Description

  The present invention relates to a land use status application system that photographs a land use situation and applies an image with an attached image.

  The farmland has a low property tax rate, etc., instead of being approved for residential land, so the farmland owner can prove to the municipality that he is using the farmland as farmland. Apply for land use status.

  Application for land use, the owner of the farmland (applicant) takes a picture of the farmland, submits an application with an image (photo) attached, and then the person in charge (confirmer) of the municipality actually It is confirmed whether or not the farmland is used as farmland. Especially in recent years, there are farmland where vegetables are cultivated in buildings, such as hydroponics and plant factories. When fallowing, it is difficult to distinguish from concrete lands and commercial facilities. There is a growing need.

  Whether or not the farmland is properly used is determined by confirming that (1) the image is a photograph of the farmland and (2) the current situation. Here, the current situation is confirmed because it can be determined that the farmland has not been diverted to other uses when only a short period has elapsed since the time of shooting.

  By the way, the technique regarding the land and forest boundary management sensor system which recognizes the boundary with the owner of an adjacent land and a forest clearly is known (refer patent document 1). In this technology, the public boundary management pile with embedded IC tag is driven by the ubiquitous IT stick with built-in IC tag reader / writer when the pile driving work in the national land survey is performed. It identifies the location of the pile.

JP 2009-042001 A

  However, since the technique described in Patent Document 1 needs to drive public boundary management piles with embedded IC tags in the pile driving work in national land surveys, it is troublesome to apply to all farmland. There was a problem that the cost became enormous. In fact, it was necessary to go to land and forests.

  Accordingly, an object of the present invention is to provide a land use status application system in which it is possible to confirm that an image is a photograph of the farmland without the visitor visiting the farmland and the current situation. It is said.

  In order to achieve the above object, the invention described in claim 1 is a land use situation application system for photographing a land use situation and applying an image attached, and applying for the land use situation. A reporter-side device carried by the user, and a checker-side device that can communicate with the reporter-side device and accepts an application from the reporter-side device. Shooting means to which shooting time information can be added, position information acquisition means for acquiring shooting position information of a shooting location by the shooting means, an image shot by the shooting means, the shooting time information, and the position information Application means for transmitting the photographing position information acquired by the acquisition means to the confirmer-side device, the checker-side device having geospatial information such as the position and shape of the land, and the geospatial information. Acceptable mistakes A land information storage unit storing a geospatial error buffer indicating a range, a time error buffer indicating an allowable error range of the shooting time information, the image received from the reporter side device, and the shooting time information Based on the shooting position information, the geospatial information stored in the land information storage means, the geospatial error buffer, and the time error buffer, the shooting position information is within the range of the geospatial error buffer. And a determination means for determining whether or not the shooting time information is within the range of the time error buffer.

  According to the present invention, when the farmland is photographed by the photographing means of the reporter-side device and transmitted to the confirmer-side device, the image, the photographing time information, and the photographing received from the reporter-side device by the judging means of the confirmer-side device Based on the position information, the geospatial information stored in the land information storage means, the geospatial error buffer, and the time error buffer, the shooting position information is within the range of the geospatial error buffer, and the shooting time information is the time. It is determined whether it is within the error buffer.

  According to the invention described in claim 1, the applicant only has to photograph the farmland with the photographing means of the reporter-side device and transmit it to the confirmer-side device. By the means, it can be confirmed that the image is a photograph of the farmland and the current situation. That is, since it is not necessary for the confirmer to go to the farmland, labor and time required for work can be reduced.

  Further, for example, it is not necessary to install an IC tag or the like that stores farmland identification information for each farmland, so that it can be easily applied and introduced to all farmlands.

  Furthermore, since the determination unit uses the geospatial error buffer indicating the allowable error range of the geospatial information, if there is an error in the position information acquired by the position information acquisition unit, Even when it is slightly outside the farmland, it can be determined appropriately. In addition, since the determination unit uses the time error buffer indicating the allowable error range of the shooting time information, the time lag from shooting by the shooting unit to transmission by the application unit can be taken into account. Can be determined more appropriately.

  As shown in FIG. 14, the geospatial error buffer ΔA indicates an allowable error range of the geospatial information A. For example, “10 m” is stored for each reporter identification code of the owner of the farmland. In this case, even if the geographical attribute information (photographing position information) P of the image of the farmland is a position deviated by 10 m from the farmland, the image is a photograph of the farmland in the geographical attribute information comparison task STEP2102. It is determined that there is (“OK”). This geospatial error buffer ΔA can set an error range that can be set as an allowable error range, such as a nominal error of position acquisition by the GPS 22 or an error that occurs when the entire farmland is photographed from an adjacent land or road. it can. Thereby, for example, when another farmland is photographed, it is out of the range of the geospatial error buffer ΔA and is not allowed.

  As shown in FIG. 15, the time error buffer ΔT indicates an allowable error range of time information, and includes photographing time information (time attribute information) T1 and e-mail reception time information T2 by the transmission image acquisition task STEP2101. Is set as an allowable error range. The time error buffer ΔT sets an allowable error range based on the time required for the reporter to take an image and send it by e-mail, the time required for data falsification, etc., by the application task 251. be able to. Further, for example, for farmland in a place where radio waves do not reach such as a mobile phone, the time error buffer ΔT may be set larger than other farmlands. For example, “60 seconds” is stored in the time error buffer ΔT for each reporter identification code of the farm land owner. In this case, the shooting time information T1 and the e-mail reception time information T2 of the image of the farm land are stored. Even if there is a difference of 60 seconds, it is determined in the time attribute information comparison task STEP 2103 that the image capturing time is appropriate and the current situation (“OK”). For example, if the image was taken several months ago, it is out of the range of the time error buffer ΔT, the image taking time is invalid, and it is determined that the current situation is not (“NG”).

Has a function to save. Specifically, as shown in FIG. 10, it is determined whether or not the shooting position information P acquired in the transmission image acquisition task STEP2101 is within a range obtained by adding the geospatial information A and the geospatial error buffer ΔA. It has become. Here, for example, as shown in FIG. 14, when the shooting position information P is within the range obtained by adding the geospatial error buffer ΔA to the geospatial information A (inside the one-dot chain line), the received image represents the farmland. It is determined that the photograph was taken (“OK”), and otherwise, it is determined that the farmland was not photographed (“NG”).

  The time attribute information comparison task STEP2103 determines whether or not the received image is a photograph of the current situation of the farmland, and the determination result is the time attribute information comparison determination result of the processing code in the farmland information storage database 31a. It has a function to save. Specifically, as shown in FIG. 11, it is determined whether or not the shooting time information T1 and the e-mail reception time information T2 acquired in the transmission image acquisition task STEP2101 are included in the range of the time error buffer ΔT. It is supposed to be. That is, it is determined whether an error (time lag) between the shooting time information T1 and the e-mail reception time information T2 is within an allowable range, and an e-mail is transmitted at a sufficiently short time interval from the image shooting time information T1. It is determined whether or not it has been done. For example, as shown in FIG. 15, when the shooting time information T1 and the e-mail reception time information T2 that are time attribute information are within the range of the time error buffer ΔT (within the range indicated by the arrow), the received image is It is determined that the current state of the farmland is photographed (“OK”), and otherwise, it is determined that the current state of the farmland is not photographed (“NG”).

  The appropriate image confirmation task STEP 2104 has a function of determining whether or not the received image is appropriate as a farmland usage status application, and registering the determination result as an appropriate image confirmation result of the processing code of the farmland information storage database 31a. Have. Specifically, as shown in FIG. 12, it is determined whether or not both the geographical attribute information comparison determination result and the time attribute information comparison determination result of the processing code in the farmland information storage database 31a are “OK”. If both are “OK”, it is determined that the received image is appropriate as an application for use of farmland (“OK”). Otherwise, the received image is not appropriate as an application for use of farmland ( “NG”).

  As shown in FIG. 13, the result notification task STEP 2105 has a function of sending an e-mail to a predetermined e-mail address as to whether or not the received image is appropriate as a farmland utilization status application. Here, the predetermined e-mail address is the e-mail address of the confirmer, etc., and the determination result (“OK” for all the processing code images determined in the appropriate image confirmation task STEP 2104 together with the reporter identification code of the farm land owner. ”,“ NG ”) and the determination reason (for example,“ the received image is not a photograph of the current farmland ”,“ the received image is not a photograph of the current situation of the farmland ”, etc.) Then send.

  Next, the operation of the land use status application system having such a configuration will be described.

  First, the application from the reporter will be explained. At this time, the reporter carries the mobile phone terminal 2 and goes to the farmland where the use status application is made. Then, when arriving at the farmland, the application task 251 of the mobile phone terminal 2 is activated.

As shown in FIG. 5, in this image transmission task STEP105, in step 401, the e-mail application of the mobile phone terminal 2 is activated, and in step 402, the image captured by the digital camera 21 and stored in the memory is converted into an e-mail. At STEP 403, an image is attached to the e-mail and transmitted to a predetermined e-mail address of the confirmer set in the confirmer-side apparatus 3. The transmitted e-mail and image are stored in a predetermined folder when the checker-side device 3 receives the e-mail.

  Next, the confirmation by the confirmer of the usage status application applied by the reporter will be described.

  First, when registering farmland etc. information in the confirmer side device 3, as shown in FIG. 6, a farmland etc. geospatial information registration task 341 is started in STEP1101. As shown in FIG. 7, the farmland geospatial information registration task 341 has a reporter identification code for identifying a reporter registered in STEP 1201, and in STEP1202, the geospatial information of farmland owned by the reporter is registered. A is registered (added), and in STEP 1203, the geospatial error buffer ΔA of the farmland is registered (added). In STEP1204, the time error buffer ΔT of the farmland is registered (added), and the farmland etc. information storage database 31a is registered. Is registered and updated. This geo-spatial information registration task 341 such as farmland needs to be performed before the determination task 342 is activated.

  Next, the operation unit 33 of the confirmer side device 3 is operated by the confirmer, and the determination task 342 is activated.

  First, as shown in FIG. 8, a transmission image acquisition task is activated in STEP 2101. As shown in FIG. 9, the transmission image acquisition task STEP 2101 receives an e-mail transmitted from the mobile phone terminal 2 and an attached image in STEP 2201. In STEP 2202, a processing code is assigned to store information such as farmland. A record of the processing code is created in the application information in the database 31a. In STEP 2203, the e-mail reception time information T2 is confirmed, an error check is performed, and it is stored as application information in the farmland information storage database 31a. In STEP 2204, the reporter identification code is confirmed based on the contents described in the e-mail, an error check is performed, and the information is stored as application information in the farmland information storage database 31a. In STEP 2205, the attached image is confirmed and an error check is performed and stored as application information in the farmland information storage database 31a. In STEP 2206, the Exif position information tag is confirmed and error checked, and the farmland information storage database. It is stored as application information 31a. In STEP 2207, the Exif time information tag is confirmed, an error check is performed, the application information is stored in the farmland information storage database 31a, and the process ends.

  Then, in STEP 2102, the geographic attribute information comparison task is activated. As shown in FIG. 10, in the geographic attribute information comparison task STEP2102, the reporter identification code of the corresponding processing code is confirmed based on the farmland information storage database 31a in STEP2301, and in STEP2302, the geospatial information of the corresponding farmland etc. A is acquired, in STEP 2303, the geospatial error buffer ΔA of the corresponding farmland, etc. is acquired, in STEP 2304, the geographic attribute information (shooting position information) P of the corresponding processing code is acquired, and in STEP 2305, a comparison determination is performed. It is determined whether or not the shooting position information P is included in the range obtained by adding the geospatial information A and the geospatial error buffer ΔA. That is, it is determined whether the image is taken on the farmland or the like. If it is included (in the case of “YES”), the process proceeds to STEP 2306, and the fact that the geographical attribute information comparison determination result was “OK” is saved as application information in the farmland etc. information storage database 31a, and the processing is performed. finish. In STEP 2305, if it is not included (in the case of “NO”), the process proceeds to STEP 2307, and the fact that the geographical attribute information comparison determination result is “NG” is saved as application information in the farmland information storage database 31a. Then, the process ends.

  Here, for example, as shown in FIG. 14, when the shooting position information P is within the range obtained by adding the geospatial information A and the geospatial error buffer ΔA (inside the geospatial error buffer ΔA in FIG. 14), in STEP 2305 , It is determined that it is included (“YES”). If the shooting position is outside the range obtained by adding the geospatial information A and the geospatial error buffer ΔA (outside the geospatial error buffer ΔA in FIG. 14), it is not included in STEP 2305 (“NO”). Determined.

  In STEP 2103, a time attribute information comparison task is activated. In this time attribute information comparison task STEP2103, as shown in FIG. 11, the reporter identification code of the corresponding processing code is confirmed in STEP2401, and the time error buffer ΔT is obtained from the farmland information storage database 31a of the farmland in STEP2402. In STEP 2403, the photographing time information T1 is acquired from the application information in the farmland information storage database 31a for the farmland. In STEP2404, the e-mail reception time information T2 is acquired from the application information in the farmland information storage database 31a for the farmland. Then, in STEP 2405, a comparison determination is performed, and it is determined whether or not the shooting time information T1 and the e-mail reception time information T2 are included in the range of the time error buffer ΔT. That is, it is determined whether the image is in the current situation. If it is included (in the case of “YES”), the process proceeds to STEP 2406, the fact that the time attribute information comparison determination result is “OK” is stored in the farmland information storage database 31a, and the process ends. Also, in STEP 2405, if it is not included (in the case of “NO”), the process proceeds to STEP 2407, and the fact that the time attribute information comparison determination result is “NG” is stored in the farmland information storage database 31a and processed. Exit.

  Here, for example, as shown in FIG. 15, when the shooting time information T1 and the e-mail reception time information T2 which are time attribute information are within the range of the time error buffer ΔT, they are included in STEP 2405 (“ YES "). If the shooting time information T1 and the e-mail reception time information T2 are outside the range of the time error buffer ΔT (outside the time error buffer ΔT in FIG. 15), they are not included in STEP 2405 (“NO”). It is determined.

  In STEP 2104, the appropriate image confirmation task is activated. As shown in FIG. 12, in the appropriate image confirmation task STEP2104, in STEP2501, it is determined whether the geographic attribute information comparison determination of the processing code is “OK” or “NG”. If “NO”, proceed to STEP 2504. In the case of “OK” (in the case of “YES”), the process proceeds to STEP 2502, in which it is determined whether or not the time attribute information comparison determination of the corresponding processing code is “OK”, and in the case of “NG” (“NO”). In the case of), the process proceeds to STEP 2504. In the case of “OK” (in the case of “YES”), the process proceeds to STEP 2503, the fact that the proper image confirmation result is “OK” is registered in the farmland information storage database 31a, and the processing is ended. Further, in STEP 2501 and STEP 2502, the fact that the proper image confirmation result is “NG” is stored in the farmland information storage database 31a, and the processing is ended.

  In STEP 2105, the result notification task is activated. As shown in FIG. 13, in this result notification task, the result destination is confirmed in STEP 2601, the appropriate image confirmation result of the corresponding processing code is described in STEP 2602, and an e-mail is transmitted in STEP 2603 to complete the process. To do.

  As described above, according to the land use status application system 1, the applicant only has to photograph the farmland with the digital camera 21 of the mobile phone terminal 2 and transmit it to the confirmer side device 3. The determination task 342 of the checker side device 3 can confirm that the image is a photograph of the farmland and is in the current state. That is, since it is not necessary for the confirmer to go to the farmland, it is possible to reduce the labor and time required for the confirmation work for the land use status application.

  As described above, since the labor and time required for the land use status application confirmation work can be reduced, for example, even if the land use situation is applied every month, the work burden on the confirmer does not increase greatly. For this reason, even if it is a case where a land use situation is performed for every short period, possibility that the information regarding application will be tampered with, such as illegally diverting farmland after application, can be excluded.

  Further, since it is not necessary to install an IC tag or the like that stores identification information of the farmland for each farmland, it can be easily applied and introduced to all farmlands. In particular, if the reporter uses the mobile phone terminal 2 having the digital camera function, it is not necessary to introduce a new device, so that the reporter can easily introduce the reporter.

  Furthermore, since the determination task 342 uses the geospatial error buffer ΔA indicating the allowable error range of the geospatial information A, the position information acquired by the GPS 22 has an error or the shooting position is applicable. Even if it is slightly outside the farmland, it can be determined appropriately. In addition, since the determination task 342 uses the time error buffer ΔT indicating the allowable error range of the shooting time information T1, the time lag from the shooting by the digital camera 21 to the transmission by the application task 251 is considered. Therefore, it is possible to determine more appropriately.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, the mobile phone terminal 2 has been described as a mobile phone terminal with a camera function. However, the digital camera 21, the GPS 22, and a terminal device (personal computer) that transmits an e-mail are configured separately. May be. It is only necessary that the functions are logically assembled, and it does not matter whether the devices that realize the functions are physically in the same device or the like. The same applies to the confirmer side device 3.

  Moreover, although the form which mounts the interface for transmitting an image as "electronic mail" was demonstrated, an interface is not restricted to this. For example, an application-specific WEB page may be accessed and an image may be transmitted through the Internet.

  Furthermore, for each task step, for example, a confirmation message about whether or not to proceed to the next process is displayed on the operation unit 24 of the mobile phone terminal 2, and when the confirmation button is pressed, the next process (step) is performed. You may make it go.
