[Problems to be solved by the invention]
However, in order to monitor a moving monitoring target in a wide range, many 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 an installation place. Decreasing the number of cameras will increase blind spots.
[0006]
The present invention has been made in such a background, and an object of the present invention is to use a mobile terminal device with a camera possessed by an unspecified number of users, and to use a mobile terminal device with a large number of fixed installation cameras without using a large number of fixedly installed cameras. It is an object of the present invention to provide a report information collection system, a portable terminal device with a camera, and a server that can continuously collect information.
[0007]
[Means for Solving the Problems]
A report information collection system according to the present invention is a report information collection system in which a plurality of mobile terminal devices with cameras (camera terminals) and a server are connected to each other via a communication network. A position detecting unit and a data communication unit are provided. The first camera terminal, according to the user's instruction, shoots a notice by the camera photographing means, and the data communication means captures, as first notification information, a photographed image of the first camera terminal, a photographing time, The position information detected by the position detecting means is transmitted to the server. The server includes a data communication unit and a data storage unit, stores the first notification information in the data storage unit, and at least uses the data communication unit for a camera terminal located around the first notification information based on the position information. A photographed image is transmitted and a second report is requested. A second camera terminal, which may include the first camera terminal, performs photographing of a message recognized from the photographed image according to a user instruction in response to the request for the second report, and as second report information, The photographed image, photographed time, and position information of the second camera terminal are transmitted to the server. The server accumulates the second notification information in the data storage unit, and requests a further second notification to a camera terminal located therearound based on the position information included in the second notification information, Further second notification information returned from the camera terminal is stored in the data storage unit.
[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 near the position of the first camera terminal. Is transmitted, and a request for the second report is made. In response to this, the user of the second camera terminal takes a picture of the report, and transmits a new photographed image, a photographing time, and position information to the server as the second report information. A new request for a second report can be made based on the second report information. In this way, the camera terminals possessed by an unspecified number of users can be used, and it is possible to continuously collect information on the report without using a large number of fixedly installed cameras.
[0009]
The position information detected by the position detecting means is, for example, position information determined by a base station area of wireless communication, and the surroundings are, for example, a base station area that has been notified and a base station area adjacent thereto.
[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 report by mischief is suppressed.
[0012]
A portable terminal device with a camera (camera terminal) according to the present invention includes a camera photographing unit, a communication unit that connects to a communication network to perform data communication, a position detection unit that detects a current position of the camera terminal, and a control unit. Is provided. In accordance with a user's instruction, the control unit captures a notification by the camera capturing unit, and detects, by the communication unit, a captured image by the camera capturing unit, a capturing time, and the position detection unit as first notification information. The server transmits the position information obtained to the server, and in accordance with a user's instruction in response to a request for a second report from the server, performs photographing of a report object recognized from the photographed image. The image, the photographing time, and the position information are transmitted to the server.
[0013]
A server according to the present invention is a server that is mutually connected to a plurality of mobile terminal devices with cameras (camera terminals) via a communication network. The server is connected to the communication network to perform data communication, and stores data. Data storage means and control means are provided. This control means, when receiving, from the first camera terminal, as the first notification information, a captured image of the first camera terminal, a shooting time, and the position information detected by the position detection means, Information is stored in the data storage means, and at least the photographed image is transmitted by the data communication means to a camera terminal located therearound based on the position information to request a second report, and the first camera When receiving, as second notification information, a captured image, a shooting time, and position information of the second camera terminal from a second camera terminal that may include a terminal, the second notification information is stored in the data storage unit. Requesting a further second report to a camera terminal located therearound based on the position information included in the second report information, and transmitting the second report information responded from the camera terminal in advance. Storing in the data storage means.
[0014]
The data storage unit 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 report only for one selected from a plurality of the second reports in accordance with a predetermined condition. This serves to limit the number of second messages that can increase in the mouse formula.
[0016]
The present invention can be further understood as a computer program for realizing the functions and means of the camera terminal and the server and a recording medium thereof.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION

In this specification, the camera-equipped mobile terminal device is simply referred to as a camera terminal or a terminal.
[0019]
FIG. 1 shows only two camera terminals 10A and 10B as camera terminals. However, the camera terminal in the present invention is owned by an unspecified number of users, and there are actually many camera terminals. The camera terminal 10A and the camera terminal 10B can mutually communicate voice and data via the base stations 2A and 2B and the control station 1. The camera terminal 10 is connected to the public line network 8 via the base station 2, the control station 1, and the gateway 6, and can access the server 50. The terminal monitors the location registration area information constantly output from the base station, recognizes the base station area to which the terminal belongs, and notifies the location registration station 4 via the base station 10 and the control station 1 of its own current information. Request registration. The location registration station 4 is connected to the control station 1 and the gateway (mobile communication gateway station) 6, and registers, for each terminal, a terminal ID, a telephone number, charging information, and information on a base station area where the terminal is currently located. to manage.
[0020]
FIG. 2 shows a configuration example of the camera terminal 10 according to 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 unit that performs transmission / reception processing of a mobile phone, and is connected to a base station via a wireless interface by an antenna 202. The display control unit 209 is a unit 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 a user's input instruction. The ROM 207 is a memory that stores a fixed program executed by the CPU 220 and fixed data attached thereto. The ROM 207 may include a rewritable nonvolatile memory such as a flash memory. The RAM 208 is a memory that provides a temporary storage area and a work area for data 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 storage 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, an MO, and a 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 entire operation of the control station is controlled by the CPU 410. The memory 411 is a main storage memory used by the CPU 410. The communication unit 420 is a communication unit that performs communication 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 the configuration 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 in charge of respective communication areas, and even if a terminal which is a mobile station moves, the communication area remains within the communication area of any of the base stations. If there is, communication can be performed. Also, the terminal itself can recognize the base station area to which the terminal currently belongs, and the current position of the terminal is managed by the location registration station. In the present invention, it is assumed that camera terminals are widely spread, and there is a person who owns such a camera terminal in any base station area.
[0026]
The movement monitoring target (reporting object) in the present invention is any object that can be photographed by a camera and that can change its position over time, and may be a person, an object, an animal, a vehicle, or the like. Now, it is assumed that the monitoring target 71 is generated or found in the area of the 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. I 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 uses his or her camera terminal 10 to report to the server 50 (see FIG. 1). At this time, the user activates the emergency communication mode provided in the camera terminal by a predetermined operation such as menu selection or predetermined button instruction. As a result, a “first notification screen” as shown in, for example, FIG. 6A is displayed on the camera terminal. On this screen, a message is displayed, such as "If you take a picture of a report, you will be automatically notified to the center. There may be a confirmation message later." At this time, the camera is in a state of waiting for photographing, and when the user points the camera toward the subject and presses the shutter button, photographing is performed. When the cancel button is instructed, the emergency contact mode is canceled.
[0028]
After photographing the report, as shown in FIG. 6 (b), the photographed image is displayed on the display screen of the terminal together with a message for confirming the propriety of the report such as "Do you want to report the next image?" Is displayed. The screen information is associated with information for accessing the server. When the user designates 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 in a case where the camera terminal user voluntarily makes a report, and is distinguished from a second report which is reported by a request from the server 50 described later. The contents of the first report are a photographed image, a photographing time, base station information (identification information of a base station area in which the terminal is currently registered), and a reporter ID. In the present embodiment, the base station information forms the position information. Here, the reporter ID is reporter identification information, such as a telephone number of a camera terminal and an e-mail address, which can be used by the server side to identify the user and be used for contacting the user.
[0029]
The first notification from the terminal to the server can be made by e-mail. In this case, it is assumed that the contact e-mail address of the server 50 is stored in the terminal in advance when the application for emergency contact is installed. In this example, it is assumed that when the OK button is instructed on the screen of FIG. 6B after the activation of the emergency communication mode, the attached image file is attached to the mail and the mail is transmitted to the server. In addition to the attached photographed image, a template in which a destination, a subject, a transmission source, and a text (a prescribed message and preferably a telephone number of a terminal) are associated can be used to generate the mail.
[0030]
However, as long as the content of the first report can be transmitted to the server, any communication protocol other than e-mail may be used. For example, the server 50 may be a Web server, and after accessing the server 50 from a terminal using the http protocol, a prescribed message and a captured image may be transferred to the server 50.
[0031]
In the server 50 receiving the first notification, preferably, the person in charge checks the captured image and determines whether or not the captured image is a notification worthy of tracking. If necessary, contact the user who made the first notification to confirm the situation. It is also conceivable that the first report is sent independently from a separate camera terminal for the same report. In such a case, the number of the first reports to be notified of the emergency may be reduced to one. The accumulation of the first notification information itself may be performed a plurality of times. If the server can automatically judge such a report, there is no need for a person in charge. Instead of performing it 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 a captured image ID to at least the first report determined to be necessary for tracking, and, as the first report information, together with the base station ID, the photographing time, and the reporter ID. For example, as shown in FIG. 10A, the information is registered in a first notification information management table 81 provided in the external storage device 316. FIG. 10 is a diagram showing a configuration example of a database used in the present embodiment. The image data 83 corresponding to the captured image ID is stored in the external storage device 316 with a unique captured image ID. The “reporter ID” in FIG. 10 is the aforementioned reporter ID or information associated therewith.
[0033]
If it is determined that the report of the first report deserves the tracking, the server 50, as shown in FIG. 7, transmits the base station specified by the base station information notified by the first report (the base station B in this example). ) And adjacent base stations (in this example, base stations A, E, F, C, I, and H) perform a broadcast communication requesting at least a second report to the camera terminal. In the example of FIG. 7, the base station area with hatching is the range of the contact information. This broadcast, for the control station of the base station, for example, by using a common control channel, while transmitting an emergency contact signal to the terminal in the base station, while responding to the terminal, A screen including a prescribed message such as "Please cooperate with the second report" is prepared as shown in FIG. The screen information is associated with information for accessing the server. Terminals without a camera do not respond because they do not have a function to respond to the emergency notification signal.
[0034]
If the user indicates the No button on the screen of FIG. 8A, the cooperation is rejected. If the user instructs the Yes button, the terminal automatically accesses the server 50 and says, "If you find the next image, take a picture with the camera. There may be a confirmation message later." Such a prescribed message and the image data of the first notification are received. This example is shown in the screen of FIG. If a cancel button is instructed on this screen, cooperation is rejected, or the screen returns to the screen of FIG. When the OK button is instructed, the camera enters a shooting waiting state. When shooting is performed, a screen as shown in FIG. 8C is displayed. As in the case of FIG. 6B, the second notification information including the new captured image is transmitted to the server by the 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]
Instead of using the common control channel, the server can send an emergency message to the terminal using an e-mail attached to the terminal, instead of using the common control channel. In this case, the mail address of the user who is in the area of the contact base station is selected from the registered mail addresses of the users who cooperate with this service in advance and used.
[0036]
In the server 50 receiving the second notification information, the person in charge preferably checks the captured image to determine whether or not the captured image is the same as the tracked object in the first notification. If necessary, contact the user who made the second notification to confirm the situation. If such a determination can be made automatically by the server, the intervention of a person in charge is unnecessary. Alternatively, even if it is sufficient to verify the report history ex-post, including false reports, the intervention of a person in charge is unnecessary. The server 50 adds a unique second report number and a photographed image ID to the captured image determined to be the same as the tracked object in the first report, and assigns them to the first report number, the base station ID, and the photographed image. The information is registered in the second report information management table 82 provided in the external storage device 316 as shown in, for example, FIG. The image data 83 corresponding to the captured image ID is stored in the external storage device 316 with a unique captured image ID attached thereto, similarly to the image data of the first notification.
[0037]
After that, the server 50 performs emergency contact again according to the instruction of the person in charge. At this time, if the base station area where the tracked object is located has changed (for example, as shown in FIG. 9, if the area has moved from the base station B to the area of the base station C), the contact base station is updated. I do.
[0038]
The report of the user who has responded to the emergency report should be called the third report, but since it is substantially the same as the second report, in the present specification, the third report and thereafter will be 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 the emergency notification may be replaced with the captured image of any of the immediately preceding notifications. If the appearance of the message changes over time, this replacement allows a more current appearance to be used for emergency communication. The selection of a new image to be used for replacement may be performed automatically, or the person in charge may select a more appropriate image.
[0039]
As described above, the photographed image and the position information of the notification object whose tracking has been started by the first notification are sequentially accumulated in the server 50 together with the time information. If the tracked object is related to a dangerous substance, a crime, or the like, the authorities can use the data to quickly respond.
[0040]
A processing flow of the next server and camera terminal related to the present embodiment will be described.
[0041]
FIG. 11 is a flowchart illustrating a first notification process of the camera terminal.
[0042]
When the user of the camera terminal finds a monitoring target to be notified, as described above, the terminal shifts to the first notification mode in response to the user's first notification instruction operation (S11, Yes) (S12). . At this time, the first notification screen as described in FIG. 6A is displayed. 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), the confirmation screen as described in FIG. 6B is displayed (S15). If there is an OK instruction from the user (S16, Yes), a 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 notification from the terminal to the server is performed by e-mail, the first notification screen information in step S12 is prepared in the camera terminal and is performed off-line. On the other hand, when the first report is sent to the Web server, the first report screen can be received from the server.
[0043]
FIG. 12 is a flowchart illustrating a report information collection process executed by the server.
[0044]
When the server receives the first report (S31, Yes)), it determines whether or not it should be tracked based on the content of the report, automatically or based on an input instruction of a determination result by a person in charge. . If the result of this determination is "tracking required" (S32, Yes), the contents of the first report are registered in the first report information management table 81 (FIG. 10), and the captured image data is stored (S33). Specifically, a first report number and a photographed image ID are assigned to the first report, and the first report is registered in the first report information management table 81 together with the received base station information and photographing time information. Next, the base station of the contact to which the emergency contact is to be made is determined (S34). As described above, this applies to the base station area where the first notification is made and the adjacent base station area. However, these areas are examples of the “periphery”, and the present invention is not limited to this. The server makes an emergency contact (request for the second report) to all terminals of these base stations (S35).
[0045]
The terminal that has received the emergency notification 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 (S36, Yes) for the user to offer cooperation (S36, Yes), and sends the terminal the screen information for the second notification as shown in FIG. It is transmitted (S37). When camera shooting is performed in the terminal and an OK instruction is given on a screen as shown in FIG. 6C, information of the second notification is transmitted to the server. Upon receiving this information (S38, Yes), the server determines whether the second notification information is valid automatically or based on an input instruction of the determination result by the person in charge (S39). This step may include not only determining the validity of the second notification information itself but also processing for determining that the redundant second notification information is invalid. For example, with respect to 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 report information of the newer time and discard the second report information of the older time.
[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 photographed 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 photographing time information. If the person in charge gives an instruction to end (S41, Yes), the process returns to the first step S31. When the subsequent second report is interrupted for a predetermined time or more for the same first report, it may be automatically determined that the process is completed, and the process may return to step S31. If it is not completed, it is determined whether or not to perform emergency notification for the second report (S42). If a plurality of valid second reports are generated within a short time, it is useless to perform emergency notification for all of them, and the response on the server becomes complicated. This is to prevent it from being used as a trigger for emergency notification (second report request). This determination may be made by the person in charge, but may also be made automatically based on a time determination or the like. For example, when there are a plurality of valid second reports within a predetermined unit time, one of the processes may be used as a trigger for a further second report request. At this time, the second reports having different base station IDs may overlap. In this case, processing such as selecting the second report with the newest time, selecting the most common base station ID among the stored second reports, or compromising the two is performed.
[0047]
If it is determined that the emergency notification is required, that is, the second report request is to be made, the base station to be contacted is further determined (S43), and the emergency notification is made to all the terminals of the determined base station (S44). Otherwise, the process returns to step S31.
[0048]
FIG. 13 is a flowchart illustrating a second notification process of the terminal.
[0049]
When receiving the emergency notification from the server (S51, Yes), the terminal displays the emergency notification screen as described with reference to FIG. 8A (S52). On the other hand, if there is an input indicating that the user will cooperate (S53, Yes), the terminal requests the server for the second report screen information (S54), and as shown in FIG. 8B. The second report screen information is received from the server and displayed (S55). Next, the mode shifts to the second notification mode, and the camera shooting mode is entered (S56). Thereafter, if there is no cancellation instruction from the user (S57, No), when the shutter is turned on by the user operation (S58, Yes), a confirmation screen as shown in FIG. 8C is displayed (S59). . On the other hand, when a confirmation OK instruction is obtained from the user, the terminal makes a second notification to the server (S61). As described above, the contents are the first report number, the photographed image, the photographing time, the base station information, and the reporter ID. After the execution of the second notification, the second notification mode is released (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, the control station, and the like 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, except that 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 unit that receives a radio wave from a GPS satellite via the GPS antenna 213 to obtain latitude and longitude as current location information. In this embodiment, a GPS position detection result is used as position information reported from the terminal and managed by the server. Accordingly, although not shown, the item of “current position” of the terminal is provided in the first and second report information management tables 81 and 82 (FIG. 10). The item of “base station ID” is left in order to specify the contact information for emergency contact (the request destination of the second report). However, when requesting the second report by e-mail from the server to the terminal, the location within a predetermined radius distance from the current position is notified using the GPS detection position without using the base station ID to determine the contact information. When determining the destination area, the item of “base station ID” is unnecessary.
[0052]
In the present embodiment, by using the GPS position detection result as the position information, it is possible to more accurately track the position of the notification object.
[0053]
The preferred embodiment of the present invention has been described above, but various modifications and changes other than those mentioned above are possible.
[0054]
For example, although "emergency communication" has been described as an example, the report target is not necessarily limited to "emergency (emergency)".
[0055]
Although the second report for the first report is not distinguished from the second report for the second report and the second report further lower, the third report, the fourth report,... The report information may be distinguished and the report information of each layer may be stored in the server. In that case, for example, by including hierarchy information indicating which hierarchy the report request received by the terminal is based on in the emergency notification, and returning the hierarchy information in the notification to the server, the server The hierarchy of the notification can be identified.
[0056]
The terminal is a mobile phone terminal as an example, but may be a PHS (simple mobile phone) terminal. In the case of the 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. Also, the present invention can be applied to a wireless LAN system instead of a telephone system.
[0057]
【The invention's effect】
According to the notification information collection system of the present invention, the following remarkable effects are obtained.
[0058]
1. By effectively utilizing the mobile terminal device with a camera owned by an unspecified number of users and an existing communication network, sighting information including a captured image can be sequentially stored in a server together with shooting time information. This information can be effectively used for follow-up survey of the report.
[0059]
2. Since a camera-equipped mobile terminal device owned by an unspecified number of users is used, a relatively low-cost report information collection system can be constructed.
[0060]
