[Technical Field]

[0001] The present invention relates to a manhole cover management support system, a manhole cover management support method, and a program. [Background technology]

[0002] BACKGROUND ART Conventionally, there are known management methods and management systems for managing manhole covers using information about manhole covers installed at various locations.

[0003] In this regard, Patent Document 1 describes a system equipped with a server that stores information about each manhole (such as the manhole's identification number and its location). In the system described in Patent Document 1, a worker takes images of manholes installed in various locations using a terminal, adds information about the manhole cover to the image data of the captured image of the manhole, sends it to the server, and registers it as information about each manhole. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-077652 Summary of the Invention [Problem to be solved by the invention]

[0005] In conventional systems such as that described in Patent Document 1, image data can be associated with and managed for each manhole cover. However, conventional systems do not anticipate acquiring image data for a specific manhole cover from multiple users. Therefore, there is a risk that image data acquired for a specific manhole cover from multiple users cannot be appropriately managed.

[0006] Therefore, the present invention has been made in consideration of the above, and aims to appropriately manage image data from multiple users associated with a specific manhole cover. [Means for solving the problem]

[0007] A manhole cover management support system according to one embodiment of the present invention is a manhole cover management support system that supports the management of one or more manhole covers installed on the road, and includes an acquisition unit that acquires image data obtained by multiple users photographing one or more manhole covers, a first management unit that manages image data associated with one or more manhole covers photographed by each of the multiple users, and a generation unit that generates output information for outputting, in different formats, first information based on image data associated with a first user among the multiple users and second information based on image data associated with a second user different from the first user, for each of the one or more manhole covers.

[0008] A manhole cover management support method according to one embodiment of the present invention is a manhole cover management support method executed by a manhole cover management support system that supports the management of one or more manhole covers installed on the road, and includes the steps of acquiring image data obtained by multiple users taking images of one or more manhole covers, managing the image data associated with the one or more manhole covers taken by each of the multiple users in association with each of the multiple users, and generating output information for outputting, in different formats, first information based on image data associated with a first user of the multiple users and second information based on image data associated with a second user different from the first user, for each of the one or more manhole covers.

[0009] A program according to one embodiment of the present invention causes a computer that assists in the management of one or more manhole covers installed on the road to function as an acquisition unit that acquires image data obtained by multiple users photographing one or more manhole covers, a first management unit that manages image data associated with one or more manhole covers photographed by each of the multiple users by associating them with each of the multiple users, and a generation unit that generates output information for outputting, in different manners, first information based on image data associated with a first user among the multiple users and second information based on image data associated with a second user different from the first user, for each of the one or more manhole covers.

[0010] In this invention, the terms "unit," "device," and "system" do not simply mean physical means, but also include cases where the functions of the "unit," "device," or "system" are realized by software. Furthermore, the functions of one "unit," "device," or "system" may be realized by two or more physical means or devices, or the functions of two or more "units," "devices," or "systems" may be realized by one physical means or device. [Effects of the Invention]

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely examples, and are not intended to exclude various modifications or applications of techniques not explicitly described below. In other words, the present invention can be implemented in various modifications (such as combining the various embodiments) without departing from the spirit of the invention. Furthermore, in the following description of the drawings, identical or similar parts are denoted by the same or similar reference numerals.

[0014] <Configuration overview> FIG. 1 is a diagram illustrating an overview of a manhole cover management support system 1 according to an embodiment of the present invention. FIG. 1 is a diagram illustrating an overview of a manhole cover management support system according to an embodiment of the present invention. (1) A user takes an image of a manhole cover on a road using, for example, their own mobile phone or the like (e.g., user terminal 20). The user operates the user terminal 20 to send image data of the captured manhole cover to a server (manhole cover management support device 10). (2) The manhole cover management support device 10 acquires the image data and manages the acquired image data for each manhole cover. The manhole cover management support device 10 manages image data captured by multiple users for one manhole cover, for each user. FIG. 1 shows an example of handling image data captured by user A and user B. (3) The manhole cover management support device 10 displays an icon at the location where the manhole cover is installed on a map, and generates information (hereinafter sometimes referred to as "output information") that enables image data (the user's own image data, image data of others) for each manhole cover to be output. The generated output information can be accessed by each user terminal 20. (4) For example, user A operates his / her user terminal 20 to cause the user terminal to output an output screen G0a showing the location of manhole covers on a map based on the output information. By performing an operation input (e.g., a tap operation or a selection operation) on each icon shown on G0a, the user can check image data captured by multiple users and associated with each manhole cover corresponding to the icon on the output screen G0b. In this way, the manhole cover management support system 1 may be used, for example, at a manhole cover photography event held by a local government with the aim of ensuring the safety of infrastructure. Note that the above embodiment is merely one embodiment of the present invention, and the present invention is not limited to the above embodiment.

[0015] FIG. 2 is a diagram showing the network configuration of the manhole cover management support system 1 according to an embodiment of the present invention.

[0016] As shown in Figure 2, the manhole cover management support system 1, for example, includes a manhole cover management support device 10 that supports the management of manhole covers, and a user terminal 20 operated by a user that captures image data of the manhole covers, which are connected to each other so that they can communicate with each other via a communication network N.

[0017] The communication network N may be, for example, the Internet, a LAN, a telephone line, an in-house network, a mobile communication network, Bluetooth (registered trademark), WiFi (Wireless Fidelity), any other communication line, or a combination thereof, regardless of whether it is wired or wireless. Furthermore, a plurality of manhole cover management support devices 10 and a plurality of user terminals 20 may be included.

[0018] For the sake of explanation, as shown in FIG. 2, the user terminal used by user A may be designated by the symbol "20a" and the user terminal used by user B by the symbol "20b".

[0019] The manhole cover management support device 10 and the user terminal 20 may be equipped with a communication interface for wired or wireless communication, and may also be, for example, a general-purpose personal computer, a smartphone, a tablet terminal, or the like.

[0020] In the manhole cover management support system 1, the manhole cover management support device 10 is a device that acquires image data obtained by multiple users taking images of multiple manhole covers that are subject to management and are installed on the road in a specified area, and manages information for each manhole cover corresponding to each user who took the image data.

[0021] The predetermined area may be any fixed geographical area, for example, an area corresponding to an area managed by a local government, or may be any fixed geographical area that is arbitrarily determined.

[0022] The user who takes an image of a manhole cover placed on the road may be anyone who can operate a terminal (user terminal 20) that takes an image of the manhole cover. For example, the user may be a person in charge of managing the manhole covers that are subject to management in the local government mentioned above, or a passerby who can take an image of the manhole cover at will.

[0023] The user moves to a location where a predetermined manhole cover is installed and takes an image of the manhole cover installed on the road by operating the user terminal 20. The user operates the user terminal 20 to send image data of the manhole cover to the manhole cover management support device 10.

[0024] The installation location of each manhole cover may be known by the user, for example, by having the manhole cover management support device 10 link the location information of each manhole cover contained in the ledger information 301 of the manhole covers to be managed, as shown in Figure 3, to the user terminal 20.

[0025] The ledger information is, for example, information in a management book kept by a local government that maintains and manages manholes to manage each manhole cover. The ledger information may, for each manhole, associate and manage the manhole cover's identification information, installation location, installation date, manhole cover model, information on the manhole cover's condition, image data, and information on the results of regular inspections.

[0026] In addition, the manhole cover management support device 10 generates information (hereinafter sometimes referred to as "output information") for outputting, for example, an image (e.g., an icon) showing the manhole cover linked to the image data on a map showing the specified area, based on information corresponding to each user who captured image data for each manhole cover (hereinafter referred to as "manhole cover information").

[0027] The user, for example, operates user terminal 20 to acquire output information, and based on the output information, checks an output image in which icons indicating manhole covers linked to each image data are superimposed on a map showing the specified area. Note that if multiple users have acquired image data for each manhole cover, the image data may be output in a manner that allows each of the users to be identified.

[0028] <Functional section configuration> Fig. 3 is a diagram showing an example of the functional configuration of a manhole cover management support device 10 according to one embodiment of the present invention. As shown in Fig. 3, the manhole cover management support device 10 functionally comprises a communication unit 11 that transmits and receives various information to and from the user terminal 20 shown in Fig. 2, a control unit 12 that controls various processes in this embodiment, and a recording unit 13 that records information for executing the various processes and the execution results of the various processes.

[0029] The manhole cover management support device 10 is configured, for example, by a server device configured as a computer system, or a cloud server, etc., and is implemented by a software program. The program may be provided by being downloaded from outside the manhole cover management support device 10 via a predetermined network, or may be provided by various computer-readable information recording media such as CD-ROMs and DVD-ROMs.

[0030] The control unit 12 functionally comprises an acquisition unit 121, a first management unit 122, a generation unit 123, and a second management unit 124. Each functional unit will be described below.

[0031] The acquisition unit 121 acquires, from a plurality of user terminals 20, image data obtained by a plurality of users capturing images of one or a plurality of manhole covers provided on the road.

[0032] As shown in FIG. 4, the image data may be, for example, an image of the road on which each manhole cover is installed taken by a user terminal 20 from a predetermined distance (G1), and / or an image of the manhole cover taken from above (G2).

[0033] Furthermore, each image data may be associated with each captured manhole cover. In this case, for example, the manhole cover management support device 10 or the user terminal 20 may execute a process of associating information on the manhole cover corresponding to the captured image data, based on the ledger information 301 shown in FIG.

[0034] The first management unit 122 is a functional unit that manages image data associated with each manhole cover captured by a plurality of users as "manhole cover information" by associating the image data with each of the plurality of users.

[0035] Fig. 5 is a diagram showing an example of manhole cover information. D111 is manhole cover information for managing image data of manhole covers photographed by user A. D112 is manhole cover information for managing image data of manhole covers photographed by user B. In this way, the manhole cover information associates each manhole cover with each piece of image data of the manhole cover for each of multiple users.

[0036] As shown in FIG. 5, the manhole cover information includes, for example, items for manhole cover Da and image data Db. Manhole cover Da is an item in which information indicating the image of the manhole cover that has been photographed is stored. This information only needs to be able to identify each manhole cover, and may indicate the name of each manhole cover or an identification code for identifying each manhole cover on the system. Image data Db is an item in which information related to the image data described above is stored. For example, a file name indicating the image data may be stored.

[0037] Although not shown, the manhole cover information may include location information for each manhole cover corresponding to image data associated with each manhole cover. The location information is linked to the image data of each manhole cover, for example, based on ledger information 301 shown in FIG. 3. The location information may also be, for example, information obtained by a GPS (Global Positioning System), information indicating the location in units of a postal code, and / or information indicating the location in units of an address. Location information of the user terminal 20 itself when the user terminal 20 captured the image of the manhole cover may also be linked to the image data of each manhole cover.

[0038] The generation unit 123 generates output information for outputting, in different modes, first information based on image data associated with a first user (e.g., user A) among multiple users and second information based on image data associated with a second user (e.g., user B) different from the first user, for one or more manhole covers.

[0039] The first information based on the image data of user A may correspond to, for example, D111 in FIG. 5, and the second information based on the image data of user B may correspond to, for example, D112 in FIG.

[0040] Here, the output information is information for outputting, for each manhole cover corresponding to the image data, the first information and the second information in different modes so that they are distinguishable on a predetermined screen output to, for example, user terminal 20. As a result, if image data for one manhole cover is obtained from multiple user terminals 20, for example, image data captured by multiple users for one manhole cover can be output on the screen in a manner that allows each user to distinguish the image data.

[0041] The output information may also include output information for outputting, in different formats, a first image corresponding to the first information and a second image corresponding to the second information, which are associated with one or more manhole covers on the map.

[0042] Fig. 6 is a diagram showing an example of an output screen G3 output to the user terminal 20a based on the generated output information. The first image corresponds to G3a in Fig. 6. The second image corresponds to G3b in Fig. 6. In this way, the first image and the second image may be icons indicating the positions of manhole covers on a map.

[0043] As shown in G3 of FIG. 6, the first image G3a and the second image G3b may be icons output in different modes. For example, G3a and G3b may be icons of different colors. Furthermore, for example, the first image G3a may be colored to indicate that it corresponds to user A, and the second image G3b may be colored to indicate that it corresponds to another user (e.g., user B). Additionally, G3a and G3b may be icons of different shapes or sizes. This allows, for example, user A to check on the map output on the screen of user terminal 20a how many manhole covers correspond to the image data captured by him / her, and to distinguish them from manhole covers corresponding to image data captured by other users.

[0044] The output information may also include output information for outputting the first information and the second information in different manners using a list format, when an operation input is made for a specific third image among one or more third images corresponding to each manhole cover placed on the map, in association with the specific manhole cover corresponding to the specific third image.

[0045] Fig. 7 is a diagram for explaining an example of a third image being output on a map. G4 in Fig. 7 is an example of an output screen in which third images corresponding to each manhole cover placed on the map are output to the user terminal 20a based on the output information.

[0046] The third image may correspond to one or more manhole covers placed on the road, and may be an icon indicating the location on the map where the manhole covers are installed.

[0047] The third image may be linked to, for example, the ledger information 301. This makes it possible to show the positions of installed manhole covers on a map with icons, regardless of whether image data is available.

[0048] For example, user A performs an operation input (for example, a tap operation or a click operation) on a specific third image among the third images (icons) output to user terminal 20a. Then, for the manhole cover corresponding to the specific third image for which the operation input was performed, the first information and the second information are output in different modes. Note that if the first information and / or the second information does not exist, it does not need to be output.

[0049] As shown in G4b in Fig. 7, for the manhole cover corresponding to the specific third image G4a for which operation input has been performed, the first information and the second information are output in different forms using a list format. This makes it possible to output information based on the multiple image data for one manhole cover in a manner that allows the multiple users to be identified.

[0050] The second management unit 124 is a functional unit that manages, for example, point information given by capturing an image of a manhole cover, in association with each of a plurality of users.

[0051] FIG. 8 shows an example of point information. The point information is, for example, information indicating points awarded to each of multiple users for capturing an image of a manhole cover. As shown by 302 in FIG. 8, the point information includes, for example, items for user name Dc and points Dd. The user name Dc is an item in which information indicating each user is stored. The user name may be the name of the corresponding user, or may be an identification code identifiable on the system. The points Dd is an item including points awarded to each user who captured an image of a manhole cover. The points may be the total number of points held by the corresponding user, or each point obtained each time an image of a manhole cover is captured may be stored individually.

[0052] The output information may also include output information for outputting rankings of a plurality of users based on point information.

[0053] As shown in G5 of FIG. 9, for example, the manhole cover management support device 10, based on the output information, associates user names with points corresponding to the user names and outputs a ranking screen to the user terminal 20 in descending order of points held by the user. Furthermore, when a user performs an operation input on the ranking screen based on the output information, the manhole cover management support device 10 may output image data captured by the user displayed on the ranking screen for each user. For example, when an operation input (e.g., a tap operation or a click operation) is performed on the field indicated by G5a in FIG. 9 on the user terminal 20, a list (G51) of image data captured by the "name" user in the ranking is output. Furthermore, when an operation input (e.g., a tap operation or a click operation) is performed on the field indicated by G5b in FIG. 9 on the user terminal 20, a list (G52) of image data captured by the "user-text" user in the ranking is output. This allows the user to check each image data captured by themselves and / or others from the ranking screen.

[0054] Here, we will explain the points that a user can earn by capturing image data. For example, when a user acquires image data of a manhole cover captured by the user terminal 20a, the points are a numerical value (points) of the number of points that the user can earn based on the image data. For example, the manhole cover management support device 10 may predetermine points for each manhole cover and award those points when it acquires image data of a manhole cover for which points have been assigned, or it may calculate the points to be awarded using a predetermined calculation method based on the acquired image data.

[0055] Points may also be awarded based on the acquisition time of image data obtained by capturing an image of a manhole cover. For example, when the acquisition unit 121 acquires image data of a certain manhole cover (hereinafter referred to as "manhole cover A") from a user terminal 20, the highest points may be awarded to the user terminal 20 that transmitted the image data of manhole cover A with the earliest acquisition time. Points may be awarded in stages, such as 5 points for the user corresponding to the user terminal that acquired the image data earliest, 3 points for the next user, and 1 point for each subsequent user. Points may also be calculated so that, for example, 5 points are awarded for capturing image data within a predetermined time period, and 3 points are awarded for capturing image data later. This allows relatively high points to be awarded to users who provide image data that is acquired early, thereby encouraging users to capture images of manhole covers and transmit image data.

[0056] Points may also be awarded based on the locations of one or more manhole covers. For example, when the acquisition unit 121 acquires image data of manhole cover A from a user terminal, the points may be calculated so that the farther the location of manhole cover A is from a predetermined location, the higher the points. For example, points may be based on the distance from the location of a local government office. Alternatively, points may be based on the distance from a predetermined location, for example, to each station (railroad stop) in a city. The location of a manhole cover may be determined based on, for example, location information included in the ledger information 301. This makes it possible to adjust the points awarded when image data is acquired depending on the location of the installed manhole cover, and can encourage users to acquire image data of manhole covers that are relatively difficult for users to photograph, such as those in suburban areas far from urban areas.

[0057] Points may also be awarded based on information output by the learning model. Note that the multiple learning models described below may be generated by the manhole cover management support device 10, or may be generated by an external device different from the manhole cover management support device 10.

[0058] The learning model may be, for example, a learning model generated based on image data of one or more manhole covers acquired in the past and data identifying the types of one or more manhole covers corresponding to the image data. The learning model may be, for example, a model trained based on ledger information 301 recorded in recording unit 13 of Fig. 3 using, as training data, image data of each manhole cover acquired in the past and information indicating the type of manhole cover corresponding to the image data. In this case, when image data acquired from user terminal 20 is input, the learning model outputs information indicating the type of manhole cover corresponding to the image data (hereinafter referred to as "type determination data").

[0059] Manhole cover types are classified into, for example, "concrete," "hexagonal pattern," "YO pattern," and "Bay Bridge pattern," etc. Manhole cover types may also include those classified into "local manhole covers" that reflect the characteristics of the local government where they are installed, and "designer manhole covers" that reflect designs that take into consideration the streetscape.

[0060] Points are calculated based on type determination data corresponding to the image data. For example, if type determination data for a relatively old manhole cover is output based on the image data, the manhole cover management support device 10 may calculate high points from the perspective of manhole cover management, as there are concerns about deterioration. Furthermore, if type determination data indicating that the manhole cover has an unusual design (for example, a designer manhole cover) is output, relatively high points may be awarded.

[0061] Furthermore, the learning model may be, for example, a learning model generated based on image data of one or more manhole covers acquired in the past and data determining the state of one or more manhole covers corresponding to the image data. The learning model may be, for example, a model trained based on ledger information 301 recorded in recording unit 13 of Fig. 3 using image data of each manhole cover acquired in the past and information indicating the state of the manhole cover corresponding to the image data as training data. In this case, when image data acquired from user terminal 20 is input, the learning model outputs information indicating the state of the manhole cover corresponding to the image data (hereinafter referred to as "state determination data").

[0062] The condition of the manhole cover includes, for example, a case where the condition of the manhole cover is "abnormal" and a case where the condition is "normal." Abnormalities refer to, for example, "damage," "misalignment," "looseness," and / or "corrosion," etc.

[0063] Points are calculated based on the condition determination data corresponding to the image data. For example, if condition determination data indicating a "misaligned" condition is output based on the image data, the manhole cover management support device 10 may calculate a higher point than image data for which condition determination data indicating "no abnormality" is output. Furthermore, higher points may be awarded to image data for which multiple abnormalities are determined.

[0064] The learning model may also be a model generated based on data regarding the installation date and location of each manhole cover and data regarding the degree of deterioration of one or more manhole covers. The learning model may be a model trained using, as training data, data regarding the installation date and location of each manhole cover and information indicating the degree of deterioration of the manhole cover corresponding to the data, based on ledger information 301 recorded in recording unit 13 of FIG. 3. The information indicating the degree of deterioration may be based, for example, on information regarding the inspection and inspection results of the manhole cover recorded in ledger information 301. For example, upon acquiring image data from user terminal 20, the learning model references the location information of the manhole cover associated with the image data and outputs data indicating a prediction of the future deterioration risk for the manhole cover corresponding to the location information (hereinafter, "deterioration prediction data").

[0065] D121 in Figure 10 is an example of deterioration prediction data output by the learning model. While manhole covers are expected to deteriorate over time if they were installed a long time ago, there are other factors that contribute to deterioration. For example, the installation location can affect the extent of deterioration, depending on the traffic volume and road conditions, making deterioration prediction complex. Therefore, by training the learning model to learn information about the installation date and location of a manhole cover, as well as information about the inspection and survey results of the manhole cover, the learning model can output deterioration prediction data for the manhole cover using image data of the manhole cover and location information associated with the image data as input. D121 in Figure 10 indicates that there is a risk of "rattle," one type of manhole cover deterioration, occurring in 2027 ("medium risk").

[0066] The points are calculated based on the deterioration prediction data corresponding to the image data. For example, if the learning model outputs, based on the image data, that the manhole cover corresponding to the image data is at risk of deterioration in the future, the manhole cover management support device 10 may award the points relatively higher than when an image of a manhole cover with a low risk of deterioration is captured.

[0067] The recording unit 13 records various types of information. As shown in Fig. 3, the recording unit 13 may record, for example, ledger information 301 including information about manhole covers to be managed. The recording unit 13 may also record point information 302 that manages points held by each user.

[0068] The following describes the processing executed in the manhole cover management support system 1. Here, we will explain a mode in which image data of multiple users is output for each of multiple manhole covers on a map, based on image data of multiple manhole covers placed on roads in a predetermined area taken by multiple users.

[0069] <Output processing of the first and second images> FIG. 11 is a flowchart showing an example of a process for outputting a first image and a second image according to an embodiment of the present invention.

[0070] As a premise for this processing, manhole cover management support application software including this processing is downloaded from, for example, a predetermined site on a network or a recording medium, and stored so as to be executable in the manhole cover management support device 10 shown in Figure 2. Then, when an instruction to execute the manhole cover management support application software is given, program operation based on this software begins. Note that the software is also executed in advance on the user terminal 20 so that it operates appropriately as an element of the manhole cover management support system 1.

[0071] The manhole cover management support device 10 acquires, from the user terminal 20a, image data of a manhole cover (for example, manhole cover A) captured in a predetermined area by the user A operating the user terminal 20a (step S11).

[0072] The manhole cover management support device 10 manages a plurality of image data of manhole cover A taken by a plurality of users, including user A, in association with each user as "manhole cover information" (step S12).

[0073] For example, for manhole cover A, the manhole cover management support device 10 generates output information for outputting a first image (icon) and a second image (icon) corresponding to first information based on image data corresponding to user A among multiple users and second information based on image data corresponding to another user other than user A so that the first image (icon) and the second image (icon) can be distinguished on a map (step S13).

[0074] Based on the generated output information, the manhole cover management support device 10 causes the user terminal 20a to output, for example, an icon that outputs first information based on image data corresponding to user A and an icon that outputs second information based on image data corresponding to another user, at a location on a map indicating the installation location of manhole cover A (step S14). Here, if image data of multiple users has been acquired for one manhole cover, the icons may be superimposed, or the icons may be output on the screen shifted by a certain amount. In this way, it is possible to confirm that image data of multiple users is associated with one manhole cover. Furthermore, by inputting an operation on the output icon, multiple pieces of information, including the first information and the second information, may be output in different formats using a list format for the manhole cover corresponding to the icon for which the operation input was made.

[0075] <Modification> Below, we will explain modified examples of the manhole cover management support device 10 according to one aspect of the present invention. Only configurations that differ from the configuration of the manhole cover management support device 10 described above will be explained, and unless otherwise specified, the content will be assumed to be the same as that described above.

[0076] In the manhole cover management support device 10 according to the modified example, the first information may include information on the state of the manhole cover imaged by user A for each manhole cover.

[0077] The information regarding the condition of the manhole cover includes, for example, cases in which the condition of the manhole cover is "abnormal" and cases in which it is "normal." An abnormality may be information indicating, for example, "damage," "misalignment," "looseness," and / or "corrosion."

[0078] For example, as shown in G61 in FIG. 12, the manhole cover assistance management device 10 may output to the user terminal 20 an image capture screen of image data of a manhole cover. After the image data is captured, the manhole cover assistance management device 10 may output to the user terminal 20 an input screen for information regarding the condition of the manhole cover, as shown in G62, to acquire information regarding the condition of the manhole cover along with the image data. The user may input information regarding the condition of the manhole cover in the section indicated by G62a on the input screen G62 output to the user terminal 20. In the case of FIG. 12, after capturing the image data of the manhole cover on screen G61, the user operates the checkboxes in the input field G62a of the input screen G62 if there is "damage" or "looseness," and freely enters any other information regarding the condition in the "comments" field. This allows information indicating the condition of the manhole cover to be included in the manhole cover corresponding to the first information.

[0079] Similarly, the second information may also include information regarding the state of the manhole cover.

[0080] In this case, the output information may be information for outputting icons corresponding to abnormal manhole covers on the map based on the "information related to the condition of the manhole cover" included in the first information and the second information. This makes it possible to cause the user terminal 20 to output, for example, only icons corresponding to abnormal manhole covers on the map.

[0081] Furthermore, the output information may be information for preferentially outputting information about abnormal manhole covers among the manhole covers in the list G4b of FIG. 7 when an operation input (e.g., a tap operation or a click operation) is made to the icon G4a shown in FIG. 7 based on the "information about the condition of the manhole cover" included in the first information and the second information.

[0082] <Hardware configuration> 18, an example of a hardware configuration in which the above-described manhole cover management support device 10 and user terminal 20 are realized by a computer 1000 will be described. Note that the functions of each device can also be realized by dividing them into multiple devices.

[0083] As shown in FIG. 13, a computer 1000 includes a processor 1001, a memory 1002, a storage device 1003, an input I / F unit 1004, a data I / F unit 1005, a communication I / F unit 1006, and a display device 1007.

[0084] The processor 1001 controls various processes in the computer 1000 by executing a program (for example, a server program or a user program) stored in the memory 1002. For example, the various functional units provided in the control unit 12 of the manhole cover management support device 10 and the control unit of the user terminal 20 can be realized by the processor 1001 executing a program temporarily stored in the memory 1002.

[0085] The memory 1002 is a storage medium such as a RAM (Random Access Memory), etc. The memory 1002 temporarily stores the program code of the program executed by the processor 1001 and data required when the program is executed.

[0086] The storage device 1003 is a non-volatile storage medium such as a hard disk drive (HDD) or flash memory. The storage device 1003 stores an operating system and various programs for implementing the above-mentioned configurations. In addition, the storage device 1003 can also store the above-mentioned information / data. Such programs and data are loaded into the memory 1002 as needed and are referenced by the processor 1001.

[0087] The input I / F unit 1004 is a device for receiving input from a user. Specific examples of the input I / F unit 1004 include a keyboard, a mouse, a touch panel, various sensors, and a wearable device. The input I / F unit 1004 may be connected to the computer 1000 via an interface such as a USB (Universal Serial Bus).

[0088] The data I / F unit 1005 is a device for inputting data from outside the computer 1000. A specific example of the data I / F unit 1005 is a drive device for reading data stored in various storage media. The data I / F unit 1005 may be provided outside the computer 1000. In this case, the data I / F unit 1005 is connected to the computer 1000 via an interface such as a USB.

[0089] The communication I / F unit 1006 is a device for performing data communication via the Internet N, either wired or wirelessly, with devices external to the computer 1000. The communication I / F unit 1004 may be provided external to the computer 1000. In this case, the communication I / F unit 1006 is connected to the computer 1000 via an interface such as a USB.

[0090] The display device 1007 is a device for displaying various types of information. Specific examples of the display device 1003 include a liquid crystal display, an organic EL (Electro-Luminescence) display, and a display of a wearable device. The display device 1007 may be provided outside the computer 1000. In this case, the display device 1007 is connected to the computer 1000 via, for example, a display cable. Furthermore, when a touch panel is adopted as the input I / F unit 1004, the display device 1007 can be configured as an integrated unit with the input I / F unit 1004.

[0091] The components of the server described in the above embodiment are assumed to be implemented in cooperation with other hardware by the processor 1001 executing a program stored in the storage device 1003. In other words, these components can be considered as software or firmware, or as corresponding hardware, and in both of these concepts, they can also be described as "functions," "means," "parts," "processing circuits," "units," or "modules," and can be interpreted as such.

[0092] <Summary> The manhole cover management support system 1 is a manhole cover management support system that supports the management of one or more manhole covers installed on the road, and includes an acquisition unit 121 that acquires image data obtained by multiple users capturing images of one or more manhole covers, a first management unit 122 that manages image data associated with one or more manhole covers captured by each of the multiple users, and a generation unit 123 that generates output information for outputting, in different formats, first information based on image data associated with a first user (user A) among the multiple users and second information based on image data associated with a second user (user B) different from the first user, for each of the one or more manhole covers.

[0093] This allows for appropriate management of image data from multiple users associated with a specific manhole cover, even when image data for one specific manhole cover is acquired from multiple user terminals 20. Furthermore, output information can be generated for each manhole cover, which is output to the screen in a manner that allows the corresponding multiple users to be identified.

[0094] The output information also includes output information for outputting, in different formats, a first image corresponding to the first information and a second image corresponding to the second information, which are associated with one or more manhole covers on the map.

[0095] As a result, for example, when image data for one manhole cover is acquired from multiple user terminals 20, it is possible to output an image (for example, an icon) for each manhole cover that allows the corresponding multiple users to be identified on the map.

[0096] The output information also includes output information for outputting the first information and the second information in different manners using a list format, when an operation input is made for a specific third image among one or more third images corresponding to one or more manhole covers placed on the map, in association with the specific manhole cover corresponding to the specific third image.

[0097] This allows, for example, when image data for one manhole cover is acquired from multiple user terminals 20, information based on the image data acquired from the corresponding multiple users can be output in list form for each manhole cover.

[0098] In addition, the manhole cover management support device 10 further includes a second management unit 124 that manages point information awarded to multiple users by capturing images of one or more manhole covers, in association with each of the multiple users, and the output information includes output information for outputting a ranking of the multiple users based on the point information.

[0099] This allows users to earn points based on the manhole covers they photograph, and by being able to check their ranking based on the points they have, it encourages users to photograph manhole covers.

[0100] The output information also includes output information for outputting image data associated with the first user on the ranking output screen based on operation input associated with the first user, and outputting image data associated with the second user on the ranking output screen based on operation input associated with the second user.

[0101] This allows the user terminal 20 to output image data captured by the user A or a user other than the user A, for example.

[0102] The point information also includes point information that is awarded based on the acquisition time of image data obtained by multiple users capturing images of one or multiple manhole covers.

[0103] This allows users to earn points according to the manhole covers they photograph, thereby encouraging users to photograph manhole covers.

[0104] The point information also includes point information that is awarded based on the location of one or more manhole covers.

[0105] This can encourage users to obtain image data for manhole covers that are difficult to obtain image data for, for example, manhole covers in the suburbs.

[0106] The point information also includes point information that is awarded based on information regarding the type of manhole cover that is output by inputting image data captured by multiple users into a learning model that is generated based on image data of one or more manhole covers that have been acquired in the past and data that identifies the type of one or more manhole covers that correspond to the image data.

[0107] This allows the points to be awarded to be calculated based on the type determination data output by the learning model, providing a system for awarding points according to the type of manhole cover corresponding to the image data.

[0108] The point information also includes point information that is awarded based on information regarding the state of the manhole cover that is output by inputting image data captured by multiple users into a learning model that is generated based on image data of one or more manhole covers that have been acquired in the past and data that determines the state of one or more manhole covers that correspond to the image data.

[0109] This allows the points to be awarded to be calculated based on the condition assessment data output by the learning model, providing a system for awarding points according to the condition of the manhole cover corresponding to the image data (e.g., whether or not there is an abnormality, etc.).

[0110] The first management unit 122 also manages image data associated with the one or more manhole covers photographed by each of the multiple users in association with the positional information of each of the one or more manhole covers, and the point information includes point information that is awarded based on information for predicting the deterioration of a specific manhole cover that is output by inputting the positional information of a specific manhole cover from among the one or more manhole covers into a learning model that has been trained based on data regarding the installation time and installation position of the one or more manhole covers and data regarding the degree of deterioration of the one or more manhole covers.

[0111] This allows the points to be awarded to be calculated based on the deterioration prediction data output by the learning model, which, for example, can encourage the acquisition of image data and increase the predictability of future deterioration of manhole covers.

[0112] In addition, the first information includes information regarding the condition of the manhole cover photographed by the first user for each of one or more manhole covers, the second information includes information regarding the condition of the manhole cover photographed by the second user for each of one or more manhole covers, and the output information includes output information for outputting a third image corresponding to an abnormal manhole cover among the one or more manhole covers on a map based on the first information and the second information.

[0113] This makes it possible to display on the screen on the map an icon indicating only the manhole cover that is abnormal.

[0114] Furthermore, the first information includes information regarding the condition of one or more manhole covers photographed by a first user, the second information includes information regarding the condition of one or more manhole covers photographed by a second user, and the output information includes output information for preferentially outputting information regarding an abnormal manhole cover among one or more manhole covers on a list when an operation input is made for the specific third image based on the first information and the second information.

[0115] This means that when an operation is made on an icon on the map indicating that a manhole cover has been installed, information regarding the abnormality can be output to a higher level, thereby improving the accuracy of manhole cover management.

[0116] <Other embodiments> The above-described embodiments are provided to facilitate understanding of the present invention and are not to be construed as limiting the present invention. The present invention may be modified or improved (for example, by combining the embodiments or omitting some of the components of the embodiments) without departing from the spirit thereof, and the present invention also includes equivalents thereof.
