The server includes a server transmission control unit that controls the first mobile terminal device and the second mobile terminal device to transmit the fact that the witness certificate data has been received when the witness certificate data is received.

According to such a land boundary confirmation system, the owner of the land confirming the boundary, that is, the witness who carries out the confirmation of the boundary of the land, is the first mobile terminal device even if he / she is staying in a remote place. It is possible to visually confirm the boundary by visually recognizing the image data regarding the boundary of the land taken by the photographing unit and transmitted to the second mobile terminal device and displayed on the second display unit of the second mobile terminal device. can. In addition, since the signature data can be input by the second input unit for the witness certificate data created by the first mobile terminal device, the witness certificate can be completed even if the witness does not go to the site. Can be done. Then, even if the owner of the land adjacent to the boundary does not go to the site to confirm the boundary, the boundary can be confirmed as a witness and the witness certificate can be completed. Therefore, it is possible to reduce the time burden and the financial burden when the witness goes to the land where the boundary is confirmed. In addition, since it is not necessary to consider the movement of witnesses, it is easy to coordinate the schedule between witnesses who witness the boundary of the land. Therefore, it is possible to efficiently promote the witnessing work of the land boundary. In addition, at the time of witnessing, the image data taken by the shooting unit is transmitted to the server and stored in the server storage unit. Regarding the image data stored in the server storage unit, it is difficult to falsify the data or correct the data by a malicious third party. Therefore, it can be guaranteed that the confirmation work of the land boundary is appropriate. Therefore, reliability can be improved. From the above, according to such a land boundary confirmation system, it is possible to reduce the burden on the witnesses and to carry out the system efficiently, and it is possible to improve the reliability.

It may further include a server output control unit that controls to superimpose the second pulse sound data different from the frequency of the first pulse sound data on the confirmation image data and output the data. By doing so, the image data for viewing can be specified based on the second pulse sound data having a frequency different from the frequency of the first pulse sound data. Therefore, the viewing image data and the viewer can be easily linked, and even if the viewing image data is falsified, it is easy to identify that the viewing image data is falsified. As a result, the reliability can be further improved.

In the land boundary confirmation system, the server storage control unit controls to receive the data transmitted from the first mobile terminal device and at the same time store the data transmitted from the first mobile terminal device in the server storage unit. You may. By doing so, the so-called real-time image data can be stored in the server storage unit. Then, the time for falsifying the image data can be restricted, and the reliability can be further improved.

The server storage control unit may control the image data relating to the boundary of the land to be associated with the position data of the first mobile terminal device acquired by the first position data acquisition unit and stored in the server storage unit. .. By doing so, it is possible to store the confirmation image data in association with the position data of the first mobile terminal device in which the image data is captured. Then, by comparing the position of the first mobile terminal device with the position of the boundary of the photographed land, it is possible to easily prove that the photographed image data is an image of the boundary of the land. Therefore, the reliability can be further improved.

In the above land boundary confirmation system, a judgment unit for determining whether or not an image of a boundary marker is included in the image data regarding the boundary of the land photographed by the photographing unit and an image of the boundary marker by the determination unit are included. If it is determined that the boundary marker is determined to be, a second position data acquisition unit for acquiring the position data of the boundary marker may be further provided. The server storage control unit may control the image data relating to the boundary of the land to be associated with the position data of the boundary marker acquired by the second position data acquisition unit and stored in the server storage unit.

Next, the flow of the land boundary confirmation work flow in the land boundary confirmation system 11 in the first embodiment will be described. FIG. 3 is a flowchart showing a part of the processing flow in the land boundary confirmation system 11 in the first embodiment. In the first embodiment, the server 21 is installed in the office of the management company 12. The first remote witness 14 who owns the tablet PC 31b and the second remote witness 15 who owns the tablet PC 31c have not gone to the site which is the land 48a where the boundary 47a is confirmed. The staff of the local witness 17, the practitioner 18 and the practitioner 18 are going to the site. In addition, with the camera 35a included in the tablet PC 31a owned by the local witness 17, the staff of the practical operator 18 can see the local image, that is, the still image of the land 48a confirming the boundary 47a, and the local witness 17 and the business. A video of the confirmation work of the boundary 47a of the land 48a by the handler 18 is taken. The image 43a of the land 48a confirming the photographed boundary 47a is displayed in the area 42a. The image 43b of the moving image of the confirmation work of the boundary 47a of the land 48a by the field witness 17 and the practitioner 18 is displayed in the area 42b.

First, in the land boundary confirmation system 11, it is determined whether or not the establishment of communication of all the participants has been confirmed (step S11 in FIG. 3, hereinafter "step is omitted"). Participants here are 17 local witnesses, 14 first remote witnesses, 15 second remote witnesses, and 18 practitioners. In this case, the establishment of mutual communication is confirmed by using the mail function, chat function, etc. of each tablet PC 31a, 31b, 31c. Here, if the establishment of communication is not confirmed (NO in S11) such as poor communication, an e-mail is transmitted from the tablet PC 31a to the tablets PC 31b and 31c owned by the remote witness whose communication is not confirmed (S12). .. If a timeout occurs without confirming the establishment of communication (YES in S13), the process ends. That is, the confirmation work of the boundary 47a of the land 48a is completed.

When the establishment of communication is confirmed (YES in S11), the confirmation work of the boundary 47a of the land 48a is started. Here, the image 43a of the region including the boundary 47a of the land 48a taken by the camera 35a is captured in the tablet PC 31a. That is, the tablet PC 31a acquires the image data of the boundary 47a of the photographed land 48a (S14). The captured image 43a is displayed as an image 43a in the area 42a of the touch panel 41a of the tablet PC 31a. The image 43a is similarly displayed on the touch panels 41b and 41c of the tablet PCs 31b and 31c, respectively.

After that, the video capture built in the server 21 is activated by the command from the tablet PC 31a (S15). Then, the camera 35a included in the tablet PC 31a starts recording the moving image data of the boundary confirmation work (S16).

Here, in the server 21 that has received the captured moving image data, the pulse sound data generation unit 25 generates the first pulse sound data (S17). The frequency of the generated first pulse sound data is 20 kHz or more. Specifically, for example, a frequency of 30 kHz or a frequency of 40 kHz is selected. The frequency of the generated first pulse sound data is preferably 96 kHz or less in consideration of the performance of the moving image editing device.

The first pulse sound data generated by the pulse sound data generation unit 25 may be the first pulse sound data having a constant frequency, or the frequency may be changed according to the timing to obtain the first pulse sound data. Pulse sound data may be generated.

Next, the captured moving image data is transmitted to the server 21 via the network 16 (S18). Further, the captured moving image data is also transmitted to each of the tablet PCs 31b and 31c. Here, the tablet PC transmission control unit 37a serves as a first transmission control unit that controls the server 21 and the tablet PCs 31b, 31c to transmit image data regarding the boundary 47a of the land 48a taken by the camera 35a via the network 16. Function.

Next, the confirmation image data creation unit 28 superimposes the first pulse sound data generated by the pulse sound data generation unit 25 on the image data transmitted from the tablet PC 31a and received by the server network interface unit 23 ( S19). In this case, the first pulse sound data is superimposed on the audio data in the image data. FIG. 4 is a graph showing an example of voice data on which the first pulse sound data is superimposed. The vertical axis shows the frequency (kHz), and the horizontal axis shows the elapsed time. With reference to FIG. 4, the voice data 61 is shown as a waveform in the region where the frequency is 20 kHz or less. The first pulse sound data 62 appears as a pulse signal at a frequency of 20 kHz or higher, specifically, for example, a frequency of 23 kHz. In this way, the first pulse sound data 62 is superimposed on the voice data 61. Since the first pulse sound is inaudible to the human ear, it cannot be understood that the first pulse sound data 62 is included in the confirmation image data only by viewing the confirmation image. It should be noted that this superposition is carried out until the confirmation work of the boundary of the land is completed and the creation of the confirmation image data is completed. The confirmation image data created by the confirmation image data creation unit 28 is stored in the server hard disk 24 by the server storage control unit 26. Here, the server storage control unit 26 controls to receive the data transmitted from the tablet PC 31a and to store the data transmitted from the tablet PC 31a in the server hard disk 24. Then, proceed to S20.

After that, the work to confirm the boundary of the land is carried out. FIG. 5 is a diagram showing an example of an image taken by the camera 35a of the tablet PC 31a during the confirmation work of the boundary 47b of the other land 48b. With reference to FIG. 5, on the touch panel 41a of the tablet PC 31a, two images 51a and 51b near the boundary 47b of the land 48b are displayed vertically side by side. In the upper region 51a, an image 51a of the land 48b in which only the vicinity of the boundary 47b including the fixed stud 46b is photographed is displayed. In this image, the distance from the fixed stud 46b to the utility pole is displayed. Further, a ponchi-e 53a on the side surface of the land 48b including the boundary 47b is displayed outside the area 51a. Further, in the lower region 51b, an image 51b in which witnesses 19a and 19b are actually present and the boundary marker 46c is confirmed is displayed. While displaying such image data on the tablet PCs 31b and 31c, even the witnesses 14 and 15 who are staying remotely can confirm the boundary.

FIG. 6 is a flowchart showing a part of the processing flow in the land boundary confirmation system 11 in the first embodiment. FIG. 6 shows the steps performed following FIG. With reference to FIG. 6 as well, when all the parties concerned are participating (YES in S21), it is determined whether or not the intention display data of all the participants has been received (S22). The manifestation of intention data is data indicating that the position of the boundary has been confirmed. This is accepted by inputting data by the first input unit or the second input unit. On the other hand, when all the parties concerned have not participated (NO in S21), that is, when the witnesses of the boundary do not meet the schedule at the timing of the meeting and participate in the time late, or the boundary is confirmed again at a later date. When doing so, it is determined whether or not the individual participant's manifestation data has been received (YES in S23). In any case, if the manifestation data cannot be received within a predetermined time (NO in S22, NO in S23, YES in S25), the process ends as a timeout. That is, the work is terminated assuming that the boundary confirmation work has been completed unsuccessfully.

When the boundary confirmation by the local witnesses 17 and the remote witnesses 14 and 15 is completed, the witness certificate data is created (S24). Specifically, the witness certificate data creation unit 38a included in the tablet PC 31a is an image data taken by the camera 35a, a first input data input by the touch panel 41a which is the first input unit, and a second input unit. Based on the second input data input by the touch panels 41b and 41c, the witness certificate data, which is the certificate data related to the witness of the land boundary, is created. The witness certificate is a certificate created based on the manifestation of intention when the witness confirms the boundary of the land. FIG. 7 is a diagram showing an example of witness certificate data. With reference to FIG. 7, the created witness certificate data 56 is displayed on the touch panel 41a of the tablet PC 31a. The attendance certificate data 56 can be input from the touch panel 41a of the tablet PC 31a. In this case, the electronic signature by the witness is input. In this way, the witness certificate data 56 in which the electronic signature by the witness is input is created.

Next, the tablet PC transmission control unit 37a transmits the created witness certificate data 56 to the server 21 (S26). That is, the tablet PC transmission control unit 37a, which is the first transmission control unit, controls to transmit the witness certificate data created by the witness certificate data creation unit 38a to the server 21. Then, when the server transmission control unit 27 included in the server 21 receives the witness certificate data, the witness certificate is given to the tablet PC 31a which is the first mobile terminal device and the tablets PC 31b and 31c which are the second mobile terminal devices. Controls to send the fact that the document data has been received. Specifically, when the server 21 receives the image data of the witness certificate (S27), the server 21 sends an e-mail to the persons concerned (S28). The persons concerned here are 17 local witnesses, 14 first remote witnesses, 15 second remote witnesses, and 18 practicing handlers.

The server 21 stores the confirmation image data recorded on the server hard disk 24 after the witnessing work is completed (S29). Then, after the signature input of all the persons concerned is completed, that is, after the witness certificate data is completed, the witness certificate data is transmitted by e-mail to all the persons concerned (S30). Here, by sending an e-mail with a read confirmation, it is recognized that the sent e-mail has been opened, that is, the recipient of the e-mail has confirmed the witness certificate data attached to the e-mail. Can be done.

According to the land boundary confirmation system 11 having such a configuration, the owner of the land that confirms the boundary, that is, the witness who performs the confirmation of the boundary of the land, is the camera of the tablet PC 31a even if he / she is staying in a remote place. The boundary can be confirmed by visually recognizing the image data relating to the land boundary taken by the 35a and transmitted to the tablet PCs 31b and 31c and displayed on the touch panels 41b and 41c of the tablet PCs 31b and 31c. Further, since the signature data can be input to the witness certificate data created by the tablet PC 31a using the touch panels 41b and 41c, the witness certificate can be completed without the witness going to the site. Then, even if the owner of the land adjacent to the boundary does not go to the site to confirm the boundary, the boundary can be confirmed as a witness and the witness certificate can be completed. Therefore, it is possible to reduce the time burden and the financial burden when the witness goes to the land where the boundary is confirmed. In addition, since it is not necessary to consider the movement of witnesses, it is easy to coordinate the schedule between witnesses who witness the boundary of the land. Therefore, it is possible to efficiently promote the witnessing work of the land boundary. Further, at the time of witnessing, the image data taken by the photographing unit is transmitted to the server 21 and stored in the server hard disk 24. Regarding the image data stored in the server hard disk 24, it is difficult to falsify the data or correct the data by a malicious third party. Therefore, it can be guaranteed that the confirmation work of the land boundary is appropriate. Therefore, reliability can be improved. From the above, according to such a land boundary confirmation system 11, it is possible to reduce the burden on the witnesses, to carry out the system efficiently, and to improve the reliability.

According to the land boundary confirmation system 11 described above, the burden on not only land owners and witnesses but also public offices that carry out public works projects is reduced when confirming the boundaries of land necessary for public works projects. It can also be implemented efficiently.

In the present embodiment, the server 21 has captured the pulse sound data generation unit 25 that generates the first pulse sound data and the first pulse sound data generated by the pulse sound data generation unit 25 by the camera 35a. It includes a confirmation image data creation unit 28 that superimposes on the image data to create confirmation image data. Further, the server storage control unit 26 controls the server hard disk 24 to store the first pulse sound data generated by the pulse sound data generation unit 25. Therefore, since the first pulse sound data is superimposed on the confirmation image data stored in the server 21, it can be easily determined whether or not the confirmation image data has been tampered with. Therefore, the reliability can be further improved.

In the present embodiment, the frequency of the first pulse sound data generated by the pulse sound data generation unit 25 is 20 kHz or more. Therefore, the confirmation image data can be created by superimposing the first pulse sound data having a frequency higher than the frequency of the sound that can be recognized by human hearing on the image data. Then, since the sound having a frequency of 20 kHz or higher is inaudible to the human ear, it is determined whether or not the confirmation image data includes the first pulse sound simply by viewing the confirmation image data. Can't. That is, when a third party who does not know that the first pulse sound data is included in the confirmation image data falsifies the confirmation image data, the first pulse sound data is deleted or interrupted. Therefore, the abnormality of the first pulse sound data is included. Then, it can be grasped that the image data is falsified for confirmation. Therefore, it can be easily determined whether or not the confirmation image data has been tampered with. As a result, reliability can be further improved.

In the land boundary confirmation system 11, the authorized viewer can browse the confirmation image data stored in the server hard disk 24 by requesting browsing. Here, the server 21 is generated by a receiving unit that accepts a request for viewing the confirmation image data stored in the server hard disk 24, and a pulse sound data generation unit 25 if the receiving unit receives a request for viewing the confirmation image data. Further, a server output control unit that controls to superimpose the second pulse sound data different from the frequency of the first pulse sound data on the confirmation image data and output the data may be included.

FIG. 8 is a flowchart showing a typical processing flow when a viewing request is accepted. With reference to FIG. 8, if the viewing request is accepted by the server 21, it is determined whether or not the viewing requester has the viewing authority (S41). In this case, it is determined whether the request is made by a registered related party or the like. If there is no viewing authority (NO in S41), a response is displayed indicating that the viewing request is rejected (S42), and the process ends. If it is determined that the user has viewing authority (YES in S41), the second pulse sound data is generated (S43). The frequency of the second pulse sound data is different from the frequency of the first pulse sound data. Then, the second pulse sound data is superimposed on the confirmation image data. FIG. 9 is a graph showing an example of voice data on which the second pulse sound data is superimposed. The vertical axis shows the frequency (kHz), and the horizontal axis shows the elapsed time. With reference to FIG. 9, in addition to the voice data 61 and the superimposed first pulse sound data 62, the second pulse sound data 63 is superimposed. The second pulse sound data 63 appears as a pulse signal at a frequency of 20 kHz or higher, specifically, for example, a frequency of 28 kHz. In this case, the frequency is different from the frequency of the first pulse sound data 62, and it appears as a different pulse signal. Since the first pulse sound and the second pulse are inaudible to the human ear, it can be seen that the first pulse sound data 62 and the second pulse sound data 63 are included in the viewing image data. You can't tell just by watching the image. In this way, the second pulse sound data 63 is superimposed on the voice data 61 and the first pulse sound data 62. It should be noted that this superimposition is carried out until the confirmation image data is completed. In this way, image data for viewing is created (S44). After that, the image data for viewing is stored in the server hard disk 24 (S45), and the image data for viewing is output to the viewing requester (S46).

By doing so, the image data for viewing can be specified based on the second pulse sound data having a frequency different from the frequency of the first pulse sound data. Therefore, the viewing image data and the viewer can be easily linked, and even if the viewing image data is falsified, it is easy to identify that the viewing image data is falsified. As a result, the reliability can be further improved.

(Other embodiments)
In the land boundary confirmation system 11, the pulse sound data generation unit 25 may generate the first pulse sound data at different frequencies at predetermined timings. By doing so, the first pulse sound data having a different frequency is superimposed at a predetermined timing, so that the data cannot be falsified unless the predetermined timing and the frequency at that time are grasped. Therefore, the reliability can be further improved. The same applies to the second pulse sound data.

Further, in the land boundary confirmation system 11, the pulse sound data generation unit 25 may generate the first pulse sound data at a frequency derived according to the generated random number. By doing so, it becomes more difficult to falsify the confirmation image data than to generate the pulse sound data whose frequency is changed according to some regularity. Therefore, the reliability can be further improved. The same applies to the second pulse sound data.

In the land boundary confirmation system 11, the server storage control unit 26 may control the server hard disk 24 to store the data transmitted from the tablet PC 31a at the same time as receiving the data transmitted from the tablet PC 31a. By doing so, the so-called real-time image data can be stored in the server hard disk 24. Then, the time for falsifying the image data can be restricted, and the reliability can be further improved.

Further, in the land boundary confirmation system 11, when the barcode data creation unit that creates the barcode data used when displaying the attendance certificate data and the barcode data created by the barcode creation unit are read, the attendance is performed. A display control unit that controls the display of certificate data may be further provided. By doing so, if the barcode is read, the witness certificate data can be displayed. Therefore, the witness certificate data can be easily displayed, that is, without inputting various data.

The land boundary confirmation system 11 may further include a first position data acquisition unit for acquiring the position data of the tablet PC 31a. The server storage control unit 26 may control the image data relating to the boundary of the land to be associated with the position data of the tablet PC 31a acquired by the first position data acquisition unit and stored in the server hard disk 24. By doing so, it is possible to store the confirmation image data in association with the position data of the tablet PC 31a in which the image data is captured. Then, by comparing the position of the tablet PC 31a with the position of the boundary of the photographed land, it is possible to easily prove that the photographed image data is an image of the boundary of the land. Therefore, the reliability can be further improved. Here, for example, the first position data acquisition unit may be included in the server 21. Further, regarding the acquisition of the position data by the first position data acquisition unit, the position data can be acquired by using the GPS (Global Positioning System) function built in the tablet PC 31a.

Further, the land boundary confirmation system 11 includes a determination unit for determining whether or not the image data relating to the boundary of the land taken by the camera 35a includes an image of the boundary marker, and an image of the boundary marker by the determination unit. If it is determined that the image is obtained, a second position data acquisition unit for acquiring the position data of the boundary marker may be further provided. The server storage control unit 26 may control the image data relating to the boundary of the land to be associated with the position data of the boundary marker acquired by the second position data acquisition unit and stored in the server hard disk 24. By doing so, it is possible to store the confirmation image data in association with the position of the boundary marker. Then, it is possible to easily prove that the captured image data is an image of the boundary of the land by comparing the position of the boundary marker with the position of the boundary of the land. Therefore, the reliability can be further improved. Here, for example, the second position data acquisition unit may be included in the server 21. Further, regarding the acquisition of the position data by the second position data acquisition unit, the position data can be acquired by using the GPS function built in the boundary marker.
