The damage investigation system 1 includes a server device 10 including a database 11 and a terminal 100. The damage investigation system 1 includes a processor, and the processor realizes each function. For example, the processor of the damage investigation system 1 includes a first processor 12 (see FIG. 2) included in the server device 10 and a second processor 112 (see FIG. 6) included in the terminal 100. In the case shown in FIG. 1, the damage investigation system 1 including two terminals 100 is described, but the damage investigation system 1 can include one or more terminals 100.

The server device 10 and the terminal 100 are connected to a network NW such as the Internet, and the server device 10 and the terminal 100 can communicate with each other.

Investigators conducting investigations during disasters carry the terminal 100 with them. The server device 10 is installed in a remote location different from the place where the survey is conducted, and transmits the requested survey preparation information to the terminal 100 in response to a request from the terminal 100 to transmit survey preparation information.

The terminal 100 is equipped with a display unit (for example, a display) 120, and the investigator always carries the terminal 100 while conducting an investigation, and the survey work range and surveyed range displayed on the display unit 120 of the terminal 100 You can conduct an investigation while checking information such as.

Next, the server device 10 included in the damage investigation system 1 will be explained.

The server device 10 functions as a management server for conducting investigations. The server device 10 has a database 11 that stores circumferential shape information CO (vertex data indicating the apex of the house in latitude and longitude) of the house to be investigated in association with a house ID (identification). Based on the house ID, the server device 10 provides the outer circumferential shape information CO of the house corresponding to the house ID to the terminal 100 via the network NW. Further, the server device 10 may receive the results of the investigation conducted by the investigator from the terminal 100 and store them in the database 11.

FIG. 2 is a diagram showing an example of the hardware configuration of the server device 10.

The server device 10 includes a database 11, a first processor 12, a communication interface 14, and a computer readable medium 16.

The database 11 is stored in an auxiliary storage device. The database 11 stores data including outer circumferential shape information CO and map information MP. The outer circumferential shape information CO is composed of vertex data indicating the outer circumferential shape of the house to be investigated, and the vertex data is expressed by longitude and latitude coordinates indicating the position of the vertex. Map information MP includes neighborhood information and topographical information. The neighborhood information is information CO on the outer periphery of houses surrounding the house to be investigated. Furthermore, the topographical information is information regarding the topography around the house that is the object of investigation, and includes positional information of places around the house that are inaccessible to investigators, such as mountains, rivers, cliffs, oceans, and lakes.

FIG. 3 is a diagram showing an example of the storage configuration of the outer circumferential shape information CO stored in the database 11.

A house ID is given to each house as an identification code for identifying each house. The database 11 stores the house ID and the apex data of the house, which is the outer circumferential shape information CO, in association with each other. The vertex data consists of longitude and latitude coordinates of the vertex of the house. In the example shown in FIG. 3, the outer circumferential shape information CO of the house IDs "○○××△△" and "△△△△△△" is shown, and information on other house IDs is omitted. ing.

For example, the vertex data that is the outer circumferential shape information CO of the house ID "○○ expressed. In addition, the vertex data that is the outer circumference shape information CO of the house ID "△△△△△△" is composed of the first to fourth vertices, and the first to fourth vertices are the longitude and latitude coordinates. expressed. In addition, in the above example, a case was explained in which the outer circumferential shape of the house is represented by four vertices as the outer circumferential shape information CO, but the outer circumferential shape information CO is not limited to four vertices, and may represent the outer circumferential shape of the house. It can be made up of multiple vertices.

FIG. 4 is a diagram illustrating a specific example of map information MP stored in the database 11.

The map information MP shown in FIG. 4 is neighborhood information, and has outer circumferential shape information CO of other structures around the house to be investigated. The house ID “○○××△△” explained in FIG. It is data. In this way, the neighborhood information of the map information MP is composed of the outer circumferential shape information CO of a group of houses in a predetermined area. Note that in the case of Japan, map information MP including such outer circumferential shape information CO (vertex data) can be obtained from basic map information provided by the Geospatial Information Authority of Japan, for example. Alternatively, such map information MP can also be obtained from the OpenStreetMap database.

Returning to FIG. 2, the first processor 12 is composed of a CPU (Central Processing Unit). Further, the first processor 12 may include a GPU (Graphics Processing Unit). The first processor 12 is connected via a bus 13 to a computer readable medium 16 and a communication interface 14 . The first processor 12 can implement various functions by executing a dedicated program stored in the computer readable medium 16.

FIG. 5 is a functional block diagram showing the functions realized by the first processor 12.

The first processor 12 constitutes an information request receiving section 12A and an information transmitting section 12B.

The information request receiving unit 12A receives a request to send investigation preparation information from the terminal 100. Here, the survey preparation information is information for the survey of the house to be surveyed, for example, the outer circumferential shape information CO of the house to be investigated, or the survey work range calculated from the outer circumferential shape information CO of the house to be investigated. . Therefore, the request to send survey preparation information includes a house ID that identifies the house that is the target of the survey, and the outer circumferential shape information CO or survey work range corresponding to the house ID is transmitted in response to the request. . Specifically, first, the investigator inputs the ID of the house to be investigated into the terminal 100. Then, the terminal 100 transmits, for example, a request for transmission of survey preparation information including the input house ID to the server device 10. The server device 10 receives a request to send investigation preparation information from the terminal 100.

The information transmitting unit 12B transmits survey preparation information to the terminal 100 in response to the survey preparation information transmission request. For example, the information transmitter 12B reads the outer circumference shape information CO corresponding to the house ID included in the received survey preparation information transmission request from the database 11, and sends the read outer circumference shape information CO to the terminal 100 that sent the transmission request. Send. Note that, when the map information MP is stored in the database 11, the information transmitting unit 12B also transmits the map information MP corresponding to the outer circumferential shape information CO to be transmitted.

Returning to FIG. 2, the computer-readable medium 16 includes a memory that is a main storage device and a storage that is an auxiliary storage device. The computer readable medium 16 may be, for example, a semiconductor memory, a hard disk drive (HDD) device, a solid state drive (SSD) device, or a combination of these. The computer readable medium 16 stores various programs and data including an image processing program and a display control program.

The communication interface 14 is a communication unit that performs wireless or wired communication with the terminal 100.

As explained above, the server device 10 functions as a management server, and provides the outer circumferential shape information CO and map information MP of the house to be investigated to the terminal 100 via the network NW.

<Terminal>
Next, the terminal 100 included in the damage investigation system 1 will be explained.

The terminal 100 is carried by the investigator during the investigation. The investigator conducts the investigation while checking the investigation work range and the researched range displayed on the display unit 120 (FIG. 6) of the terminal 100. Therefore, the investigator can conduct the investigation while being guided by the investigation work range and the researched range displayed on the display unit 120. A research support application program is installed on the terminal 100, and various processes are performed by executing the research support application program. The terminal 100 also outputs information on the position and orientation of the terminal itself, and the surveyed range of the survey work range is specified based on the output position and orientation information.

FIG. 6 is a diagram showing an example of the hardware configuration of the terminal 100.

The terminal 100 includes a second processor 112, a computer readable medium (memory) 116, a communication interface 114, a camera 134, a display section 120, and a position information output section 140.

The second processor 112 is composed of a CPU (Central Processing Unit). Further, the second processor 112 may include a GPU (Graphics Processing Unit). The second processor 112 is connected to a computer readable medium 116 , a communication interface 114 , a camera 134 , a display 120 , and a location information output 140 via a bus 113 . The second processor 112 can implement various functions by executing a dedicated program (research support application program) stored in the computer-readable medium 116.

FIG. 7 is a functional block diagram showing the functions realized by the second processor 112.

The second processor 112 includes an information request transmitting section 112A, an information receiving section 112B, an investigation work range calculation section 112C, an investigated range identification section 112D, and a display control section 112E.

The information request transmitter 112A transmits a request to transmit investigation preparation information to the server device 10. Specifically, when starting the survey, the surveyor inputs the ID of the house to be surveyed using the input unit of the terminal 100. Note that in the terminal 100, the display section 120 is configured with a touch panel and also functions as an input section. The information request transmitter 112A transmits a request to transmit survey preparation information corresponding to the input house ID via the communication interface 114.

FIG. 8 is a diagram showing an example of a user interface displayed on the display unit 120 of the terminal 100 when starting an investigation.

The terminal 100 executes the research support application program, and the display control unit 112E displays a user interface 121 as shown in FIG. 8 on the display unit 120.

The user interface 121 shows the team in charge of the investigation (see reference numeral 121A). Further, the user interface 121 shows the survey implementation date (see reference numeral 121B). The user interface 121 also shows an investigator who conducts the investigation (see reference numeral 121C). Further, the user interface 121 displays a map of the house to be investigated (see reference numeral 121D). The user interface 121 also includes a list of surveyed houses (see reference numeral 121F). The surveyed house list shows detailed information such as the structure, building type, and address of each house. Further, the survey house list has a survey start button S for each house. When investigating a house, the investigator taps the investigation start button S of the corresponding house and inputs the house ID of the house to be investigated. Thereby, the terminal 100 acquires the house ID of the house to be surveyed, and the information request transmitting unit 112A transmits a request for transmitting survey preparation information corresponding to the house ID to the server device 10.

As described above, in this example, the user interface 121 is displayed on the display unit 120 of the terminal 100, a house to be investigated is selected, and the house ID is accepted. Thereby, the investigator can accurately and easily input the house ID into the terminal 100, and can reliably acquire the investigation preparation information of the house to be investigated.

Returning to FIG. 7, the information receiving unit 112B receives survey preparation information from the server device 10. Specifically, the information receiving unit 112B receives the outer circumferential shape information CO or the outer circumferential shape information CO and the map information MP transmitted by the server device 10 via the communication interface 114. The outer circumferential shape information CO received by the information receiving unit 112B is the outer circumferential shape information CO corresponding to the house ID of the house to be investigated specified by the investigator.

The survey work range calculation unit 112C calculates the survey work range for the survey of the house to be surveyed, based on the outer circumferential shape information CO received by the information receiving unit 112B. The investigation work range calculation unit 112C calculates the range to be investigated from the apex data of the outer circumference shape included in the outer circumference shape information CO. Specifically, the survey work range calculation unit 112C calculates the survey work range along a side (corresponding to a wall of a house) formed by connecting adjacent vertices.

The surveyed range specifying unit 112D identifies the surveyed range in which the survey has been conducted within the survey work range based on the location information where the survey is estimated to have been conducted. Specifically, the surveyed range identifying unit 112D identifies the surveyed range of the survey work range based on information output from the location information output unit 140 of the terminal 100. When the terminal 100 is located within the investigation work range, the investigator carrying the terminal 100 is also located within the investigation work range, and when the investigator is located within the investigation work range, the investigator is at that position. It can be assumed that an investigation is being conducted. Therefore, the surveyed range identification unit 112D can identify the surveyed range based on the location information of the terminal 100.

The display control unit 112E can display various information needed by the investigator in conducting the investigation. For example, the display control unit 112E displays the survey work range and the surveyed range. In this way, by displaying the survey work range and the surveyed range on the display unit 120 of the terminal 100 carried by the surveyor, the surveyor can comprehensively survey the survey work range of the house to be surveyed. be able to.

Returning to FIG. 6, the computer-readable medium 116 includes a memory that is a main storage device and a storage that is an auxiliary storage device. Computer-readable medium 116 may be, for example, a semiconductor memory, a hard disk drive (HDD) device, a solid state drive (SSD) device, or a combination of these.

The communication interface 114 is a communication unit that performs wireless communication or wired communication.

The camera 134 acquires a photographed image of the subject through the operation of the investigator. For example, the camera 134 captures images of the exterior walls and damage of the house being investigated.

The display unit 120 is composed of a display and displays information possessed by the terminal 100. For example, the display section 120 displays the investigation work range calculated by the investigation work range calculation section 112C under the control of the display control section 112E. Further, the display unit 120 displays the surveyed range specified by the surveyed range specifying unit 112D under the control of the display control unit 112E. Further, the display section 120 includes a touch panel and also functions as an input section.

The position information output unit 140 outputs information regarding the position and orientation of the terminal 100. The position information output unit 140 includes a GPS (Global Positioning System) receiver 122, an atmospheric pressure sensor 124, an acceleration sensor 126, a gyro sensor 128, a timer 130, and a counter 132.

The GPS receiver 122 acquires location information including the longitude and latitude of the terminal 100. The terminal 100 can acquire the position of the terminal 100 based on the position information acquired by the GPS receiver 122. Atmospheric pressure sensor 124 detects the atmospheric pressure at terminal 100 . The terminal 100 can obtain the altitude of the terminal 100 based on the atmospheric pressure detected using the atmospheric pressure sensor 124.

The acceleration sensor 126 can detect the tilt, parallel movement, speed, and displacement of the terminal 100. The gyro sensor 128 detects a roll angle representing a rotation angle about the roll axis, a pitch angle representing a rotation angle about the pitch axis, and a yaw angle representing a rotation angle about the yaw axis. The terminal 100 uses the acceleration sensor 126 and the gyro sensor 128 to obtain attitude information of the terminal 100.

The timer 130 can measure a predetermined time. For example, the timer 130 measures the time the terminal 100 stays in the survey work range.

The counter 132 can count the number of times the terminal 100 performs a predetermined operation. For example, the counter 132 counts the number of times the terminal 100 enters the investigation work range.

In the case shown in FIG. 6, an example has been described in which the position information output unit 140 includes the GPS receiver 122, the atmospheric pressure sensor 124, the acceleration sensor 126, the gyro sensor 128, the timer 130, and the counter 132. It is not limited. As will be explained later, there is no particular limitation as long as information that allows the investigator to specify what has been investigated within the scope of the investigation work can be obtained. Further, in the case shown in FIG. 6, the terminal 100 including the camera 134 has been described, but the present invention is not limited to this. If photographing is not particularly required during the investigation, it is also possible to use the terminal 100 without the camera 134.

<Damage investigation method>
Next, a damage investigation method using the damage investigation system 1 will be explained. The damage investigation method is performed by the processor of the damage investigation system executing a program, and specifically, the first processor 12 of the server device 10 and the second processor of the terminal 100 included in the damage investigation system 1. This is done by the processor 112 executing a dedicated program.

FIG. 9 is a flow diagram showing a damage investigation method using the damage investigation system 1.

First, the investigator identifies the house to be investigated and inputs the house ID into the terminal 100 (step S10). Thereafter, the information request transmitter 112A of the terminal 100 transmits a request to transmit survey preparation information including the input house ID to the server device 10 (step S11: second transmitting step).

The server device 10 receives the request to send survey preparation information sent by the information request receiving unit 12A via the communication interface 14 (step S12: first receiving step). After that, the server device 10 uses the information transmitting unit 12B to read the outer circumferential shape information CO corresponding to the request for transmitting survey preparation information from the database 11, and transmits it to the terminal 100 via the communication interface 14 (step S13: the first transmission process). In this case, if the map information MP is stored in the database 11, the map information MP may also be transmitted to the terminal 100.

The terminal 100 receives the outer circumferential shape information CO transmitted from the server device 10 by the information receiving unit 112B via the communication interface 114 (step S14: second receiving step). Thereafter, the terminal 100 uses the investigation work range calculation unit 112C to calculate the investigation work range based on the acquired outer circumferential shape information CO (step S15: calculation step). The investigator carries the terminal 100 and conducts the investigation while referring to the investigation work range displayed on the display unit 120. When an investigator is conducting an investigation, the terminal 100 acquires location information from the location information output unit 140. Based on the location information of the terminal 100 outputted by the location information output unit 140, the terminal 100 uses the investigated range identification unit 112D to identify the investigated range in which the investigation has been performed within the investigation work range (step S16: specific process). Thereafter, the terminal 100 displays the survey work range and the surveyed range on the display unit 120 by the display control unit 112E (step S17: display step). The investigator conducts the investigation covering the investigation work range while referring to the investigation work range and the researched range displayed on the display unit 120 of the terminal 100. Thereafter, the investigator inputs the investigation results (for example, damage identification results) via the input section of the terminal 100, and the terminal 100 receives the investigation results (step S18). Then, the terminal 100 transmits the received survey results, survey work range, and surveyed range to the server device 10 via the communication interface 114 (step S19).

The server device 10 receives the survey results, the survey work range, and the surveyed range via the communication interface 14, and stores the survey results, survey work range, and survey completed range in a database by associating them with the ID of the house to be surveyed. 11 (step S20).

As explained above, in the damage investigation system 1 described above, the investigation work range is calculated based on the outer circumferential shape information CO of the house to be investigated, and the calculated investigation work range is displayed. Further, based on the position information of the terminal 100, a surveyed range in which the survey has been performed is specified within the survey work range. As a result, by using the damage investigation system 1, the investigator can suppress failure to detect damage to the structure to be investigated and conduct the investigation efficiently.

Furthermore, in the damage investigation system 1, the investigation results conducted by the investigator are recorded in the database 11 along with the investigation work range and the investigation completed range. Therefore, since the investigation results, the investigation work scope, and the investigation completed range are recorded in association with each other, a third party can efficiently judge the sufficiency of the investigation results.

Note that in the above description, the steps from step S10 to step S20 are described as a series of steps, but the application of the present invention is not limited to this. For example, the OPT process (steps S11 to S14) shown in FIG. It may be possible to start an investigation. In this case, the terminal 100 temporarily stores the outer circumferential shape information CO and the map information MP in the computer readable medium (memory) 116.

Furthermore, in the above description, the server device 10 transmits the outer circumferential shape information CO (step S13) in response to the request for transmission of survey preparation information transmitted from the terminal 100 (step S11). Application of the invention is not limited to this. For example, in response to a request to send investigation preparation information sent from the terminal 100, the server device 10 may send the investigation work range. In this case, the server device 10 reads the outer circumferential shape information CO corresponding to the request for transmission of investigation preparation information from the database 11, calculates the investigation work range based on the outer circumference shape information CO, and transfers the calculated investigation work range to the terminal 100. You may also send it to

In the above embodiment, the hardware structure of the processing unit (the first processor 12 and the second processor 112) that executes various processes includes the following various processors. be. Various types of processors include CPUs (Central Processing Units) and FPGAs (Field Programmable Gate Arrays), which are general-purpose processors that execute software (programs) and function as various processing units.The circuit configuration can be changed after manufacturing.

It's okay. Further, the plurality of processing units may be configured with one processor. As an example of configuring multiple processing units with one processor, first, one processor is configured with a combination of one or more CPUs and software, as typified by computers such as clients and servers. There is a form in which a processor functions as multiple processing units. Second, there are processors that use a single IC (Integrated Circuit) chip to implement the functions of the entire system, including multiple processing units, as typified by System On Chip (SoC). be. In this way, various processing units are configured using one or more of the various processors described above as a hardware structure.

For example, a program that causes a computer to execute the above-mentioned processing steps (processing procedures), a computer-readable recording medium (non-temporary recording medium) that records such a program, or a computer that can install such a program. It is possible to apply the present invention to any case.

<Calculation of investigation work scope>
Next, the investigation work range calculated by the investigation work range calculation unit 112C of the terminal 100 will be explained in detail.

The investigation work range calculation unit 112C calculates the range to be investigated from the vertex data included in the outer circumferential shape information CO. The investigation work range calculation unit 112C calculates an investigation work range having a predetermined width L (see FIG. 10) from sides (corresponding to walls of a house) formed by connecting adjacent vertices in the vertex data. An example of the investigation work range calculated by the investigation work range calculation unit 112C will be described below. Further, the investigation work range calculated by the investigation work range calculation unit 112C, which will be described below, is displayed on the display unit 120 of the terminal 100 by the display control unit 112E.

FIG. 10 is a diagram showing an example of the investigation work range calculated by the investigation work range calculation unit 112C.

FIG. 10 shows an investigation work area 152 of a house 150. The vertex data included in the outer circumferential shape information CO of the house 150 is vertex data 154A, vertex data 154B, vertex data 154C, and vertex data 154D. Note that the vertex data 154A to 154D are composed of longitude and latitude coordinates of four vertices of a rectangular house. The investigation work range calculation unit 112C calculates an investigation work range 152 having a width L from sides formed by connecting adjacent vertices among the vertex data 154A to 154D. When investigating the house 150, the inspector enters the investigation work area 152 and conducts the investigation, thereby being able to comprehensively investigate the house 150 and suppressing failure to detect damage to the house 150. A survey can be carried out.

FIG. 11 is a diagram showing another example of the investigation work range calculated by the investigation work range calculation unit 112C. Note that the parts already described in FIG. 10 are designated by the same reference numerals, and the description thereof will be omitted.

In this example, calculation of the survey work range when the house 150 is adjacent to the neighboring house 160 will be explained. In this way, when the house 150 to be investigated is adjacent to another structure, the investigation work range calculation unit 112C also calculates the non-investigation target range 162.

The information receiving unit 112B of the terminal 100 receives the outer circumferential shape information CO and map information MP of the house 150 that is the object of investigation. The investigation work range calculation unit 112C calculates the investigation work range 152 and the non-investigation target range 162 based on the outer circumferential shape information CO and the map information MP. Here, the map information MP includes neighborhood information that is information on structures near the house 150. In the case shown in FIG. 11, vertex data 164A to 164D of a house 160 are included in the map information MP as neighborhood information. Then, the survey work range calculation unit 112C calculates a range where the interval between the

vertex data

154A and 154C of the house 150 and the

vertex data

164B and 164D of the house 160 is a predetermined distance or less as the non-survey target range 162. do.

In this way, the information receiving unit 112B of the terminal 100 acquires the peripheral shape information CO of the house 150 and at the same time acquires the map information MP around the house 150. Then, the investigation work range calculation unit 112C of the terminal 100 calculates, as the non-investigation target range 162, a range where the house 150 to be investigated and neighboring structures are adjacent to each other at a predetermined distance or less. Then, the calculated survey work range 152 and survey non-target range 162 are displayed on the display unit 120 of the terminal 100 by the display control unit 112E. As a result, the investigator can conduct the investigation while checking the investigation work range 152 and the non-investigation target range 162, and can avoid entering the non-investigation target range 162, so that the investigation can be conducted safely. can.

In addition, when recording the investigation work range 152 and the non-investigation target range 162 in the database 11 along with the investigation results, the reason why the investigation work area 152 and the non-investigation target range 162 were excluded as a trail (for example, it was excluded because it is close to a neighboring residence, etc.) be associated and recorded. This allows a third party to efficiently judge the sufficiency of the investigation results.

FIG. 12 is a diagram showing another example of the investigation work range calculated by the investigation work range calculation unit 112C. Note that the parts already described in FIG. 10 are designated by the same reference numerals, and the description thereof will be omitted.

In this example, calculation of the survey work range when the house 150 is adjacent to the river 170 will be explained. In this way, when the house 150 to be investigated is adjacent to a place that is topographically difficult to enter and investigate, the investigation work range calculation unit 112C also calculates the non-investigation target range 162.

The information receiving unit 112B of the terminal 100 receives the outer circumferential shape information CO and map information MP of the house 150 that is the object of investigation. The investigation work range calculation unit 112C calculates the investigation work range 152 and the non-investigation target range 162 based on the outer circumferential shape information CO and the map information MP. Here, the map information MP includes topographic information that is information about the topography in the vicinity of the house 150. In the case shown in FIG. 12, the position information of the river 170 is included in the map information MP as topographic information. Then, the survey work range calculation unit 112C calculates a range where the interval between the vertex data 154A and the vertex data 154C of the house 150 and the river 170 is a predetermined distance or less as the non-survey target range 162.

In this way, the information receiving unit 112B of the terminal 100 acquires the peripheral shape information CO of the house 150 and at the same time acquires the map information MP around the house 150. Then, the investigation work range calculation unit 112C of the terminal 100 calculates an area where the house 150 to be investigated is adjacent to a place where it is difficult to enter and conduct an investigation at a predetermined distance or less, as an area other than the investigation target area 162. Calculated as Then, the calculated survey work range 152 and survey non-target range 162 are displayed on the display unit 120 of the terminal 100 by the display control unit 112E. As a result, the investigator can conduct the investigation while checking the investigation work range 152 and the non-investigation target range 162, and can avoid entering the non-investigation target range 162, so that the investigation can be conducted safely. can.

Note that when displaying the survey excluded range 162, the reason why it is excluded as a trail (for example, it is excluded from the survey because it is adjacent to a river, etc.) may be associated and stored. This allows a third party to efficiently judge the sufficiency of the investigation results.

Next, the setting of the width L when calculating the investigation work range will be explained.

When calculating the survey work range, the survey work range calculation unit 112C calculates a predetermined width from the structure (line connecting adjacent vertices: corresponds to the outer wall of the house). Establish the scope of investigation work.

In the example described above (FIGS. 10, 11, and 12), the investigation work range 152 is calculated in a range separated by the width L from the house 150. The investigation work range calculation unit 112C can calculate investigation work ranges with various widths L.

FIG. 13 is a diagram illustrating the setting of the width L of the investigation work range.

Reference numeral 171 is a diagram illustrating the width that is set when calculating the survey work range for a one-story house whose structure is to be surveyed.

In the case of a one-story type house, the height of the house itself that is the subject of the survey is not very high. Therefore, the width L of the investigation work range can be set relatively narrow. For example, if the object of investigation is a one-story house, the width L of the investigation work range is set to 2.5 m to 3 m.

Reference numeral 172 is a diagram illustrating the width L that is set when calculating the survey work range when the structure to be surveyed is a high-story building (for example, a building).

In the case of a high-story building, the structure itself that is the object of the investigation is tall, so it is necessary to conduct the investigation from a position slightly distant from the structure. Therefore, it is necessary to set a wide range of scope of investigation work. For example, when the object of investigation is a high-story building, the width L of the investigation work range is set to 10 m.

Reference numeral 173 is a diagram illustrating the width that is set when calculating the survey work range for a rigid frame structure.

In the case of a rigid frame structure, there is no need to inspect the appearance of the first floor, but it is necessary to investigate the appearance of the second and higher floors. Therefore, it is necessary to set a wide scope of research work. For example, if the object of investigation is a rigid frame structure, the width of the investigation work range is set to 5 m.

As explained above, when calculating the survey work range, the survey work range calculation unit 112C can set the width L of the survey work range according to the height and structure of the structure to be surveyed. . Thereby, the investigation work range calculation unit 112C can calculate an investigation work range that allows more accurate investigation.

FIG. 14 is a diagram illustrating a case where the width L of the investigation work range is arbitrarily set by the investigator.

There are cases where the investigator sets the width of the investigation work range arbitrarily, such as when the investigator actually goes to the investigation site and sets the width L of the investigation work range after confirming the on-site situation.

FIG. 14 shows a user interface 182 displayed on the display unit 120 of the terminal 100. Note that the user interface 182 is displayed on the display unit 120 by the display control unit 112E by executing the application program.

The surveyor actually goes to the location of the house 178 and inputs the width L of the survey work range into the input area 176 for the width L of the survey work range on the user interface 182. The surveyor actually goes to the location of the house 178 and inputs the width L of the survey work range, and the survey work range calculation unit 112C calculates the survey work range 180 based on the input width L of the survey work range. be able to.

As explained above, when calculating the survey work range, the survey work range calculation unit 112C can set the width L of the survey work range based on input from the investigator. Thereby, the investigation work range calculation unit 112C can calculate the investigation work range in accordance with the actual investigation site.

<Identification of surveyed range>
Next, the identification of the researched range performed by the researched range identification unit 112D will be described.

The surveyed range specifying unit 112D of the terminal 100 identifies the surveyed range in the survey work range based on the location information of the terminal 100. A specific example of the surveyed range specified by the surveyed range specifying unit 112D will be described below. Note that the parts already described in FIG. 10 are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 15 is a diagram illustrating an example of identifying a surveyed range by the surveyed range specifying unit 112D.

In the case of this example, the surveyed range specifying unit 112D identifies the survey work range 152 in which the terminal 100 stayed for a predetermined time (second threshold) or more as the surveyed range 200. If the terminal 100 stays in the investigation work range 152 for a predetermined time or longer, it can be estimated that the investigator stayed in the investigation work range and conducted the investigation. Therefore, when the terminal 100 stays in the survey work range 152 for a predetermined time or more, the surveyed range identification unit 112D identifies the range as the surveyed range 200. Specifically, the surveyed range specifying unit 112D determines whether the terminal 100 is staying in the survey work range 152 based on the position information of the GPS receiver 122 of the position information output unit 140 of the terminal 100 and the time information output from the timer 130. Measure the time spent. Then, when the terminal 100 stays for a predetermined time or longer, the surveyed range specifying unit 112D identifies the survey work range 152 as the surveyed range 200. For example, when the terminal 100 stays in the survey work range 152 for one minute or more, the surveyed range specifying unit 112D identifies the survey work range as the surveyed range.

In this way, the surveyed range specifying unit 112D identifies the surveyed range 200 when the terminal 100 stays in the survey work range 152 for a predetermined period of time or more, so it is not possible to accurately identify the surveyed range. can.

FIG. 16 is a diagram showing another example of specifying the investigated range by the investigated range specifying unit 112D.

In the case of this example, the surveyed range identifying unit 112D identifies the survey work range 152 in which the terminal 100 has stayed a predetermined number of times (third threshold) or more as the surveyed range 200. If the terminal 100 stays in the investigation work range 152 a predetermined number of times or more, it can be estimated that the investigator stayed in the investigation work range 152 and conducted the investigation. Therefore, when the terminal 100 stays in the survey work range 152 a predetermined number of times or more, the surveyed range identification unit 112D identifies the range as the surveyed range 200. Specifically, the surveyed range specifying unit 112D determines whether the terminal 100 stays in the survey work range 152 based on the position information of the GPS receiver 122 of the position information output unit 140 of the terminal 100 and the number of times information output from the counter 132. Measure the number of times. Then, when the terminal 100 has stayed a predetermined number of times or more, the surveyed range identifying unit 112D identifies the survey work range as the surveyed range. For example, if the terminal 100 has stayed in the research work range three or more times, the researched range identification unit 112D identifies the research work range as the researched range.

In this way, the surveyed range specifying unit 112D identifies the surveyed range 200 when the terminal 100 has stayed in the survey work range 152 a predetermined number of times or more, so it is not possible to accurately identify the surveyed range. can.

FIG. 17 is a diagram showing another example of specifying the investigated range by the investigated range specifying unit 112D.

In the case of this example, when the terminal 100 faces the wall of the house 150 to be investigated for a predetermined period of time or more, the surveyed range specifying unit 112D investigates the survey work range corresponding to the wall. specified as the completed range 200 (see reference numeral 182).

The surveyed range specifying unit 112D obtains the orientation vector (direction information) V of the terminal 100 using the acceleration sensor 126 and the gyro sensor 128 in the position information output unit 140 of the terminal 100. Since the investigator carries the terminal 100 with him during the investigation, it can be estimated that the orientation vector V of the terminal 100 and the orientation of the investigator INS are equal, and the orientation vector of the terminal 100 (direction information) If V faces the wall of the house 150 for a predetermined period of time or more, the survey work range 152 corresponding to the wall is set as the surveyed range 200. Specifically, as indicated by reference numeral 184, if the direction vector V of the terminal 100 continues to intersect with the side of the wall of the house 150 for a predetermined period of time or more, the surveyed range specifying unit 112D determines whether Identify the surveyed area.

In this way, the surveyed range specifying unit 112D identifies the surveyed range when the terminal 100 faces the wall of the house 150 for a predetermined period of time or more, so it is possible to accurately identify the surveyed range 200. It can be carried out.

FIG. 18 is a diagram showing another example of specifying the investigated range by the investigated range specifying unit 112D. Note that the illustrated camera 134 is provided on the front or back surface of the terminal 100.

In the case of this example, when the camera 134 is directed toward the wall of the house 150 and a photograph is taken, the surveyed range specifying unit 112D converts the survey work range 152 corresponding to the wall into the surveyed range 200. Specify as. If the wall of the house 150 is photographed by the camera 134, it can be presumed that an investigator is conducting an investigation. Therefore, the surveyed range identification unit 112D uses information output from the GPS receiver 122, acceleration sensor 126, and gyro sensor 128 of the location information output unit 140 of the terminal 100 to direct the camera of the terminal 100 toward the wall of the house 150. When a photograph is taken with the camera facing the wall 134, the survey work range 152 corresponding to the wall is specified as the surveyed range 200.

In this way, when the wall of the house 150 to be investigated is photographed by the camera 134 of the terminal 100, the surveyed range identification unit 112D determines the survey work range 152 corresponding to the wall as the surveyed range 200. Therefore, the surveyed range 200 can be accurately specified.

FIGS. 19 and 20 are diagrams showing other examples of specifying the investigated range by the investigated range specifying unit 112D.

In the case of this example, the surveyed range specifying unit 112D determines that for the survey work range that has been calculated redundantly based on a plurality of different wall surfaces of the house 150a that is the survey target, all the walls from which the survey work range is calculated are It is presumed that the investigation has been carried out, and the scope of the investigation is determined.

In the case shown in FIG. 19, the investigation work range calculation unit 112C calculates the investigation work range 152 for the house 150a. The investigation work range calculation unit 112C calculates an overlapping investigation work range 152a due to walls 206 and walls 208 of the house 150a.

FIG. 20 is a diagram illustrating the identification of the surveyed range of the duplicate survey work range 152a. In addition, in the case described below, the surveyed range specifying unit 112D, as explained with reference to FIG. , identify the surveyed range.

In the case indicated by reference numeral 210, the orientation vector V of the terminal 100 points toward the wall 206 for a predetermined period of time or more. Therefore, the surveyed range specifying unit 112D specifies that the survey of the wall 206 has been completed in the duplicate survey work range 152a. However, the surveyed range specifying unit 112D has not yet completed the survey of the wall 208 in the redundant survey work range 152a, so it has not yet specified the redundant survey work range 152a as a surveyed range.

In the case indicated by reference numeral 212, the orientation vector V of the terminal 100 points toward the wall 208 for a predetermined period of time or more. Therefore, the surveyed range specifying unit 112D determines that the survey of the wall 208 has been completed in the duplicate survey work range 152a.

In the case indicated by reference numeral 214, the surveyed range identifying unit 112D determines that the wall 206 and the wall 208 have been surveyed, and therefore identifies the duplicate survey work range 152a as the surveyed range 200a.

In this way, regarding the duplicate investigation work range 152a, when the investigation is completed for all of the investigation targets for which the duplicate investigation work range 152a has been calculated, the investigated range specifying unit 112D converts the overlap investigation work range 152a into the investigated range. 200a. Thereby, the surveyed range specifying unit 112D can accurately specify the surveyed range 200a.

FIG. 21 is a diagram showing another example of specifying the investigated range by the investigated range specifying unit 112D.

In this example, if the degree of damage to the house to be investigated is determined to be "completely destroyed" before the surveyor has investigated the entire survey work range, the surveyed range specifying unit 112D to be identified as not subject to investigation.

In the case indicated by reference numeral 216, the house 150 is investigated, and when the survey of the surveyed area 200 is completed, the investigator determines the degree of damage to the house 150 as "total destruction." Here, "completely destroyed" indicates the degree of damage that has been sustained the most in the damage recognition investigation, and is a case where no further investigation of the house 150 is necessary.

As shown by reference numeral 218, when the investigator inputs the investigation result as "completely destroyed" into the terminal 100, the investigation completed area identification unit 112D determines that the remaining investigation work area 152 that has not yet been investigated is an investigation target that is not subject to investigation. It is specified as the outer range 220.

In this way, if the extent of damage is determined to be "total destruction" even during the investigation, the investigated range specifying unit 112D identifies the remaining investigation work range as the non-investigated range 220. Thereby, the investigator does not have to continue the investigation after the damage has been determined, and can conduct a more efficient investigation. Note that when recording the investigation results in the server device 10, it is associated with the location that is outside the investigation target range 220, and records that the location has been determined to be completely destroyed and is therefore excluded from the investigation target. This allows a third party to efficiently judge the sufficiency of the investigation results.

Furthermore, in the example described above, an example was explained in which the result of the damage determination investigation was a complete destruction, but the application of the present invention is not limited to this. For example, if a survey result that does not require the continuation of a subsequent survey is input (a survey result that is equal to or higher than the first threshold), the scope of the survey work that has not yet been surveyed is treated as a non-survey scope as explained above. May be specified.

<Dividing the scope of investigation work>
Next, the division of the survey work scope will be explained. As described above, the survey work range is set to surround the outer periphery of the house to be surveyed. Then, the investigator sequentially conducts the investigation along the investigation work range displayed on the display unit 120 of the terminal 100, and the investigated range identification unit 112D identifies the researched range within the investigation work range. In this case, the surveyed range identifying unit 112D can accurately identify the surveyed range because the survey work range is divided into predetermined sizes. Therefore, it is preferable that the investigation work range calculation unit 112C divides the calculated investigation work range. For example, the survey work range calculation unit 112C divides the survey work range into squares with sides of 2.5 m or cubes with sides of 2.5 m. In addition, in order to accurately understand the surveyed area, it is better to have smaller sides of squares and cubes, but considering the error and processing performance of the GPS function, one side should be within an area of several meters (for example, 2.5 m). It is preferable to separate the

FIG. 22 is a diagram illustrating a two-dimensional survey work range 152 into which the house 150 is divided. Note that this investigation work range 152 is also displayed on the display unit 120 of the terminal 100.

In the case shown in FIG. 22, the investigation work range 152 is divided into squares with T on each side. When calculating the survey work range 152, the survey work range calculation unit 112C divides the survey work range 152 into squares of a preset size (one side=T). Note that the terminal 100 stores and manages, on the computer-readable medium 116, the latitude and longitude coordinates of each vertex forming a square into which the survey work range 152 is divided.

The surveyed range specifying unit 112D identifies the surveyed range for each divided square. The divided investigation work range U1 is an uninvestigated research work range 152, and is, for example, a range in which there is no stay history of the terminal 100. Furthermore, the divided investigation work range U2 is the research work range 152 in which the investigation has progressed to an intermediate stage, and is, for example, a range in which there is a stay history (staying time) of the terminal 100 but is less than a threshold value (second threshold value). . Furthermore, the divided investigation work range U3 is a researched range in which the research has been completed, and is, for example, a range in which the stay history of the terminal 100 is equal to or greater than a threshold value (second threshold value). Note that the investigation work ranges U1 to U3 are displayed on the display unit 120 in different colors and display formats. For example, the investigation work ranges U1 to U3 are displayed in different colors such as red, light red, and white in the order of investigation work range U1, investigation work range U2, and investigation work range U3. In this way, by dividing the survey work range 152 into squares and identifying the surveyed range for each divided square, the surveyor can conduct the survey with higher accuracy. Further, as shown in FIG. 22, by changing the display mode in stages according to the degree of completion of the investigation, the investigator can easily check the degree of progress of the investigation.

FIG. 23 is a diagram illustrating a three-dimensional survey work range 152 into which the house 150 is divided. Note that this investigation work range 152 is also displayed on the display unit 120 of the terminal 100.

In the case shown in FIG. 23, the investigation work range 152 is divided into cubes with one side of T. When calculating the survey work range 152, the survey work range calculation unit 112C divides the survey work range 152 into cubes of a preset size (one side=T). A division ID is attached to each cube that divides the investigation work range 152. In the case shown in FIG. 23, division IDs "123456789_123456789A" to "123456789_123456789C" are shown as an example. Note that the terminal 100 stores and manages, on the computer-readable medium 116, the latitude and longitude coordinates of each vertex forming a cube into which the survey work range 152 is divided.

When the survey work range is calculated in three dimensions, the surveyed range specifying unit 112D obtains the current position and altitude of the terminal 100 from the GPS receiver 122 and the atmospheric pressure sensor 124, for example. Then, the surveyed range specifying unit 112D searches whether the current position and altitude of the terminal 100 are included in any cube of the survey work range 152 divided into cubes. If a cube containing the location and altitude of the terminal 100 is detected, the surveyed range specifying unit 112D stores the investigator's identifier, the time of entry into the cube, the number of times of entry into the cube, as information associated with the cube. Record the total time spent in the cube. For example, in the case shown in FIG. 24, information that identifies the investigator (1st team InspectorRay), total stay time (inspector-TotalStayTime), inspector entry time stamp (inspector-EnterTimestamp), investigator current stay time (inspector-CurrentStayTime) ) are stored in association with the division ID. Then, the surveyed range identification unit 112D determines the orientation of the surveyor in the horizontal plane based on the information output from the acceleration sensor 126 and the gyro sensor 128, in order to determine whether the stay inside the cube is due to survey work. (The direction of the compass) may be calculated and counted as the number of times and stay time only when facing the wall.

Furthermore, if the investigator finds damage to the wall of the house 150 that is the subject of investigation, the investigator may photograph the wall of the house 150 that is the subject of investigation using the camera 134 of the terminal 100. In this case, the surveyed range specifying unit 112D photographs the damage when the photographing direction of the camera 134, which is calculated from the information output from the acceleration sensor 126 and the gyro sensor 128, is facing any wall of the house 150. It is determined that the Then, a cube is searched based on the position and altitude of the terminal 100 at the time of photographing, and the photographing time and photographed image are associated with the searched cube as information indicating that the photographing action has occurred, and the data is stored in the computer-readable medium 116. Remember.

In this way, when the survey work range is shown in three dimensions, the survey work range 152 is divided into cubes and displayed, and the surveyed range identification unit 112D indicates the survey work range 152 divided into cubes. Identify the range of

<Examples of other surveys>
In the example described above, an example of damage identification investigation based on the appearance of a house was explained. However, the application of the present invention is not limited to damage assessment investigation on the exterior of a house. For example, it can be applied to the case of conducting a damage determination investigation inside a house.

FIG. 25 is a diagram showing the investigation work range inside the house 150. Note that the illustrated investigation work range is displayed on the display unit 120 of the terminal 100.

When conducting a damage determination investigation inside the house 150, the investigator conducts the investigation along the investigation work scope 153. This allows the investigator to comprehensively investigate the scope of the investigation work.

<Example of information processing device>
In the above example, the damage investigation system 1 was explained. However, the invention can be practiced with other embodiments. For example, the present invention can also be implemented by the information processing device 102 (terminal) that includes the database 11.

FIG. 26 is a diagram showing an example of the hardware configuration of the information processing device 102 including the database 11. Note that the same reference numerals are given to the parts already described in FIG. 6, and the description thereof will be omitted.

When conducting an investigation, the investigator carries the information processing device 102 with him. The information processing device 102 displays the survey work range and the surveyed range on the display unit 120, and the investigator can conduct the survey while checking the survey work range and the survey completed range displayed on the display unit 120.

The information processing device 102 includes a second processor 112, a computer readable medium 116, a communication interface 114, a camera 134, a display section 120, a position information output section 140, and a database 11. Note that the database 11 stores outer circumferential shape information CO and map information MP.

The information processing device 102 receives a request to read outer circumferential shape information CO associated with the house ID of the house to be investigated, based on input from the investigator. Thereafter, the information processing device 102 reads the outer circumferential shape information CO related to the house ID from the internal database 11 based on the read request. Thereafter, an investigation work range is calculated based on the read outer circumferential shape information CO. Thereby, the information processing device 102 can acquire the outer circumferential shape information CO and calculate the investigation work range even in a situation where communication via the network NW is impossible.

As explained above, in the information processing device 102 described above, the investigation work range is calculated based on the outer circumferential shape information CO of the house to be investigated, and the calculated investigation work range is displayed. Further, based on the position information of the information processing device 102, a surveyed range within the survey work range in which the survey has been performed is specified. Thereby, by using the information processing device 102, the investigator can suppress failure to detect damage to the structure that is the object of investigation, and can conduct the investigation efficiently.
