[Problems to be solved by the invention]
However, in order to monitor a moving monitoring object in a wide range in a tracking manner, a large number of installation cameras are required. The installation of such a large number of cameras is not practical from the viewpoint of cost and from the viewpoint of securing the installation location. If the number of camera installation locations is reduced, blind spots will increase.
[0006]
The present invention has been made in such a background, and the purpose of the present invention is to use a portable terminal device with a camera possessed by an unspecified number of users without using a large number of fixed installation cameras. An object of the present invention is to provide a report material information collection system, a camera-equipped mobile terminal device, and a server capable of continuously collecting information.
[0007]
[Means for Solving the Problems]
A reported matter information collection system according to the present invention is a reported matter information collection system in which a plurality of camera-equipped mobile terminal devices (camera terminals) and a server are connected to each other via a communication network. Each camera terminal includes camera photographing means, Position detecting means and data communication means are provided. The first camera terminal, according to the user's instruction, shoots the notification object by the camera photographing means, and the data communication means, as the first notification information, the photographed image of the first camera terminal, the photographing time, The position information detected by the position detecting means is transmitted to the server. The server includes data communication means and data storage means, stores the first notification information in the data storage means, and at least the data communication means with respect to camera terminals located in the vicinity based on the position information. Send a captured image and request a second report. The second camera terminal, which may include the first camera terminal, shoots a notification object recognized from the captured image in accordance with a user instruction in response to the request for the second notification, and as second notification information, The photographed image, photographing time, and position information of the second camera terminal are transmitted to the server. The server accumulates the second report information in the data storage means, and requests further second reports to camera terminals located in the vicinity based on the position information included in the second report information, Further second notification information returned from the camera terminal is stored in the data storage means.
[0008]
When the first notification information including the captured image, the shooting time, and the position information of the notification object is transmitted from the first camera terminal to the server, the first notification information is transmitted to the camera terminals around the position of the first camera terminal. The photographed image included in is transmitted and a request for the second notification is made. In response to this, the user of the second camera terminal shoots the notification object, and transmits a new captured image, shooting time, and position information to the server as second notification information. A further request for a second report can be made based on the second report information. In this way, it is possible to use camera terminals possessed by an unspecified number of users, and it is possible to continuously collect information on reported objects without using a large number of fixed installation cameras.
[0009]
The position information detected by the position detecting means is, for example, position information determined by a base station area for wireless communication, and the surroundings are, for example, the base station area in which the report is made and the adjacent base station area.
[0010]
The position detecting means may be a GPS receiving means. In this case, the position information is position information detected by the GPS receiving means.
[0011]
The first and second report information may also include reporter identification information. As a result, the server side can contact the reporter, and reports by mischief are suppressed.
[0012]
A camera-equipped mobile terminal device (camera terminal) according to the present invention includes a camera photographing means, a communication means for connecting to a communication network for data communication, a position detecting means for detecting the current position of the camera terminal, and a control means. Is provided. The control means shoots a notification object by the camera photographing means in accordance with a user instruction, and the communication means detects the photographed image by the camera photographing means, the photographing time, and the position detecting means as first notification information. The received position information is transmitted to the server, and according to the user's instruction in response to the second notification request from the server, the notification object recognized from the captured image is photographed, and the photographing is performed as the second notification information. The image, shooting time, and position information are transmitted to the server.
[0013]
The server according to the present invention is a server connected to a plurality of camera-equipped mobile terminal devices (camera terminals) through a communication network, and connects to the communication network to perform data communication, and stores data. Data storage means and control means are provided. When the control means receives from the first camera terminal, as the first notification information, a photographed image of the first camera terminal, a photographing time, and position information detected by the position detection means, the first notification information is received. Information is stored in the data storage means, and based on the position information, at least the photographed image is transmitted by the data communication means to a camera terminal located in the vicinity thereof to request a second notification, and the first camera When a captured image, a photographing time, and position information of the second camera terminal are received as second report information from a second camera terminal that may include a terminal, the second report information is stored in the data storage unit. Based on the position information included in the second notification information, a further second notification is requested to a camera terminal located in the vicinity thereof, and the second notification information responded from the camera terminal Storing in the data storage means.
[0014]
The data storage means includes, for example, a first report information management table that manages the first report information and a second report information management table that manages the second report information.
[0015]
The control means may request the further second notification only for a plurality of the second notifications selected according to a predetermined condition. This serves to limit the number of second notifications that can increase in the mouse formula.
[0016]
The present invention can also be grasped as a computer program that realizes the functions and means of the camera terminal and server and a recording medium thereof.
[0017]
DETAILED DESCRIPTION OF THE INVENTION

Request registration. The location registration station 4 is connected to the control station 1 and a gateway (mobile communication gateway station) 6 and registers, for each terminal, its terminal ID, telephone number, billing information, and information on the current base station area, to manage.
[0020]
FIG. 2 shows a configuration example of the camera terminal 10 in the present embodiment. The overall operation of the camera terminal 10 is controlled by the CPU 220. The CPU 220 is connected to the communication unit 203, the display control unit 209, the operation unit 206, the ROM 207, and the RAM 208 via the control line 200, and controls these units. The communication unit 203 is a part that performs transmission / reception processing of a mobile phone, and is connected to the base station by the antenna 202 via a wireless interface. The display control unit 209 is a part that performs display control of the display unit 210 such as a liquid crystal display. The operation unit 206 includes a numeric keypad and various operation keys, and is a part that receives user input instructions. The ROM 207 is a memory that stores a fixed program executed by the CPU 220 and fixed data associated therewith. The ROM 207 may include a rewritable nonvolatile memory such as a flash memory. A RAM 208 is a memory that provides a temporary storage area and a work area for data to be used by the CPU 220.
[0021]
The data line 201 is connected to the communication unit 203, the display control unit 209, the ROM 207, the RAM 208, the speaker 204, and the microphone 205, and provides a data transfer path between these arbitrary parts.
[0022]
FIG. 3 shows a configuration example of the server 50 in FIG. The overall operation of the server 50 is controlled by the CPU 310. The memory 311 is a main memory used by the CPU 310. The memory 311 is connected to the CPU 310 via the bus 330. An input device 314 such as a keyboard, a display device 315 such as a CRT and a liquid crystal display, and an external storage device 316 such as a hard disk device, MO, and CD-ROM are connected to the bus 330 via an interface 313.

Further, the bus 330 is connected to the microphone 341 and the speaker 342 via the audio input / output unit 340.
[0023]
FIG. 4 shows a configuration example of the control station 1. The overall operation of the control station is controlled by the CPU 410. A memory 411 is a main memory used by the CPU 410. The communication unit 420 is a communication unit that communicates with the base station 10 and the gateway 6. The external storage device 416 is a large-capacity storage device. Although not shown, the configuration of the location registration station 4 is substantially the same as that of the control station 1.
[0024]
Hereinafter, the operation of the present embodiment will be described.
[0025]
As shown in FIG. 5, in a mobile communication system of a mobile phone, a plurality of base stations A to J are responsible for each communication area, and even if a terminal that is a mobile station moves, within the communication area of any base station If so, communication is possible. Further, the terminal itself can recognize the base station area to which the terminal itself belongs, and the position of the current terminal is managed by the position registration station. In the present invention, it is assumed that camera terminals are widely spread and there are persons who have such camera terminals in any base station area.
[0026]
The movement monitoring object (report object) in the present invention is an arbitrary object that can be photographed by a camera and whose position can be changed over time, and can be a person, an object, an animal, a vehicle, or the like. Now, it is assumed that the monitoring object 71 is generated or found in the area of a certain base station B shown in FIG. 5 and has moved to the area of the base station G via the area of the base station C and the area of the base station F. To do.
[0027]
When the camera terminal user B1 in the area of the base station B finds the report object 71, the camera terminal user B1 reports to the server 50 (see FIG. 1) using his / her camera terminal 10. At this time, the user activates the emergency contact mode provided in the camera terminal by a predetermined operation such as menu selection or predetermined button instruction. Thereby, for example, a “first notification screen” as shown in FIG. 6A is displayed on the camera terminal. On this screen, a message such as “Shooting the report will automatically notify the center. There may be a confirmation message later.” Is displayed. At this time, the camera is ready to shoot, and when the user points the camera at the subject and presses the shutter button, shooting is performed. When the cancel button is instructed, the emergency contact mode is canceled.
[0028]
After shooting the report object, as shown in FIG. 6 (b), the captured image is displayed on the display screen of the terminal together with a message for confirming whether or not to report the next image. Is displayed. This screen information is associated with information for accessing the server. When the user instructs the OK button, the camera terminal accesses the server 50 based on the information and makes a first notification. The first report is a report when the camera terminal user voluntarily reports, and is distinguished from the second report reported by a request from the server 50 described later. The contents of the first report are a captured image, a shooting time, base station information (identification information of a base station area where the terminal is currently registered), and a reporter ID. In this embodiment, base station information constitutes position information. Here, the reporter ID is reporter identification information that can be used for the server side to identify the user and to contact the user, such as the phone number of the camera terminal and the e-mail address.
[0029]
The first report from the terminal to the server can be made by electronic mail. In this case, it is assumed that the contact e-mail address of the server 50 is stored in advance in the terminal when the application for emergency communication is installed. In this example, when the OK button is instructed on the screen shown in FIG. 6B after the emergency contact mode is activated, the photographed image file is attached to the mail and the mail is sent to the server. For generation of this mail, a template in which a destination, a subject, a transmission source, and a text (regular message and preferably a phone number of a terminal) are associated other than a photographed image can be used.
[0030]
However, any communication protocol other than e-mail may be used as long as the content of the first report can be transmitted to the server. For example, the server 50 may be a Web server, and a prescribed message and captured image may be transferred to the server 50 after accessing the server 50 from a terminal using the http protocol.
[0031]
In the server 50 that has received the first notification, the person in charge preferably checks the captured image to determine whether or not it is a notification worthy of tracking. If necessary, contact the user who made the first report and confirm the circumstances. Moreover, the case where a 1st report is performed independently from a separate camera terminal about the same report thing is also considered. In such a case, you may make it narrow down the 1st report used as emergency communication object to one. A plurality of first notification information may be stored. If such a report can be automatically determined by the server, the person in charge is not required. Instead of doing automatically, the server can operate based on the input of the judgment result of the person in charge.
[0032]
The server 50 adds a unique first report number and captured image ID to the first report that is determined to be at least necessary to be tracked, as well as a base station ID, a shooting time, and a reporter ID as first report information. For example, the information is registered in the first notification information management table 81 provided in the external storage device 316 as shown in FIG. FIG. 10 is a diagram showing a configuration example of a database used in the present embodiment. The image data 83 corresponding to the photographed image ID is given a unique photographed image ID and stored in the external storage device 316. “Reporter ID” in FIG. 10 is the reporter ID described above or information associated therewith.
[0033]
When it is determined that the report of the first report is worth tracking, the server 50, as shown in FIG. 7, determines the base station (base station B in this example) identified by the base station information notified by the first report. ) And a base station adjacent thereto (in this example, base stations A, E, F, C, I, and H) perform broadcast communication requesting at least a second notification to the camera terminal. In the example of FIG. 7, the hatched base station area is the contact range. This broadcast communication allows the control station of the base station to transmit an emergency communication signal to the terminal in the base station by using, for example, a common control channel, while the terminal responds to this, A screen including a predetermined message such as “Please cooperate with the second notification” as shown in FIG. 8A is displayed. This screen information is associated with information for accessing the server. A terminal without a camera does not respond because it does not have a function to respond to the emergency contact signal.
[0034]
If the user indicates the No button on the screen of FIG. If you indicate the Yes button, the terminal automatically accesses the server 50 and says “If you find the next image, please shoot with the camera. You may be contacted later for confirmation.” Such a regulation message and the image data of the first notification are received. An example of this is shown in the screen of FIG. When a cancel button is instructed on this screen, cooperation is refused or the screen returns to the screen of FIG. When the OK button is instructed, a shooting standby state is entered. When shooting is performed, a screen as shown in FIG. 8C is displayed. Similar to the case of FIG. 6B, second notification information including a new captured image is transmitted to the server in response to an instruction of the OK button. FIG. 9 shows an example in which the user C2 in the base station C makes the second notification.
[0035]
Note that, for emergency communication from the server to the terminal (also as a second notification request), an e-mail with a captured image attached to the terminal can be used instead of using the common control channel. In this case, the mail address of the user in the contact base station area is selected from the registered mail addresses of the users who cooperate with the service in advance as the mail address of the transmission destination.
[0036]
In the server 50 that has received the second notification information, the person in charge preferably checks the captured image to determine whether it is the same as the tracked object in the first notification. If necessary, contact the user who made the second report to confirm the circumstances. If such a determination can be made automatically at the server, the intervention of the person in charge is unnecessary. Alternatively, even if it is sufficient to verify the report history afterwards including misinformation, etc., the intervention of the person in charge is unnecessary. The server 50 adds a unique second report number and photographed image ID to the photographed image determined to be the same as the tracked object in the first report, and adds these to the first report number, base station ID, and photographed image. The second report information is registered in the second report information management table 82 provided in the external storage device 316 as shown in FIG. The image data 83 corresponding to the photographed image ID is given a unique photographed image ID and stored in the external storage device 316, like the image data of the first report.
[0037]
Thereafter, the server 50 makes emergency contact again according to the instruction of the person in charge. At that time, if the base station area where the tracked object is changed (for example, if the base station B has moved from the base station B to the area of the base station C as shown in FIG. 9), the contact base station is updated. To do.
[0038]
The user's report in response to the emergency communication should be called the third report. However, since the report is substantially the same as the second report, in this specification, the third report and subsequent reports are all referred to as “second report” for convenience. Call. However, the third and subsequent ordinal numbers are used for distinction. After the third notification, the captured image notified by emergency contact may be replaced with the captured image of any previous notification. If the appearance of the notification object changes over time, this replacement allows a more current appearance to be used for emergency communication. The selection of a new image used for replacement may be performed automatically, or the person in charge may select a more appropriate image.
[0039]
As described above, the captured image and the position information of the notification object that has started tracking by the first notification are sequentially accumulated in the server 50 together with the time information. If the tracked item is related to a dangerous item, a crime, or the like, the authorities can use this data to quickly respond.
[0040]
A processing flow related to the present embodiment of the next server and camera terminal will be described.
[0041]
FIG. 11 is a flowchart showing the first notification process of the camera terminal.
[0042]
When the user of the camera terminal finds an object to be reported, as described above, the terminal shifts to the first notification mode according to the user's first notification instruction operation (S11, Yes) (S12). . At this time, the first notification screen as described with reference to FIG. If there is a cancel instruction (S13, Yes), the process returns to step S11. When the shutter of the camera is turned on according to the user operation (S14, Yes), a confirmation screen as described in FIG. 6B is displayed (S15). If there is an OK instruction from the user (S16, Yes), the first notification including the above-described contents is sent to the server (S17). Thereafter, the first notification mode is automatically canceled (S18). As described above, when the first report from the terminal to the server is performed by e-mail, the first report screen information in step S12 is prepared in the camera terminal and is performed offline. On the other hand, when the first notification is made to the Web server, the first notification screen can be received from the server.
[0043]
FIG. 12 is a flowchart showing the report information collection process executed by the server.
[0044]
When the server receives the first notification (S31, Yes), based on the content of the notification, the server determines whether it should be tracked automatically or based on the input instruction of the judgment result of the person in charge. . If this determination result is “tracking required” (S32, Yes), the content of the first notification is registered in the first notification information management table 81 (FIG. 10), and the captured image data is accumulated (S33). Specifically, a first report number and a captured image ID are assigned to the first report and registered in the first report information management table 81 together with the received base station information and shooting time information. Next, a contact base station to be contacted by emergency is determined (S34). As described above, this applies to the base station area in which the first report is made and its adjacent base station area. However, these areas are examples of “periphery”, and the present invention is not limited to this. The server performs emergency communication (request for the second report) to all terminals of these base stations (S35).
[0045]
The terminal that has received emergency communication displays a screen as shown in FIG. 8A as described above. On the other hand, if the user gives a Yes instruction, the terminal accesses the server. The server interprets this access as a response that the user offers to cooperate (cooperation permission response) (S36, Yes), and the screen information for the second notification as shown in FIG. Transmit (S37). When camera photography is executed at the terminal and an OK instruction is given on the screen as shown in FIG. 6C, information of the second notification is transmitted to the server. When the server receives this information (S38, Yes), it determines whether the second report information is valid automatically or based on the input instruction of the determination result of the person in charge (S39). This step may include not only determining the validity of the second report information itself, but also a process of determining that the redundant second report information is invalid. For example, for the second report having the same base station ID, the second report information exceeding a predetermined number can be ignored as invalid. In that case, it is preferable to accumulate the second notification information of the newer time and discard the old second notification information.
[0046]
If it is determined in step S39 that the second notification information is valid, the content of the second notification is registered in the second notification information management table 82 (FIG. 10) and the captured image data is stored ( S40). Specifically, a second report number and a captured image ID are assigned to the second report, and are registered in the second report information management table 82 together with the received first report number, base station information, and shooting time information. If the person in charge gives an instruction to end (S41, Yes), the process returns to the first step S31. For the same first notification, if the subsequent second notification is interrupted for a predetermined time or more, it may be automatically determined that the process has ended, and the process may return to step S31. If not, it is determined whether emergency communication is to be performed for the second notification (S42). When multiple effective second notifications occur within a short time, it is useless to make emergency contact for all of them, and it complicates the response on the server. This is because it is not used as a trigger for emergency communication (second report request). This determination may be made by the person in charge, but can also be made automatically based on time determination or the like. For example, when there are a plurality of valid second notifications within a predetermined unit time, processing such as using one of them as a trigger for a further second notification request can be considered. At this time, the second notifications with different base station IDs may overlap. In that case, processing such as selecting the second notification with the newest time, selecting the most base station ID among the accumulated second notifications, and a compromise between the two is performed.
[0047]
If it is determined that an emergency contact is required, that is, a second report request is made, a contact base station is further determined (S43), and emergency contact is made to all terminals of the determined base station (S44). Otherwise, the process returns to step S31.
[0048]
FIG. 13 is a flowchart showing the second notification process of the terminal.
[0049]
Upon receiving emergency contact from the server (S51, Yes), the terminal displays an emergency contact screen as described with reference to FIG. 8A (S52). On the other hand, if there is an input to cooperate with the user (S53, Yes), the terminal requests the second notification screen information from the server (S54), as shown in FIG. 8B. Second report screen information is received from the server and displayed (S55). Next, the mode is shifted to the second notification mode, and the camera photographing mode is entered (S56). Thereafter, if there is no cancel instruction from the user (S57, No), when the shutter is turned on by a user operation (S58, Yes), a confirmation screen as shown in FIG. 8C is displayed (S59). . On the other hand, if a confirmation OK instruction is obtained from the user, the terminal makes a second report to the server (S61). As described above, the contents are the first report number, the captured image, the captured time, the base station information, and the reporter ID. After the execution of the second notification, the second notification mode is canceled (S62).
[0050]
FIG. 14 shows the configuration of a camera terminal according to another embodiment of the present invention. The hardware configuration of the server, control station, etc. is the same as in the first embodiment.
[0051]
The configuration of the camera terminal of the present embodiment is the same as the configuration shown in FIG. 2, but a GPS (Global Positioning System) communication circuit unit 214 and a GPS antenna 213 are added as position detecting means. The GPS communication circuit unit 214 is a part that receives radio waves from a GPS satellite in order to obtain latitude and longitude as current location information via the GPS antenna 213. In this embodiment, the position detection result of GPS is used as the position information reported from the terminal and managed by the server. Therefore, although not shown in the drawing, an item of “current position” of the terminal is provided in the first and second notification information management tables 81 and 82 (FIG. 10). The item of “base station ID” is left in order to specify the contact address for emergency communication (request destination of the second report). However, when requesting the second report by e-mail from the server to the terminal, the base station ID is not used to determine the contact address, and the GPS detection position is used to communicate within a predetermined radial distance from the current position. When the destination area is determined, the item “base station ID” is not necessary.
[0052]
In the present embodiment, by using the GPS position detection result as the position information, the position of the notification object can be tracked with higher accuracy.
[0053]
Although the preferred embodiments of the present invention have been described above, various modifications and changes can be made in addition to those mentioned above.
[0054]
For example, “emergency communication” has been described as an example, but the report target is not necessarily limited to “emergency (emergency)”.
[0055]
The second report for the first report is not distinguished from the second report for the second report and the second report for the second report. However, the third report, the fourth report,... You may make it accumulate | store the report information of each hierarchy in a server, distinguishing a report. In that case, for example, the server includes the hierarchy information indicating which level of the report the report request received by the terminal is based on, and causes the server to return the hierarchy information in response to the report. The hierarchy of notifications can be identified.
[0056]
The terminal is a mobile phone terminal, but may be a PHS (simple mobile phone) terminal. In the case of PHS, the range of the base station area of the mobile phone is narrow, and it is possible to grasp the position with higher accuracy than the mobile phone. The present invention can also be applied to a wireless LAN system instead of a telephone system.
[0057]
【The invention's effect】
According to the report material information collection system of the present invention, the following remarkable effects are obtained.
[0058]
1. By effectively using the mobile terminal device with camera and the existing communication network possessed by an unspecified number of users, the sighting information including the photographed image can be sequentially stored in the server together with the photographing time information. This information can be used effectively for the follow-up of the report.
[0059]
2. Since a portable terminal device with a camera owned by an unspecified number of users is used, it is possible to construct a relatively inexpensive report material information collection system.
[0060]
3. If a place where a person can pass within the communicable area, it is possible to take a picture even in a place where a camera cannot be physically or cost-effectively installed. Further, by obtaining the cooperation of a plurality of users, the blind spots can be greatly reduced as compared with the conventional system. In particular, when a mobile phone network is used, an extremely wide range can be set as a tracking target area of a report object.
[0061]
4). If the reported object is a dangerous substance, the request for the second report will be made in advance to an area where there is a possibility of danger, and functions as a warning to prevent new damage.
