(Operation of the first embodiment)
[1] Outline of Operation FIG. 10 is a flow chart showing the flow of the overall operation of the repair planning system according to the first embodiment of the present invention.
As shown in the figure, first, the measurement vehicle 10 irradiates a laser beam to the landform and a tangible object while traveling on a road, and acquires point cloud data of the tangible object (tangible object point cloud data). or a tangible object to obtain image data of the tangible object (tangible object image data) (step S1).

Next, the repair plan formulation device 20 acquires point cloud data and image data from the measurement vehicle 10, and generates data related to the point cloud data (such as superimposed image data described later) based on the acquired data. (Step S2).

Next, the repair plan formulation device 20 performs image recognition for each tangible object from the obtained point cloud data, extracts tangible object point cloud data and tangible object image data for each individual tangible object, and extracts these extracted data are associated with each other to generate basic data (tangible object basic data) of each tangible object (step S3).

Next, the repair plan formulating device 20 detects damage to each tangible object based on the tangible object point cloud data and the tangible object image data, and determines the damage rank of each tangible object (step S4).

For example, in step S5, the repair plan formulation device 20 additionally registers each item such as the manufacturing date and the last repair date of the tangible item in the tangible item basic data.

Next, the repair plan formulating device 20 determines a repair priority rank for each tangible object based on the damage rank, and formulates a repair plan for the tangible object based on the determined repair priority rank (step S6).

In this way, the repair plan formulation device 20 detects damage to each tangible object and formulates a repair plan for the tangible object indicating which tangible object should be repaired preferentially according to the degree of damage. Therefore, it is possible to appropriately repair tangible objects within a limited budget.
Each operation of steps S1 to S6 will be described in detail below.

[2] Acquisition of point cloud data (step S1)
(1) Acquisition of Point Cloud Data Hereinafter, an operation for acquiring point cloud data while the measurement vehicle 10 is traveling on a road or stopped will be described.

The measurement vehicle 10 irradiates the surroundings of the road with a laser using a laser scanner 13 provided in the own vehicle while the vehicle is running or stopped. At this time, the optical axis of the laser is scanned in the vertical and horizontal directions by changing the elevation/depression angle and the azimuth angle, and a laser pulse is emitted at every minute angle within the scanning range. Then, the laser scanner 13 receives the reflected light of the emitted laser.
Further, the control unit 11 acquires the laser emission time and the reflected light reception time of the object from the timer unit 16, and controls the laser scanner 13 and the object based on the time from the laser emission to the reflected light reception. Measure the distance between objects.
Furthermore, the laser scanner 13 measures the light intensity of the received reflected light.

Further, while the measurement vehicle 10 is running or stopped, information on the laser emission direction from the laser scanner 13, information on the current position of the measurement vehicle 10 from the GPS 14 or the odometer 18, and information indicating the attitude of the measurement vehicle 10 from the IMU 15. are obtained respectively.
Each of these pieces of information is associated with the time information kept by the clock unit 16 and stored in the information storage unit 12 .

Since the position/posture of the laser scanner 13 has a fixed relationship with the position/posture of the measurement vehicle 10, the control unit 11 controls the laser scanner 13 based on the information on the position/posture of the measurement vehicle 10 and the laser emission direction. Find the position and posture of
Based on information such as the distance between the laser scanner 13 and the object and the information indicating the position and orientation of the laser scanner 13, the control unit 11 determines the space of each coordinate point forming the object that reflected the laser pulse. Calculate point cloud data representing coordinates (three-dimensional coordinates).
For example, the coordinates are numerical values that can be converted into actual distances, such that "1" in the coordinates of each coordinate point indicates "10 km".
The spatial coordinate information of the point cloud data of each coordinate point forming the point cloud is associated with the latitude/longitude information obtained by the GPS 14 .
Also, the spatial coordinate information of the point cloud data may be represented by latitude, longitude, and altitude from sea level.

FIG. 11 is a diagram showing an example of point cloud data according to the first embodiment of the present invention.
As shown in the figure, in the information storage unit 12, as point cloud data, each coordinate point (spatial coordinate information) (X, Y, Z) measured corresponds to the light intensity of the received reflected light. attached and stored.

(2) 3D Image Conversion of Point Cloud Data Using the point cloud data acquired as described above, the repair plan formulation device 20 can generate a stereoscopic image based on the point cloud data as follows.
FIG. 12 is a diagram for explaining how the spatial coordinates are projected onto the plane to obtain the plane coordinates according to the first embodiment of the present invention.
As shown in the figure, when the coordinates of the viewpoint are (Px, Py, Pz), the repair plan formulation device 20 converts each coordinate point (X, Y, Z) of the point cloud data into a projected coordinate point (x , y).
In this manner, the repair plan formulation device 20 can generate a stereoscopic image of a landscape viewed from a certain viewpoint based on each coordinate point (X, Y, Z) of the point cloud data.
FIG. 13 is a diagram showing a display example of a stereoscopic image based on point cloud data according to the first embodiment of the present invention.
In the example shown in the figure, a stereoscopic image of a landscape seen from a viewpoint close to the passenger of a car traveling on a road is represented by a point cloud. By checking the image, the state of the tangible object can be easily grasped.

(3) Planar mapping of point cloud data Also, as described above, when projecting the spatial coordinates of the point cloud data onto a plane, display an image of the point cloud with an arbitrary display magnification when viewed from a viewpoint perpendicular to the ground. Thus, the point cloud image can be used in the same way as a normal planar map (hereinafter, the point cloud data represented on the planar map will be referred to as "point cloud map information").

(4) Acquisition of Image Data The measurement vehicle 10 acquires image data (color) by photographing the surroundings of the road with the camera 17 in addition to the point cloud data while traveling or stopping on the road.
The control unit 11 acquires the image data and the shooting time from the clock unit 17 and stores them in the information storage unit 12 in association with each other.
In addition, since the position/orientation of the camera 17 has a certain relationship with the position/orientation of the measurement vehicle 10, the control unit 11 controls the position/orientation of the camera 17 based on the information on the position/orientation of the measurement vehicle 10. 17 positions and postures are obtained.

FIG. 14 is a diagram showing an example of image data in the first embodiment of the invention.
In the illustrated example, captured image data (captured image) is stored in the information storage unit 12 in association with the position/orientation of the camera 17 at the time of capturing.
FIG. 15 is a diagram showing an image display example of image data according to the first embodiment of the present invention.
As shown in the figure, the image data represents still images or moving images captured by a normal camera or the like.

As described above, after the storage device 10 acquires the point cloud data and the image data, the repair planning device 20 transmits the point cloud data and the image data to the measurement vehicle 10 via a network or via an information recording medium. Get from

[3] Generation of data related to point cloud data (step S2)
(1) Generation of superimposed image data Based on the point cloud data and image data acquired from the measurement vehicle 10, the repair plan formulation device 20 generates superimposed image data, which is data obtained by superimposing the point cloud data on the image data.

The repair plan formulation device 20 calculates each coordinate point (X, Y, Z) is extracted.
Generation of superimposed image data will be described below with reference to FIG. Z) is projected onto the coordinate system (projected coordinate point) (x, y) of the photographed image to obtain coordinates.
In this way, the coordinates obtained by projecting each coordinate point (X, Y, Z) in the point cloud data onto the coordinate system (x, y) of the photographed image are obtained, so that each coordinate point (X, Y, Z) is associated with the projected coordinate point (x, y) projected onto the captured image.
Using this, the repair plan formulation device 20 creates an image in which the coordinates (X, Y, Z) of each corresponding coordinate point are superimposed on each projected coordinate point (x, y) on the photographed image. Data (superimposed image data) can be created.

In this way, the repair plan formulating device 20 associates the coordinate points of the point cloud data with the projected coordinate points of the photographed image (image data), and when the coordinate points of the point cloud data are specified, Corresponding image data can be extracted.

FIG. 16 is a diagram showing an example of superimposed image data in this embodiment.
In the example shown in the figure, image data (captured image) and coordinates (X, Y, Z) of each coordinate point are associated with each projected coordinate point (x, y) of the image data (captured image). It is stored in the plan formulation device 20 .
In addition, the repair plan formulation device 20 can manage each superimposed image data for each photographed image. , it is possible to easily and quickly search for the shape, current status, etc. of a tangible object to be investigated.
In addition, when the spatial coordinates are projected onto a plane, by changing the coordinates of the viewpoint, it is possible to generate an image of the superimposed image data at any display magnification when viewed from any angle. For example, it is possible to generate an image from the viewpoint of the driver, or to generate an image (bird's-eye view) from a viewpoint in the vertical direction and use it in the same way as a normal planar map.

(2) Linking of map data and point cloud data As described above, the repair plan formulation device 20 stores map data in which information on coordinates (X, Y) of map coordinate points is associated with each point. are doing. Each coordinate (X, Y) of this map coordinate point is set to be the same as or convertible to the XY coordinate of each coordinate point (X, Y, Z) of the point group data. In the following description, it is assumed that the XY coordinates of both coordinates are the same in this embodiment.

The repair plan formulation device 20 associates and stores the point cloud data and the map data based on the coordinates (X, Y) of each coordinate point.
As a result, when the map coordinate point (X, Y) is specified on the map data, the repair plan formulation device 20 can determine the coordinate point ( X, Y, Z) and displaying point cloud data including the extracted coordinate points (X, Y, Z) and each coordinate point (X, Y, Z) within a predetermined distance from the coordinate points. can be done.

Further, as described above, in the repair plan formulation system in the present embodiment, since the point cloud data and the image data are also linked, the coordinates (X, Y) of each coordinate point are used as keys, and the point cloud Data, image data, and map data can be linked, and attribute data of a tangible object located at the coordinates (X, Y) can be input by the administrator terminal 30 and linked.

In this way, the repair plan formulating device 20 manages various data related to the road management business by linking them with the coordinates (X, Y) of each coordinate point as a key. It is possible to support efficiency improvement of inspection work in, for example, function as a platform of a geographic information system (GIS: Geographic Information System).

In addition, the road administrator uses the operation unit 35 of the administrator terminal 30 to input the name, address, etc. of the tangible object as a search key, and transmits the search key to the repair plan formulation device 20. The tangible object data of the tangible object, which is the search result, can be obtained quickly, and the lead time can be shortened especially in an emergency.

[4] Generation of tangible object basic data (step S3)
(1) Extraction of Tangible Object FIG. 17 is a flow chart showing the flow of tangible object recognition operation by the repair planning system according to the first embodiment of the present invention.
Description will be made below along the diagram.

The repair plan formulation device 20 stores the point cloud data acquired from the measurement vehicle 10 in the information storage section 22 .
The control unit 21 of the repair plan formulation device 20 performs image recognition, and extracts tangible object point cloud data representing an image of a tangible object based on the point cloud data from the entire image based on the point cloud data stored in the information storage unit 22. , the type of the tangible object is identified (step S101).

In step S101, the feature amount that the control unit 21 extracts from the entire image based on the point cloud data is, for example, a SIFT (Scale-Invariant Feature Transform) feature amount or a SURF (Speeded Up Robust Feature) feature amount for local information of the object. It may be
The information storage unit 22 stores feature amount (feature point) data of an image model based on point cloud data of each type of material object in association with information on the type of material object.
The control unit 21 performs image recognition by deep learning using a neural network such as a DNN (Deep Neural Network) or a CNN (Convolutional Neural Network) using the feature amount data of the image model of each type of tangible object. may be performed.
As for this image recognition method, a general image recognition method using deep learning may be used, and detailed description thereof will be omitted.

In addition, instead of recognizing the image based on the point cloud data, the control unit 21 obtains the coordinate information of the spatial coordinate points of the point cloud that constitutes the tangible object. Tangible objects may be recognized by deep learning using feature amount data (feature amount vector) of the relative position of the coordinate information of the spatial coordinate points of the model.

In step S101, the control unit 21 performs image recognition of each tangible object using, for example, feature amount data of the tangible object such as a road, a road sign, or a street light, among images of point cloud data in a predetermined area, Point cloud data (tangible object point cloud data) that constitute roads, road signs, street lights, etc. are extracted.
Here, the extracted tangible object point cloud data includes coordinate information and latitude/longitude information of each coordinate point forming each tangible object.

During image recognition in step S101, the control unit 21 identifies the type of tangible object model whose feature amount data matches the extracted tangible object. The control unit 21 associates the information on the type of the identified material object with the material object point cloud data (step S102).

In the superimposed image data generation process described above, each coordinate point (X, Y, Z) in the point cloud data and the projected coordinate point (x, y ) are associated.
Using this, the control unit 21 identifies the projected coordinate points projected onto the captured image that are associated with the coordinate points in the tangible object point cloud data, and generates a captured image that includes the identified projected coordinate points. is extracted (step S103).
The tangible object image data extracted here includes the image of the tangible object extracted above.

Next, the control unit 21 extracts tangible object map data corresponding to the latitude and longitude information of the tangible object point cloud data of the extracted tangible objects from the map data stored in the information storage unit 22 (step S104). .
Here, for example, the control unit 21 extracts, as tangible object map data, map data of a predetermined range of the map area including the latitude and longitude information of the tangible object point cloud data.

Next, a unique tangible object ID for identifying each tangible object is assigned to the tangible object point cloud data, tangible object image data, and tangible object map data extracted above, and these tangible object point cloud data, tangible object The object image data and the tangible object map data are associated with each other (step S105).

Next, the control unit 21 creates tangible object basic data for each of the given tangible object IDs (step S106).
The information storage unit 22 of the repair plan formulation device 20 manages a plurality of tangible object basic data in the tangible object DB 221 .
Further, the information storage unit 22 stores each tangible object basic data in association with the tangible object point cloud data, the tangible object image data, and the tangible object map data associated with the same tangible object ID.
With this, the operation ends.

At the stage of step S106, among the items of the tangible object basic data, each item other than the tangible object ID is blank.

In this way, the repair plan formulation device 20 associates the tangible object basic data, the tangible object point cloud data, the tangible object image data, and the tangible object map data with each other. It becomes possible to comprehensively manage map information indicating priorities, images, and installation positions.

[5] Determination of damage rank (step S4)
FIG. 18 is a flow chart showing the flow of damage rank determination operation by the repair planning system according to the first embodiment of the present invention.
Description will be made below along with this figure.

First, the control unit 21 of the repair plan formulation device 20 converts the latitude and longitude information of the tangible object point cloud data associated with the tangible object basic data into tangible position information of the tangible object that is part of the tangible object basic data. Record in the object DB 221 (step S201).
The latitude and longitude information of the tangible object point cloud data is all or part (representative values) of the coordinate information of the point cloud forming the tangible object point cloud data, or the associated latitude and longitude information.

Next, the control unit 21 of the repair plan formulation device 20 extracts the tangible object point cloud data associated with a given tangible object ID, and based on the coordinate information of the extracted tangible object point cloud data, size information is calculated (step S202).
The control unit 21 records the calculated tangible object size information in the tangible object DB 221 as one item of the tangible object basic data.
The content of the size information calculated here may differ according to the type of material object.
For example, if the tangible object is a road, the control unit 21 calculates the length or area of the road as size information based on the coordinate information of the point group that constitutes the road in that section.

Next, the control unit 21 determines the relative positions of the tangible objects based on the coordinate information of the extracted tangible object point cloud data. Here, the control unit 21 refers to the tangible object DB 221 to determine whether or not there is another tangible object within a predetermined distance of a certain tangible object, and if it exists, extracts the tangible object ID (step S203). ).
The control unit 21 records the tangible object ID of the other detected tangible object within the predetermined distance in the tangible object DB 221 as one item of the tangible object basic data in association with the tangible object ID of the judgment target tangible object. .
For example, in step S203, the control unit 21 determines whether or not there is another tangible object including a point group located within 100 m from the coordinate information of the point group at the center (center of gravity) or end of a tangible object. do.

Next, the control unit 21 calculates a damage index for each tangible object based on the tangible object point cloud data, the tangible object image data, and the like (step S204).
For example, in step S204, the control unit 21 may calculate MCI (Maintenance Control Index) and/or IRI (International Roughness Index), which are generally used in pavement road condition surveys, as the damage index.

MCI is quantitatively evaluated by road surface property values of "crack rate", "rutting amount" and "flatness (σ)" of pavement.
For example, when calculating the MCI, the control unit 21 calculates the "crack rate" based on the tangible object image data. Specifically, the control unit 21 recognizes and traces the pavement crack image represented in the tangible object image data of the pavement surface, creates a crack deformation diagram, and calculates the “crack rate”. For this crack image recognition, a general image recognition method using deep learning may be used, and detailed description thereof will be omitted.
For example, the control unit 21 calculates the "rutting amount" and the "flatness (σ)" based on the tangible object point cloud data. Specifically, based on the tangible object point cloud data of the paved surface, the control unit 21 cuts the cross-sectional surface of the paved surface at predetermined intervals, and based on the shape of the cross-sectional surface, "ruts" Calculate the amount of excavation. In addition, the control unit 21 cuts the cut surface of the paved surface in the longitudinal direction at predetermined intervals (for example, every 100 m) based on the tangible object point cloud data of the paved surface, and based on the shape of the cut surface in the longitudinal direction to calculate the “flatness (σ)”.

The control unit 21 calculates the IRI based on the calculated "flatness (σ)".
Although Formula 1 below is used as a formula for calculating IRI, it is only an example, and other formulas may be used.
IRI=1.33σ+0.24 (Formula 1)

Next, the control unit 21 refers to the damage rank TB 222 to determine whether each tangible object is damaged based on the calculated damage index, and determines the damage rank (step S205).
This completes the damage rank determination operation.

As a method of evaluating the damage rank, for example, the control unit 21 adopts the higher damage rank among the plurality of damage indices for the damage index of each tangible object in the tangible object DB 221. A damage rank that satisfies any condition is adopted.
In the damage rank TB222 shown in the example of FIG. 7, for example, in the case of a tangible object with an MCI of "1" and an IRI of "5", the MCI corresponds to "less than 2" and can be evaluated as a damage rank of "A". , IRI corresponds to "3 or more and less than 8", so the damage rank can be evaluated as "C". In this case, the control unit 21 makes a final decision with "A", which is the higher damage rank.

As another method of evaluating the damage rank, for example, the control unit 21 adopts the lower damage rank among the plurality of damage indexes for each tangible object damage index in the tangible object DB 221, that is, A damage rank that satisfies all conditions of multiple damage indices is adopted.
In the damage rank TB222 shown in the example of FIG. 7, for example, in the case of a tangible object with an MCI of "1" and an IRI of "5", the MCI corresponds to "less than 2" and can be evaluated as a damage rank of "A". , IRI corresponds to "3 or more and less than 8", so the damage rank can be evaluated as "C". In this case, the control unit 21 makes a final decision with "C", which is the lower damage rank.

The road administrator accesses the repair plan formulation device 20 using the administrator terminal 30 and sets in advance which of the higher and lower damage ranks the control unit 21 determines as the final damage rank. be able to.
When the road administrator strongly considers the risk of an accident due to damage to a tangible object, the administrator terminal 30 is used to set the higher damage rank to determine the occurrence of an accident. It is possible to prevent this.
On the other hand, when the road administrator considers that the risk of an accident due to damage to a tangible object is not so high, the administrator terminal 30 is used to set the lower damage rank to be determined. It is possible to formulate an appropriate repair plan so as to prioritize the repair of other tangible objects that require maintenance.

[6] Registration/Update of Tangible Basic Data (Step S5)
(1) Registration/update of tangible object basic data by the road administrator As described above, in determining the repair priority rank (step S4), "location information of tangible objects", ""sizeinformation","other tangible objects within a predetermined distance", and "damage index and damage rank" are registered.
In addition, the road administrator can use the administrator terminal 30 to access the tangible object DB 221 managed by the repair plan formulation device 20 to register or update some items of the tangible object basic data.
FIG. 19 is a flow chart showing the flow of registration/update operation of tangible object basic data by the road administrator in the repair planning system according to the first embodiment of the present invention.
Description will be made below along with this figure.

First, the road administrator operates the operation unit 35 of the administrator terminal 30 to input information (registration update request) requesting registration or update of tangible object basic data (step S301).
The communication unit 33 of the administrator terminal 30 transmits a registration update request for the input tangible object basic data to the repair plan formulation device 20 (step S302).

When the communication unit 23 of the repair plan formulation device 20 receives the registration update request for the tangible object basic data from the administrator terminal 30, the control unit 21 sends the tangible object basic data registration or update target tangible object designation request. Screen information is extracted from the information storage unit 22, and the communication unit 23 transmits the extracted screen information to the administrator terminal 30 (step S303).

When the communication unit 33 of the administrator terminal 30 receives the screen information for specifying the tangible object from the repair plan formulation device 20, the display unit 34 displays the received screen information (step S304).
The screen information for specifying a tangible object includes, for example, a map based on tangible object map data associated with the latitude and longitude information of the tangible object point cloud data.

The road administrator uses the operation unit 35 to designate a tangible object to be registered in the tangible object basic data (step S305).
For example, the road administrator uses the operation unit 35 to move the cursor to the position of the tangible object on the map displayed on the display unit 34, and the tangible object to be registered or updated in the tangible object basic data this time. Specify (position of).

The administrator terminal 30 transmits information specifying the tangible object specified by the road administrator (tangible object specification information) to the repair plan formulation device 20 (step S306).
Here, the tangible object designation information may be latitude and longitude information associated with the tangible object designated above.

When the communication unit 23 of the repair plan formulation device 20 receives the tangible object designation information from the administrator terminal 30, the control unit 21 acquires the tangible object basic data of the tangible object corresponding to the tangible object designation information from the tangible object DB 221. The communication unit 23 transmits the extracted tangible object basic data to the administrator terminal 30 (step S307).
For example, when the tangible object designation information is latitude and longitude information, the control unit 21 refers to the tangible object DB 221 to determine the tangible object basic information of the tangible object whose latitude and longitude information is recorded as the position information of the tangible object. Extract data.

When the communication unit 33 of the manager terminal 30 receives the tangible object basic data from the repair plan formulation device 20, the display unit 34 displays the received tangible object basic data (step S308).
The road administrator uses the operation unit 35 to register unregistered items of the tangible object basic data displayed on the display unit 34, or to update registered items (step S309).
For example, the road administrator uses the operation unit 35 to input each item of tangible object basic data such as the date of manufacture of the tangible object, the last repair date of the tangible object, and the unit price for repairing the tangible object.

The date of manufacture of the tangible object and the date of last repair input here are used when the repair plan formulation device 20 determines the repair priority rank.
That is, the repair plan formulating device 20 determines how much time has elapsed based on the date of manufacture for a tangible object that has never been repaired, and the last repair date for a tangible object that has been repaired. to determine the repair priority rank.
The repair plan formulation device 20 determines that there is a high possibility that damage has occurred to a tangible object that has been in service for a long time even if the tangible object has the same damage rank. Formulate a repair plan so that repairs will be carried out in time.

The input repair unit price is, for example, a repair cost per unit area or per unit length.
For example, the repair plan formulation device 20 calculates the repair cost of each tangible object based on the following formula (2).
(Tangible item repair cost) = (Repair unit price) x (Tangible item size information)
... formula (2)

The communication unit 33 of the administrator terminal 30 transmits the information of each item of the input tangible object basic data to the repair plan formulation device 20 (step S310).

When the communication unit 23 of the repair plan formulation device 20 receives the information of each item of the tangible object basic data from the administrator terminal 30, each item of the tangible object basic data of the tangible object DB 221 corresponding to each received item. is registered or updated (step S311).
This completes the operation of registering/updating the tangible object basic data by the road administrator.

As described above, the road administrator uses the administrator terminal 30 to input each item of the date of manufacture of the tangible object and the date of last repair, thereby appropriately determining the repair priority rank. An appropriate repair plan can be formulated.
In addition, the road administrator can easily calculate the repair cost of the tangible object by inputting the repair unit price of the tangible object using the administrator terminal 30 .

(2) Registration of Repair Request Information by Users A user of a tangible object can make a repair request to the road administrator for the tangible object that he/she is using.
For example, if the user hears an abnormal noise while driving on the road, the pavement of the road may be damaged. make a request for repair of

The user uses the operation unit 45 to input each item of the repair request information into the input fields displayed on the display unit 44 (step S404).
For example, the user may input the type of tangible item "road pavement", the location of the tangible item "near Shinjuku entrance on Route 4 Shinjuku Line", and the reason for needing repair "pothole". With respect to the position of , a map based on tangible object map data may be displayed on the screen information for registering the repair request information, and the corresponding position may be specified using the operation unit 45 such as a mouse.

The communication unit 43 of the user terminal 40 transmits information indicating each item of the input repair request information to the repair plan formulation device 20 (step S405).
At this time, the information of each item of the repair request information transmitted by the user terminal 40 is the information input by the user and position information such as latitude and longitude corresponding to the position on the map specified by the user.

When the communication unit 23 of the repair plan formulation device 20 receives the information of each item of the repair request information, the control unit 21 refers to the tangible object DB 221 and selects the corresponding tangible object based on the received position information. To detect. Then, the control unit 21 registers the received information of each item in the tangible object DB 221 as repair request information in association with the tangible object ID of the detected tangible object (step S406).
In addition, the control unit 21 increases the number of registrations by 1 according to the registration of each item of the repair request information this time, and registers it in the tangible object DB 221 as repair request information (step S407).
This completes the operation of registering the repair request information.

FIG. 22 is a sequence chart showing the flow of display operation of damaged tangible object screen information by the repair planning system according to the first embodiment of the present invention.
Description will be made below along with this figure.

First, the road administrator operates the operation unit 35 of the administrator terminal 30 to input search conditions for requesting acquisition of damage rank screen information to the repair plan formulating device 20 (step S501).
Specifically, the road administrator uses the operation unit 35 to input position information, damage rank, or the like of a tangible object to be displayed in the damage rank screen information as search conditions.
For example, position information such as "Minato-ku, Tokyo" is set as a search condition.
Also, for example, it is a four-grade evaluation from damage rank A to D, where A is the most severe damage, B and C are light in order of damage, and D is no damage. A search condition such as "damage rank B or higher" is set.

The communication unit 33 of the administrator terminal 30 transmits the input search conditions to the repair plan formulation device 20 (step S502).

When the communication unit 23 of the repair plan formulation device 20 receives the search conditions, the control unit 21 refers to the tangible object DB 221 and the like, and searches for tangible objects that match the search conditions (position information and damage rank) ( step S503).

Next, the control unit 21 executes a search process, extracts tangible objects that match the search conditions, and generates a list showing the extracted tangible objects (step S504).
This list consists of physical object basic data for each extracted physical object.

Next, the control unit 21 determines a repair priority rank indicating which of the plurality of tangible objects should be preferentially repaired for the plurality of tangible objects shown in the list, and determines the repair priority rank. The tangible objects are rearranged in order of repair priority rank (step S505).
An example of the method for determining the repair priority rank will be described below.

First, the control unit 21 ranks the tangible objects in descending order of the determined damage rank. At this time, for tangible objects of the same damage rank, the control unit 21 sorts the unrepaired tangible object in descending order of the elapsed time from the date of manufacture and the last repair date of the repaired tangible object to the present. rank.

In addition, the control unit 21 refers to the repair request information in the tangible object basic data of each tangible object, and raises the repair priority rank of the tangible object for which the repair request information is registered a large number of times.
For example, if the number of repair request information registrations is 10 or more, the rank will be increased by "3", if it is 5 to 9 times, it will be increased by "2", and if it is 1 to 4 times, it will be increased by "1". The greater the number of times, the greater the range of increase in the repair priority rank.
In this manner, the control unit 21 raises the repair priority rank of a tangible object for which repair has been requested frequently, so that an appropriate repair plan can be implemented so that the tangible object for which the user has discovered damage is preferentially repaired. It becomes possible to formulate

Further, the control unit 21 refers to the position information in the tangible object basic data of each tangible object, and raises the repair priority rank of the tangible object within a predetermined distance from the tangible object with a high damage rank.
For example, for a tangible object within a predetermined distance from a tangible object with damage rank A, the repair priority rank is increased by “3”, and for a tangible object within a predetermined distance from a tangible object with damage rank B, the repair priority rank is increased by “1”. Thus, the higher the damage rank of the tangible object within a predetermined distance, the greater the range of increase in the repair priority rank.
Also, for example, for tangible objects adjacent to damage rank A tangible objects, the repair priority rank is increased by “3”, and for tangible objects within 100m from damage rank A tangible objects, the repair priority rank is increased by “1”. As shown in , even if the damage rank is the same, the closer the tangible object, the larger the increase in the repair priority rank.
Also, for example, for roads within 100m from a road with damage rank A, the repair priority rank is increased by "3", and for bridge piers within 100 meters from the road with damage rank A, the repair priority rank is increased by "1". Even if the damage rank and the distance are the same, the tangible object of the same type has a greater range of increase in the repair priority rank than the tangible object of a different type.
In this way, the control unit 21 raises the repair priority rank of other tangible objects adjacent to a tangible object with a high repair priority rank, thereby collectively performing repair work on a plurality of tangible objects. As a result, it is possible to shorten the construction period and improve the efficiency of the construction work.

Next, the control unit 21 refers to the tangible object basic data of the tangible objects extracted by matching the search conditions, and based on the position information (latitude and longitude information) of the matching tangible objects, determines the positions of the tangible objects. A damaged tangible object map data is generated by synthesizing the indicated image (mark Mk, which will be described later) on the map data (step S506).

Next, the control unit 21 synthesizes the list with the damaged tangible object map data to generate screen information of tangible objects that may be damaged (damaged tangible object screen information) (step S507).
The communication unit 23 transmits the generated damaged tangible object screen information to the administrator terminal 30 (step S508).

When the communication unit 33 of the administrator terminal 30 receives the damaged tangible object screen information, the display unit 34 displays the received damaged tangible object screen information (step S509).
FIG. 23 is a diagram showing an example of damaged tangible object screen information according to the first embodiment of the present invention.
In the illustrated example, a mark Mk is displayed at the position of the tangible object on the map Mp. In order to distinguish each mark Mk, each mark Mk is numbered.
Further, the display unit 34 displays a characteristic display according to the damage rank for the tangible object itself on the map Mp on which each mark Mk of the damaged tangible object screen information is displayed. In the illustrated example, the tangible objects on the map Mp are colored differently according to their damage ranks. By confirming the color corresponding to each damage rank, the road administrator can easily grasp the damage rank of each tangible object on the map Mp.
Also, in the damaged tangible object screen information, a list Lt of tangible objects that match the search conditions and may be damaged is displayed.
List Lt shows a plurality of tangible objects in order of repair priority rank determined as described above. That is, the higher the tangible item listed on the list Lt, the higher the priority of repair.
The list Lt displays the number assigned to the mark Mk, the damage rank, the damage index, and the numerical values associated therewith for each tangible object.
Numerical values associated with the damage index are, for example, average crack length, maximum crack length, average rut depth, or maximum rut depth.
The road administrator can sort (arrange) the tangible object basic data displayed in the list Lt by operating the operation unit 35 and inputting sort conditions. For example, the damage rank, the damage index, and the numerical value associated with the damage index can be sorted in ascending or descending order.
Furthermore, a repair plan formulating button is provided on the damaged tangible object screen information. As will be described later, the road administrator operates the operation unit 35 and presses (designates) a repair plan formulating button to create a repair plan for the tangible objects listed in the damaged tangible object screen information list Lt. can be formulated.

In addition, in the illustrated example, a part of the damage rank TB222 is displayed in the damaged tangible object screen information.
By confirming a part of the damage rank TB222, the road administrator can easily grasp the method of determining the repair priority rank.

The mark Mk of the damaged tangible object screen information is associated with the tangible object ID of the tangible object that matches the search condition.
When the road administrator operates the operation unit 35 of the administrator terminal 30 and clicks the mark Mk to specify it, the display unit 34 displays the list Lt displayed in the list Lt under the control of the control unit 31. The tangible object basic data portion of the tangible object ID associated with the designated mark Mk is displayed in a distinctive manner, such as by changing the color of the tangible object basic data, to distinguish it from other tangible object basic data (step S510).

As described above, the manager terminal 30 displays information about tangible objects that match the search conditions input by the road manager on the damaged tangible object screen information. can be easily confirmed, and it becomes possible to formulate a repair plan for tangible objects efficiently.
In particular, on the map Mp of the damaged tangible object screen information, tangible objects are displayed in different colors for each damage rank, for example, so that the road administrator can easily grasp the degree of damage to each tangible object. can.

In addition, since the tangible objects are displayed in order of repair priority rank on the list Lt of the damaged tangible object screen information, the road administrator can easily determine which tangible object should be repaired preferentially. becomes possible.

In the example described above, "positional information" and "damage rank" were used as search conditions, but this is merely an example, and the road administrator may search using other search conditions.

(2) Formulation of Repair Plan As described above, the administrator terminal 30 displays the damaged tangible object screen information representing tangible objects that match the search conditions specified by the road administrator.
By pressing the repair plan formulating button of the damaged tangible object screen information, the road administrator formulates a repair plan for the tangible objects listed in the damaged tangible object screen information list Lt as follows. It can be carried out.
24 and 25 are sequence charts showing the flow of repair plan formulation operation by the repair plan formulation system according to the first embodiment of the present invention.
Description will be made below along with this figure.

First, when the road administrator operates the operation unit 35 of the administrator terminal 30 and presses the repair plan formulation button, the communication unit 33 transmits a repair plan formulation request to the repair plan formulation device 20 (step S601). ).

When the communication unit 23 of the repair plan formulation device 20 receives the repair plan formulation request from the administrator terminal 30, the control unit 21 displays screen information for inputting repair plan formulation conditions (formulation condition input screen information ) from the information storage unit 22, and the communication unit 23 transmits the extracted formulation condition input screen information to the administrator terminal 30 (step S602).

When the communication section 33 of the administrator terminal 30 receives the formulation condition input screen information, the display section 34 displays the received formulation condition input screen information (step S603).
FIG. 26 is a diagram showing an example of screen information for inputting formulation conditions according to the first embodiment of the present invention.
In the illustrated example, the screen information for inputting formulation conditions is provided with an input column for total budget, a column for specifying a tangible object to be repaired, and an input column for repair unit price.

The road administrator operates the operation unit 35 to input the value of the total budget of the repair plan in the total budget input field (step S604).

Next, the road administrator operates the operation unit 35 to designate the tangible object to be repaired in the designation column of the tangible object to be repaired (step S605).
As a method of specifying this tangible object, for example, a mark Mk on the map Mp may be selected, a target tangible object on the list Lt may be selected, or the tangible object ID of the target tangible object may be selected. may be entered.

Next, the road administrator operates the operation unit 35 to enter the repair unit price of the specified tangible object to be repaired in the repair unit price input field (step S606).
In this example, the repair unit price is input by the road administrator, but the control unit 21 of the repair plan formulating device 20 may extract a value that has already been registered in the tangible object DB 221 .

The communication unit 33 transmits each information of the input total budget of the repair plan, the tangible object ID of the specified tangible object, and the repair unit price to the repair plan formulating device 20 (step S607).

When the communication unit 23 of the repair plan formulation device 20 receives each information of the total budget value of the repair plan, the tangible object ID of the tangible object, and the repair unit price from the administrator terminal 30, the control unit 21 The "value of the total budget" is divided by the above-mentioned "repair unit price" to calculate the value of the "size of a repairable tangible object (repairable size)" (step S608).
For example, if the total budget for repairing road pavement is "one million yen" and the unit price for repairing road pavement is "10,000 yen per ^square meter," the control unit 21 calculates (1 million yen)/(10,000 yen). Yen/m ² ) = 100 m ² . This indicates that it is possible to repair road pavement with an area of ^100m2 .

Next, the control unit 21 extracts the size information of the tangible object included in the tangible object basic data associated with the specified tangible object ID from the tangible object DB 221 (step S609).

Next, the control unit 21 compares the extracted “size information value of the tangible object” with the calculated “repairable size value”, and the “value of the size information of the tangible object” is larger. It is determined whether it is a value (step S610).

As a result of the above comparison, if the control unit 21 determines that the "value of the size information of the tangible object" is a larger value (step S610/Yes), the control unit 21 adds the calculated "repairable size" to calculate the value of the cost (repair plan cost) required for the repair (step S611), and as the size of the tangible object that can be repaired at the repair plan cost (repair plan size information) , the "repairable size value" is adopted (step S612), and the process proceeds to step S615.

On the other hand, if the control unit 21 determines that the "repairable size value" is larger as a result of the comparison (step S610/No), the extracted "tangible item is multiplied by the "size information value" to calculate the value of the repair plan cost (step S613), and the above "size information value of the tangible object" is adopted as the repair plan size information (step S614).

Next, the communication unit 23 transmits the repair plan cost and repair plan size information to the administrator terminal 30 (step S615).

When the communication unit 33 of the administrator terminal 30 receives the repair plan cost and repair plan size information from the repair plan formulation device 20, the control unit 31 adds the received repair plan cost and repair plan size information to the Repair plan screen information is generated using the input repair plan total budget value and repair unit price, and the display unit 34 displays the generated repair plan screen information (step S616).

FIG. 27 is a diagram showing an example of repair plan screen information according to the first embodiment of the present invention.
The repair plan screen information displays the total budget value of the repair plan, repair unit price, repair plan cost, and repair plan size information.
In the illustrated example, the repair plan screen information displays "10 million yen" as the value of the total budget for road pavement and "5 million yen" as the value of the repair plan cost. From this, it is shown that "5,000,000 yen" is still left as the budget out of the total budget, and that the remaining amount can be used for the repair plan of other tangible objects.
The repair plan screen information also displays that the repair unit price for road pavement is "10,000 yen per 1 ^m2 ".
Further, in ^the repair plan screen information, "50 m ² " is displayed as the repair plan size of the road pavement. This indicates that repair work can be carried out.
Since the road pavement to be repaired in this example can be entirely repaired within the total budget of the repair plan, "size information=repairable size=repair plan size=50 m ² ".

By checking the content of the repair plan screen information, the road administrator can easily grasp the cost required for repairing the tangible objects displayed at the top of the list Lt, the size that can be repaired, etc., and formulate a repair plan. can be easily performed.
In addition, the road administrator can view the repair plan screen information to grasp the remaining amount of the budget for the repair plan. By causing the repair plan formulation system to repeatedly execute the repair plan formulation operation until the amount becomes equal to or less than the amount of , it is possible to easily formulate a repair plan related to the total budget.

(Summary of the first embodiment)
