of the tunnel  8  along the viewing direction “sd 2 ,” the development-view image becomes the “look-down image” as illustrated in  FIG. 34C . In this case, the directions of virtual arrows “va 1 ” and “va 2 ” in  FIG. 34A , respectively, become the downward direction at the upper left, and the upward direction at the bottom right in  FIG. 34C . That is, the look-up image and the look-down image are the inverted images. 
     When the display control unit  34  switches or inverts the top and bottom of the development-view image  201  while displaying the development-view image  201  on the display  308 , the display control unit  34  displays the diagnosis target element image by changing the y-coordinate the development-view image  201  from “Y” to “−Y” for the two-dimensional coordinates (X, Y) of the diagnosis target element image stored in the storage unit  3000 . 
     When the user presses a “switch to look-down” button “bc 1 ” on the diagnosis position input screen SC 2  in  FIG. 35A , the reception unit  32  receives the pressing of the “switch to look-down” button “bc 1 ,” and then the display control unit  34  switches or converts the image view from the look-up image ( FIG. 35A ) to the look-down image ( FIG. 35B ). Further, when the user presses a “switch to look-up” button “bc 2 ” on the diagnosis position input screen SC 2  in  FIG. 35B , the reception unit  32  receives the pressing of the “switch to look-up” button “bc 2 ”, and then the display control unit  34  switches or converts the image view from the look-down image ( FIG. 35B ) to the look-up image ( FIG. 35A ). With this configuration, the user can draw the diagnosis target element and the diagnosis region using any one of the look-up image and the look-down image. In this case, the coordinates of positions of the diagnosis target element image and diagnosis region stored in the storage unit  3000  are not changed, but the display control unit  34  changes the display style alone. 
     As to the above-described embodiment, by using the diagnosis processing terminal  3 , the user can draw the diagnosis target image indicating the diagnosis target on the image data (e.g., development view image) of the structural object (e.g., tunnel), and can input the diagnosis information including the diagnosis result of the diagnosis target. As described above, since the user can directly draw the diagnosis target image indicating the diagnosis target identified on the development-view image  201 , mistakes or errors that might occur during the document creation process can be reduced compared to the conventional methods of creating the final inspection report including the observed inspection findings chart or the like by comparing and checking a large number of documents and screens using hands and eyes of the user alone. 
     Further, by associating and storing the coordinates of positions of the diagnosis region and the diagnosis information of the diagnosis region using the diagnosis processing terminal  3 , the workload for creating the submission document including the diagnosis information of the structural object, such as the tunnel  8 , can be reduced compared to conventional methods. 
     Further, since the photograph images attached to the photograph ledger use the images corresponding to the diagnosis regions on the development-view image  201 , conventional manual work, such as a manual pasting of the observed-inspection findings photograph on the photograph ledger can be omitted, and thereby mistakes of pasting the observed-inspection findings photographs on the photograph ledger at a wrong position can be prevented. 
     Further, since the partial development-view image  202  can be switched between the look-up image  222   a  and the look-down image  222   b  as illustrated in  FIGS. 35A  and  35 B, the drawing of diagnosis target image and the inputting of diagnosis information of diagnosis target image can be performed using the development-view image  201  according to the user&#39;s preference of the look-up image  222   a  and the look-down image  222   b , thereby mistakes or errors that might occur during the document creation process can be reduced, in particular, prevented. Further, when submitting the final inspection report to the government office, the diagnosis processing terminal  3  can output the look-down image, required by the government office in some countries, so that the user error in the final inspection report, such as user&#39;s misunderstanding of the image direction, can be prevented. 
     Compared to conventional methods, which is performed mostly using manual works of one or more persons and mostly analog data and information requiring longer time and greater manual workloads and frequently causing mistakes and errors due to the complexity of information handling, by using the diagnosis processing terminal  3  and digitized data and information, as above described in the embodiment, the final inspection report including the diagnosis information of the inspected structural object can be created with less effort and fewer mistakes, and further, the final inspection report can be corrected easily even if the correction of the final inspection report is required after creating the final inspection report. The user can draw the diagnosis target image indicating the diagnosis target on the image of the structural object using the diagnosis processing terminal  3 , and can input the diagnosis information including the diagnosis result. Further, by storing the coordinates of the diagnosis region and the diagnosis information of the diagnosis region using the diagnosis processing terminal  3 , the final inspection report including the diagnosis information of the inspected structural object can be created with less effort and fewer mistakes compared to conventional methods. 
     As above described with reference to  FIG. 21 , the diagnostic information input screen SC 3  is displayed on the development-view image  201  of the tunnel  8 , but not limited to thereto. For example, as illustrated in  FIG. 36 , a diagnostic information input screen SC 5  can be displayed on the display  308  outside the development-view image  201  of the tunnel  8 . Further, the diagnostic information input screen SC 5  can be displayed on another display different from the display  308 , in which a plurality of displays is used. 
     In the above described embodiment, the structural object is exemplified as the tunnel, but not limited thereto. For example, the structural object includes piping or tubes used for transporting materials, such as gas, liquid, powder, and granular substance. Further, the structural object can be a vertical hole-shaped reinforced concrete structure, such as a hoistway used as an elevator shaft in which a lift or an elevator travels. 
     In the above-described embodiments, the size of the diagnosis region “da 1 ” is set greater than the size of the diagnosis target image “dt 1 ,” but not limited thereto. For example, the size of the diagnosis region “da 1 ” can be set same as the size of the diagnosis target image “dt 1 .” 
     Further, in the above-described embodiments, the reception unit  32  receives the drawing of the diagnosis target and the inputting of the diagnosis information of the diagnosis target from the user, but not limited thereto. For example, an artificial intelligence (AI) program executing on the diagnosis processing terminal  3  or the diagnosis management server  5  can search the diagnosis target region on the development-view image  201 , automatically select the diagnosis target, and measure the width of the diagnosis target. The selection of the diagnosis target also can be performed by a selection unit implemented by the artificial intelligence program. Further, the measurement of the width of the diagnosis target can be performed by a measurement unit implemented by the artificial intelligence program. 
     Further, in the above described embodiment, the display control unit  34  displays the diagnosis information input screen SC 3  on the development-view image  201 , but not limited thereto. For example, the diagnosis information input screen SC 3  can be displayed at a part of the periphery of the development-view image  201  if the development-view image  201  can be reduced in size and displayed with the diagnosis information input screen SC 3 . 
     Numerous additional modifications and variations are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the disclosure of this patent specification can be practiced otherwise than as specifically described herein.
