  Hereinafter, a position information calculation device, a position information calculation method, and a position information calculation program according to an embodiment of the present invention will be described in detail with reference to the drawings. In each figure shown below, the same numerals are given about the same composition.

  First, an outline of a position information calculation system including a position information calculation apparatus according to an embodiment will be described with reference to FIG.

  In FIG. 1, a position information calculation system 1 is a system for calculating position information of a specific part of a structure. The position information calculation system 1 shows a case where the position information of a specific part of a solar panel 50 exemplified as a structure that specifies a failure part is calculated. The position information calculation system 1 includes a position information calculation device 10, a terminal 20, a failure information report device 30, and a photographing device 40.

  The imaging device 40 includes a camera 41 and a position information detection device 42. The imaging device 40 is, for example, a drone (unmanned aircraft). The imaging device 40 moves above the solar panel 50 and investigates a failure of the solar panel 50. The imaging device 40 is assumed to be able to move freely above the solar panel 50 by, for example, remote operation or autonomously moving on a predetermined movement route. The imaging device 40 is not limited to a drone, and may be a crane, for example.

  The camera 41 is attached to the photographing device 40 and photographs the solar panel 50. The camera 41 has an imaging device that captures still images or moving images. The camera 41 may perform, for example, photographing with visible light, photographing with infrared light, photographing with ultraviolet light, and the like. For example, when an abnormality occurs in the solar panel, the temperature of the abnormal part may be higher than that of the surrounding normal part.

  The position information detection device 42 detects position information of the imaging device 40. The position information is information such as latitude, longitude, altitude and direction. Information on latitude, longitude, and altitude can be detected by receiving a signal transmitted from a GPS (Global Positioning System) satellite, for example. The altitude information may be detected by detecting the atmospheric pressure.

  The direction is a shooting direction of the camera 41. In the present embodiment, it is assumed that the center of the image captured by the camera 41 coincides with the direction detected by the position information detection device 42. The direction includes an azimuth angle (azimuth angle) and an elevation angle. The azimuth angle is a rotation angle from the reference direction in the horizontal direction. The reference direction is, for example, magnetism or true north. The azimuth angle can be detected by a compass that detects geomagnetism. The elevation angle is an angle in the vertical direction from the horizontal direction. In the present embodiment, the camera 41 captures the solar panel 50 downward from above, and therefore uses a depression angle. By detecting the azimuth angle and the depression angle, the shooting direction of the camera 41 can be detected. In the present embodiment, the case where the depression angle is detected on the assumption that the photographing apparatus 40 is a drone or the like will be described. However, for example, when the horizontal direction is maintained at the time of photographing by a leveler or the like, the depression angle is always 90. Because it is °, there is no need for detection.

  The image capturing device 40 transmits the captured image captured by the camera 41 and the position information detected by the position information detecting device 42 to the failure information reporting device 30 wirelessly or by wire. For example, the imaging device 40 may transmit a captured image and position information in response to a shooting instruction from the failure information reporting device 30. The captured image and the position information are always associated with each other. The position information may be recorded as accompanying information according to the file format of the captured image, for example.

  The failure information reporting device 30 transmits failure information of the solar panel 50 including the captured image acquired from the imaging device 40 and the location information to the location information calculation device 10. The failure information reporting device 30 may transmit information other than the captured image and the location information to the location information calculation device 10 as the failure information. For example, the failure information reporting device 30 may add and transmit a free comment regarding a failure of the solar panel 50 or a selectable comment. The comment about the failure is, for example, a column number or a module number indicating the failure position of the solar panel, a failure degree, an urgent repair, and the like. For example, the failure information reporting device 30 may transmit information such as the power generation status of the solar panel 50, the operator name of the failure investigation, and the date and time.

  The position information calculation device 10 calculates the position information of the failure location of the solar panel 50 based on the captured image and the position information acquired from the failure information report device 30. Details of the method of calculating the failure location will be described later with reference to FIG. The position information calculation device 10 creates a report regarding the failure of the solar panel 50 and provides the report to the terminal 20 or the like. The report may include a captured image of the failure location captured by the camera 41 and access information for acquiring the calculated location information of the failure location. The position information calculation apparatus 10 generates a Web screen that can be browsed from a browser, for example, by superimposing information indicating a failure location on map data. The location information calculation device 10 authenticates whether or not the user has access authority to the access request from the terminal 20, and if the authentication is OK, provides the generated Web screen so that the terminal 20 can view it. The position information calculation apparatus 10 may acquire, for example, a repair result of a failure location from the terminal 20.

  The terminal 20 acquires the location information of the failure location based on the Web screen generated by the location information calculation device 10. The terminal 20 displays the current position of the terminal 20 on the Web screen based on the signal from the GPS satellite. The terminal 20 can easily identify the failure location of the solar panel 50 based on the location information of the failure location and the current location. The terminal 20 may record a repair record of the solar panel 50 in the position information calculation device 10.

  In FIG. 1, the position information calculation system 1 shows a case where the position information calculation apparatus 10, the terminal 20, the failure information report apparatus 30, and the photographing apparatus 40 are each provided. However, the configuration of the position information calculation system 1 is not limited to this. That is, the location information calculation system 1 may include two or more location information calculation devices 10, terminals 20, failure information reporting devices 30, or imaging devices 40. For example, failure investigation may be performed by the imaging device 40 in each of a plurality of solar power plants. Further, a plurality of workers may each have the terminal 20 and acquire the location information of the failure location.

  Moreover, although the case where the imaging device 40 has one camera was shown, the imaging device 40 may have, for example, two cameras (stereo cameras). Further, the position information calculation device 10 may acquire captured images captured from different directions by the plurality of imaging devices 40.

  In addition to calculating the position information of the solar panel, the position information calculation system 1 may calculate position information of, for example, a road, a track, a bridge, a building, and a dam.

  Next, imaging data acquired by the position information calculation apparatus 10 according to the embodiment will be described with reference to FIG. FIG. 2 shows a shooting situation of shooting data shot by the shooting device 40 and acquired by the position information calculation device 10.

  FIG. 2A is a top view of the imaging device 40. The photographing apparatus 40 includes four propellers 43 and a main body 44 that couples the propellers 43 to each other. A position information detection device 42 is provided on the upper portion of the main body 44. In addition, a camera 41 is provided on the lower surface (not shown).

  The position information detection device 42 receives radio waves from GPS satellites, and detects latitude, longitude, and height information (x, y, h). The height h information is a value obtained by subtracting the altitude of the point where the solar panel 50 is installed from the altitude information obtained from the GPS.

<Azimuth angle AZ>
A direction n1 illustrated in FIG. 2A indicates an apparent upward direction of a captured image captured by the camera 41. A direction n0 indicates true north. An angle formed by the direction n0 and the direction n1 is an azimuth angle AZ. When the azimuth angle AZ is 0 °, the upward direction of the captured image is true north. On the other hand, when the azimuth angle AZ is 180 °, the downward direction of the captured image is true north. The azimuth angle AZ is detected as 0 ° to 360 ° or −180 ° to + 180 °.

<Depression AL>
The direction m1 illustrated in FIG. 2B indicates the direction of the center position of the image captured by the camera 41. The direction m0 indicates the horizontal direction. The angle formed by the direction m0 and the direction m1 is the depression angle AL. When the depression angle AL is 90 °, the center of the captured image is directly below. On the other hand, when the depression angle AL is 0 °, the center of the captured image is in the horizontal direction. The depression angle AL is detected as 0 ° to 90 °. In addition, when the imaging device 40 is always kept horizontal, it is not necessary to detect the depression angle.

<Distance d>
The distance d from the camera 41 to the failure location TG can be calculated as d = h / cos (AL) based on the height h and the depression angle AL detected by the position information detection device 42. The height h is a numerical value obtained by subtracting the altitude of the solar panel from the photographing altitude detected from the GPS.

<Ratio r>
When the viewing angle of the camera 41 is fixed, the two-dimensional distance of the captured image changes according to the distance from the camera to the target location. For example, it is assumed that the length on the captured image of one side of the solar panel in the substantially horizontal direction is a0 [cm] at d0 [m] whose distance is known in advance. Assuming that the length is a1 on the captured image when the distance at the time of shooting is d1, the ratio r is a constant value according to the following equation.
Ratio r = a1 / a0 = d1 / d0

  That is, if the photographing altitude at the time of photographing is known, the height h and the distance d are known, and the ratio r is fixed, so that the actual distance can be calculated from the two-dimensional distance on the photographed image.

  Next, failure information acquired by the position information calculation apparatus 10 according to the embodiment will be described with reference to FIG. The failure information is information relating to a failure of the solar panel 50 provided from the failure information reporting device 30 to the position information calculating device 10.

  In FIG. 3, the failure information includes “shooting latitude”, “shooting longitude”, “shooting altitude”, “AZ”, “AL”, “failure information”, and “failure photo data”. “Shooting latitude”, “Shooting longitude”, “Shooting altitude”, “AZ”, and “AL” are data detected by the position information detection device 42. “Failure information” is a comment input by an operator who conducted a failure investigation of the solar panel 50. “Failure photograph data” is binary data of a photographed image photographed by the camera 41.

  FIG. 3 shows the case where one piece of failure information is provided. For example, a plurality of pieces of failure information may be provided together. For example, when failure information is provided regularly, failures that occur within a predetermined period are collectively provided.

  Next, the hardware configuration of the position information calculation apparatus 10 according to the embodiment will be described with reference to FIG.

  In FIG. 4, the position information calculation device 10 includes a CPU 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, an HDD 14, an operation unit 15, a display unit 16, and a communication I / F 17.

  The position information calculation device 10 can be a general-purpose computer such as a desktop PC or a server device. The position information calculation device 10 may be a control device dedicated to position information calculation or an industrial control device such as a PLC (Programmable Logic Controller). The position information calculation device 10 can execute a position information calculation program described later.

  The CPU 11 controls the position information calculation device 10 by executing a position information calculation program stored in the RAM 12, ROM 13, or HDD 14. The position information calculation program is acquired from, for example, a recording medium in which the position information calculation program is recorded or a server that provides the program via a network, installed in the HDD 14, and stored in the RAM 12 so as to be readable from the CPU 11.

  The operation unit 15 is, for example, a keyboard, a mouse, or a switch that enables an operation input by the operator of the position information calculation apparatus 10. The display unit 16 is, for example, a liquid crystal display or a lamp having a display function for displaying information to an operator. Note that the operation unit 15 and the display unit 16 may be, for example, a touch panel having an operation display function.

  The communication I / F 17 controls communication with other devices via wireless LAN communication, wired LAN communication, infrared communication, short-range wireless communication, and the like. The communication I / F 17 controls communication with the terminal 20, the failure information reporting device 30, or the cloud server 90 via the network 9. Here, the cloud server 90 may hold, for example, a part of data held by the position information calculation device 10 or execute a part of the function of the position information calculation device 10.

  Next, the functional configuration of the position information calculation apparatus according to the embodiment will be described with reference to FIG.

  In FIG. 5, a position information calculation device 10 includes a map data holding unit 101, an information acquisition unit 102, a position information calculation unit 103, a position information holding unit 104, an access information generation unit 105, a map data management unit 106, and a structure data management. Unit 107, report generation unit 108, authentication data holding unit 109, access authentication unit 110, information providing unit 111, and communication unit 114. The information providing unit 111 includes a position information superimposing unit 112 and a display screen generating unit 113.

  Each function of the position information calculation device 10 is a functional module realized by a position information calculation program (software) that controls the position information calculation device 10. The position information calculation program is executed by the CPU 101.

  The map data holding unit 101 holds map data including position information of the solar panel 50 as a structure. The map data is, for example, a topographic map, an aerial photograph, a structure drawing, or the like. The topographic map, the aerial photograph, and the drawing of the structure may be superimposed to form one map data. The map data includes position information of latitude information and longitude information. The position information of the map data may include altitude information. The map data is a map expressed in 2D or 3D. The map data includes the arrangement or shape of the structure. For example, the map data includes the panel arrangement of the solar panels 50 and the position information of each panel. The map data can be enlarged or reduced in size by changing the scale. It should be noted that a structure having a size in the height direction, such as a wall surface of a building or a bridge, has position information in the height direction. The aerial photograph used for the map data is taken with, for example, visible light or infrared light. The aerial photograph may be taken with ultraviolet light. The map data management unit 106 may add, update, or delete the map data so that the latest state is attached. The drawing data may be vector data rasterized.

  The information acquisition unit 102 acquires shooting data including shooting image data and shooting position information of the shooting equipment when a specific part of the structure is shot with the shooting equipment. In the present embodiment, the information acquisition unit 102 acquires shooting data including data of a captured image and position information of the camera 41 when the camera 41 captures a failure portion of the solar panel 50. For example, the information acquisition unit 102 receives a transmission request from the failure information reporting device 30 and receives transmission data from the failure information reporting device 30. Further, the information acquisition unit 102 may acquire shooting information by receiving a mail from a mail server (not shown). Further, the information acquisition unit 102 may inquire the failure information reporting device 30 about the presence or absence of failure information, and may acquire the failure information. The information acquisition unit 102 provides the acquired shooting data to the position information calculation unit 103.

  The position information calculation unit 103 calculates the position information of a specific location based on the map data held in the map data holding unit 101 and the shooting data acquired in the information acquisition unit 102. First, the position information calculation unit 103 calculates the distance (shooting distance) from the shooting position of the shot image taken by the camera 41 to the failure location. The position information calculation unit 103 calculates the actual distance from the actual location of the center point of the captured image to the failure location based on the calculated distance from the capture location to the failure location and the distance between the center point and the specific location in the captured image. Can be calculated. If the distance and the azimuth angle are known, the position information of the failure location can be calculated.

  In the present embodiment, the position information calculation unit 103 has shown the case where the position of the failure location is calculated from the shooting distance. However, for example, by performing pattern matching between the shot image and the map information, the center of the shot image is obtained. The actual distance from the point location to the failure location can be calculated. Thereby, for example, even when the camera 41 makes the focal length variable, it is possible to calculate the position information of the failure location.

  In camera lenses, image distortion tends to occur in the lens periphery, so the distance between the center and the fault location in the captured image is measured as close to the center point as possible. It is better to do so. The position information calculation unit 103 holds the calculated position information in the position information holding unit 104.

  The position information holding unit 104 holds position information so that it can be acquired from the terminal 20. The position information holding unit 104 can be realized by, for example, the HDD 14.

  The access information generation unit 105 generates access information for accessing the location information of the fault location held in the location information holding unit 104. The access information is, for example, a two-dimensional code that represents the address of the position information holding unit 104. The access information may be a predetermined code provided to the contactless card. The access information may be a predetermined ID for accessing the position information holding unit 104. For example, the access information generation unit 105 may generate access information whose use time is limited. Further, the access information generation unit 105 may generate access information that restricts the number of accesses and the terminals to be accessed.

  The map data management unit 106 adds, deletes, or updates map data. For example, the map data management unit 106 acquires the latest map data from the cloud server 90 that provides the map data, and updates the map data. Map data using general aerial photographs may be updated once every few years, for example. The map data management unit 106 can update the map data to the latest state by acquiring limited photographs and drawings of the structure.

  The structure data management unit 107 manages information related to the structure. For example, the structure data management unit 107 manages information such as failure history, repair history, service life, periodic inspection information, and model of the solar panel 50. The structure data management unit 107 updates the repair history by receiving the repair report from the terminal 20. The structure data management unit 107 may output managed information.

  The report generation unit 108 generates a report. The report generation unit 108 creates a report regarding the failure of the solar panel 50 and provides it to the terminal 20 or the like. The report may include a captured image of the failure location captured by the camera 41 and access information for acquiring the calculated location information of the failure location. The report generation unit 108 may generate the report as print data, data that can be displayed on the Web screen, or a predetermined file format. The report generation unit 108 may provide the generated report to the terminal 20. The report can include the access information generated by the access information generation unit 105.

  The authentication data holding unit 109 holds authentication data used by the access authentication unit. The authentication data holds authentication data including an access ID and a password, for example. The authentication data holding unit 109 may hold authentication data for performing biometric authentication.

  The access authentication unit 110 authenticates an access request based on the access information generated by the access information generation unit 105. For example, the access authentication unit 110 requests input of authentication information to the terminal 20 that has made a bad request. The access authentication unit 110 compares the input access information with the authentication data held in the authentication data holding unit 109 to authenticate access. For example, the access authentication unit 110 may authenticate access based on a password whose use time is limited.

  In response to an access request based on the access information generated by the access information generating unit 105, the information providing unit 111 provides the position information of a specific location held in the position information holding unit 104.

  Further, the information providing unit 111 changes the location information of the specific location to be provided in response to the access request authenticated by the access authentication unit 110. For example, the information providing unit 111 may provide different information for each user. For example, when the user is an administrator of the solar panel 50, the information providing unit 111 provides all information. On the other hand, when the user is a repair worker of the solar panel 50, the information providing unit 111 may provide only information necessary for repair.

  The information providing unit 111 also provides information on a display screen that can display the position information of the structure and the current position of the external device. For example, the information providing unit 111 provides a display screen as an application for the terminal 20 to display the current position. The application uses the GPS function (position information acquisition unit) of the terminal 20 to display the failure location of the solar panel 50 and the current location of the terminal 20 to facilitate reaching the failure location.

  In addition, the position information superimposing unit 112 of the information providing unit 111 provides position information superimposed on the map data at the failure location of the solar panel. The position information may be displayed with a predetermined icon on the map data.

  Further, the display screen generation unit 113 of the information providing unit 111 generates a display screen to be displayed on the terminal 20. For example, the display screen generation unit 113 generates a Web screen that can be displayed by the browser of the terminal 20. The information providing unit 111 can provide image data captured with at least one of visible light and infrared light as map data to be displayed. Further, the information providing unit 111 may provide the drawing data of the structure as map data.

  Note that the position information superimposed in the position information superimposing unit 112 may be displayed as image data in which the position information is shown in the map data. Further, the superimposed position information may be information that can be superimposed on the map data on the terminal 20 side. When the position information is superimposed on the map data on the terminal 20 side, the terminal 20 may select another map data instead of the map data provided from the information providing unit 111 and display the position information of the fault location. it can. Another map data can be used by, for example, a web service provided by the cloud server 90.

  The communication unit 114 controls communication with the terminal 20 and the like via the network 9. The communication unit 114 may control encrypted communication such as SSL (Secure Socket Layer), for example.

  In FIG. 5, the position information calculation device 10 includes a map data holding unit 101, an information acquisition unit 102, a position information calculation unit 103, a position information holding unit 104, an access information generation unit 105, a map data management unit 106, The functions of the structure data management unit 107, the report generation unit 108, the authentication data holding unit 109, the access authentication unit 110, the information provision unit 111, the position information superimposition unit 112, the display screen generation unit 113, and the communication unit 114 are realized by software. Explained the case. However, the one or more functions of the position information calculation device 10 may be realized by hardware.

  In addition, each of the functions of the position information calculation apparatus 10 may be implemented by dividing one function into a plurality of functions. In addition, each of the functions of the position information calculation apparatus 10 may be implemented by integrating two or more functions into one function.

  Further, the position information calculation device 10 may be a device realized by a single housing or a system realized by a plurality of devices connected via a network or the like. For example, the position information calculation device 10 may be a server device, a notebook PC, a tablet PC, a PDA, a smartphone, or a virtual device such as a cloud service provided by a cloud computing system. There may be.

  Moreover, you may make it implement | achieve one or more functions of each said function of the position information calculation apparatus 10 in another apparatus. That is, the position information calculation apparatus 10 does not have to have all the functions described above, and may have a part of the functions.

  Next, the functional configuration of the terminal 20 that communicates with the position information calculation device 10 of the embodiment will be described using FIG.

  The terminal 20 is a device such as a notebook PC, a tablet PC, a PDA, or a smartphone, for example, and can display the location information of the failure location acquired from the location information calculation device 10.

  The terminal 20 has functions of a communication unit 201, a display unit 202, a position information acquisition unit 203, and a position information processing unit 204.

  The communication unit 201 controls communication with the position information calculation device 10. The display unit 202 displays a display screen such as a Web screen provided from the position information calculation device 10. The position information acquisition unit 203 acquires the position information of the own device based on the radio wave of the GPS satellite. The position information processing unit 204 displays the position information of the own device acquired by the position information acquisition unit 203 on the display screen acquired from the position information calculation device 10 and including the position information of the solar panel 50. The position information processing unit 204 may navigate a route to a fault location using the position information of the own device.

The display screen generation unit 113 generates a portion of map data that is optimal for reaching the failure location as a display screen. The center position can be, for example, the position of the failure location. The terminal 20 can display the position of the failure location based on the image file and the position information.

  Next, a report provided by the position information calculation apparatus according to the embodiment will be described with reference to FIG.

  FIG. 9A is a report regarding a failure of the solar panel 50 created by the report generator 108. For example, the report generation unit 108 creates a report as print data or display data. The report generation unit 108 can include the two-dimensional code generated by the access information generation unit 105 in the upper right part of the report. The two-dimensional code is information for accessing the position information of the failure location of the solar panel described in this report.

  In FIG. 9B, the terminal 20 reads the two-dimensional code of the report. The two-dimensional code includes a URL (Uniform Resource Locator) for accessing the location information of the failure location.

  In FIG. 9C, the terminal 20 accesses the URL link destination and displays a Web screen. On the Web screen, a map showing the arrangement of the solar panels and a failure location of the solar panel indicated by a circle are displayed.

  In FIG. 9D, the terminal 20 displays the position of its own device on the screen based on the radio wave received from the GPS. Thereby, the operator who has the terminal 20 can grasp | ascertain the path | route to a failure location easily.

  Next, a report providing operation of the position information calculation apparatus 10 according to the embodiment will be described with reference to FIG. Note that the details of the operation in each step have already been described, and thus the description thereof is omitted.

  The position information calculation device 10 determines whether failure information has been acquired (step S11). The failure information can be received from the failure information reporting device 30. If it is determined that failure information has not been acquired (step S11: NO), the position information calculation device 10 repeats the process of step S11 and waits for acquisition of failure information.

  On the other hand, when it is determined that the failure information has been acquired (step S11: YES), the position information calculation device 10 records the failure information (step S12). The failure information can be recorded, for example, on the HDD 14 or the like.

  After executing the process of step S12, the position information calculation apparatus 10 calculates the height (step S13). The height can be calculated by subtracting the altitude of the solar panel from the shooting altitude.

  After executing the process of step S13, the position information calculation apparatus 10 calculates the shooting distance (step S14). The shooting distance can be calculated from the height and the depression angle.

  After executing the process of step S14, the position information calculation apparatus 10 calculates the in-image distance (step S15). The in-image distance can be calculated based on the distance between the center position and the failure location in the captured image.

  After executing the process of step S15, the position information calculation device 10 calculates position information (step S16). The position information can be calculated based on the azimuth angle and the actual distance.

  After executing the process of step S16, the position information calculation apparatus 10 holds the position information (step S17). The position information can be held in the position information holding unit 104, for example.

  After executing the process of step S17, the position information calculation device 10 superimposes the position information on the map data (step S18). After executing the process of step S18, the position information calculation apparatus 10 generates a Web page (step S19). After executing the process of step S19, the position information calculation apparatus 10 generates access information (step S20). After executing the process of step S20, the position information calculation apparatus 10 generates a report (step S21). After executing the process of step S21, the position information calculation apparatus 10 provides the generated report (step S22). After executing the process of step S22, the position information calculation apparatus 10 ends the process shown in the flowchart.

  In the present embodiment, the processes from step S11 to step S23 are executed continuously.

  Next, the Web page providing operation of the position information calculation apparatus according to the embodiment will be described with reference to FIG.

  The position information calculation device 10 determines whether there is an access request (step S21). The access request can be received from the terminal 20. If it is determined that there is no access request (step S21: NO), the position information calculation device 10 repeats the process of step S21 and waits for reception of the access request.

  On the other hand, if it is determined that there is an access request (step S21: YES), the location information calculation device 10 requests authentication information from the terminal 20 (step S22). After executing the process of step S22, the position information calculation apparatus 10 determines whether or not the authentication information is acquired (step S23). Acquisition of authentication information is received from the terminal 20. When it is determined that the authentication information is not acquired (step S23: NO), the position information calculation apparatus 10 repeats the process of step S23 and waits for the acquisition of the authentication information. If the authentication information cannot be acquired for a predetermined time or more, the position information calculation device 10 may stop the process.

  On the other hand, when it is determined that the authentication information is acquired (step S23: YES), the position information calculation device 10 determines whether the authentication is successful (step S24). If it is determined that the authentication has not succeeded (step S24: NO), the position information calculation apparatus 10 returns to the process of step S22 and requests authentication information again.

  On the other hand, when it is determined that the authentication is successful (step S24: YES), the position information calculation device 10 provides the terminal 20 with a Web page including the position information of the failure location (step S25). After executing the process of step S25, the position information calculation apparatus 10 ends the process shown in the flowchart.
