Description

  The present invention relates to an image confirmation system capable of confirming an image of a monitoring camera with a monitoring display device when an abnormality occurs, and confirming an image of the monitoring camera with a user terminal in a disaster.

  2. Description of the Related Art Conventionally, there is known a monitoring camera system in which a monitoring camera is installed in a property such as a facility or a building and its image is confirmed via a network or an abnormality is monitored at a remote monitoring center. Such a surveillance camera system is usually installed by a system installer for the purpose of monitoring an installation target, and only the system installer can handle camera images.

  On the other hand, there has been proposed a camera system that distributes video from a surveillance camera and transmits it externally and collects video information in a predetermined server when a disaster or the like occurs (see, for example, Patent Document 1). According to this camera system, it is possible to grasp the disaster situation in each place at the time of a disaster from the video of the surveillance camera.

  However, the characteristics of the image required for the monitoring purpose camera image that is usually used for private use and the damage confirmation camera image that is used for public use in the event of a disaster differ depending on the purpose.

  For example, when a supervisor checks the monitoring video at a remote monitoring center, it is necessary to check the video immediately after an abnormality occurs in the installation target for early abnormality confirmation, but the abnormality has been recovered. In later normal conditions, the need to monitor the video is reduced. On the other hand, when video is provided to an unspecified number of people who want to view the video in order to check the damaged video at the time of a disaster, the timing at which the user wants to browse varies, and any timing for each user. Therefore, it is possible that camera images will be used for a certain period after the disaster has subsided.

  In this way, in the case of surveillance video for anomaly monitoring purposes such as crime, there is a characteristic that real-time performance is required and browsing demand becomes short, while in the case of disaster video for situation confirmation purposes, immediately after the disaster However, there is a characteristic that browsing demand occurs at an arbitrary timing, and the browsing demand continues for a certain period after the disaster has stopped.

  In the conventional system, such a difference in characteristics depending on the purpose of image use is not taken into consideration.

  The collation unit 251 determines whether or not the user who inputs the operation on the operation unit 20 is a registered user. Specifically, the collation unit 251 determines whether or not the user ID information acquired from the operation unit 20 matches that registered in the storage unit 24 in advance (is collation OK). If they match, the user is authenticated as having the proper operation authority, and the operation mode of the security device 2 can be shifted by the operation performed through the operation unit 20 (by the mode setting unit 252).

  The mode setting unit 252 sets the operation mode of the security device 2 by the user's operation determined by the collation unit 251 as collation OK by the collation unit 251. As an operation mode of the security device 2, at least two types of a security set mode and a security release mode are set.

  Here, the security set mode is a mode in which when the detection signal is input from the security sensor, it is determined that the monitoring area is abnormally detected and the center device 4 is notified of the abnormality. The security release mode refers to a mode in which no abnormality is detected in the monitored area and no abnormality is reported even if a detection signal is input from the security sensor. In addition, the detection signal by a fire sensor and an emergency button is constantly monitored, and an abnormality is reported in any of the security set mode and the security release mode. For example, the user operates the operation unit 20 to set the security set mode when the security target is unmanned, and operates the operation unit 20 to set the security release mode when entering the security target.

  When the operation mode of the security device 2 is set, the mode setting unit 252 transmits a mode setting signal indicating the set operation mode from the communication unit 21 to the recording processing server 5.

  When the abnormality determination unit 253 receives the detection signal from the sensor, the abnormality determination unit 253 determines whether or not there is an abnormality in comparison with the current mode and the sensor information in the storage unit 24. In addition, the abnormality determination unit 253 determines that it is abnormal when a detection signal is received from any of the various sensors when the security set mode is set, and when the security release mode is set, When a detection signal is received from any of the buttons, it is determined that there is an abnormality. If the abnormality determination unit 253 determines that there is an abnormality, the abnormality determination unit 253 transmits an abnormality signal indicating the abnormality to the recording processing server 5 from the communication unit 21. The abnormality signal includes the identification number of the security device 2, the ID number of the sensor that detected the abnormality, the type of the sensor, and the information on the installation position thereof. If the abnormality determination unit 253 determines that the event has been recovered at the transmission source of the detection signal determined to be abnormal, the abnormality determination unit 253 transmits a recovery signal to the recording processing server 5.

<Center device>
FIG. 4 is a block diagram showing the configuration of the center device 4. As shown in FIG. 4, the center device 4 includes a recording processing server 5 and a WEB server 6. The recording processing server 5 includes an information storage unit 50, a disaster determination unit 51, an abnormality detection unit 52, an image storage unit 53, an image data conversion unit 54, a monitor display control unit 55, and a user display control unit 56.

  The information storage unit 50 manages, as the installation area information where the monitoring camera 1 is installed, the information of the monitoring area such as the address, the area, and a major nearby facility (landmark), the camera number, and the identification number of the security device 2 Information is stored in advance. The management information stores outdoor flag information for identifying whether the installation location is indoor or outdoor as information registered at the time of installation for each surveillance camera 1. If the outdoor flag is ON, it indicates that it is installed outdoors. The management information is managed as table information having various flags, and is updated as needed depending on the operation mode setting of the security device 2, the presence / absence of an abnormality, the presence / absence of a disaster, and the like.

  Moreover, the information storage part 50 has memorize | stored the operation mode currently set for every security apparatus 2 in management information. When the recording processing server 5 receives the mode setting signal from the security device 2, the operation mode is recorded as current mode information in association with the corresponding security device 2 in the management information. Further, the information storage unit 50 stores an ID and a password as user verification information corresponding to each monitoring area.

  The disaster determination unit 51 receives disaster information including information on a disaster occurrence area from the information providing source device (external device). For example, when the disaster determination unit 51 receives disaster information from an information distribution device of a disaster information distribution provider such as a public institution that is an information providing source device, the disaster determination unit 51 stores this along with the reception time. The disaster information is, for example, an earthquake early warning, but other information related to various disasters such as information on tsunami prediction, typhoon warning, and information on fire may be distributed as disaster information.

  The disaster determination unit 51 stores in advance parameters (disaster intensity) indicating the intensity of the disaster such as seismic intensity, precipitation, and wind speed as a disaster intensity threshold, and the disaster information to be dealt with when disaster information exceeding the disaster intensity threshold is received. Determine occurrence. When it is determined that a disaster has occurred, the disaster determination unit 51 determines whether any of the monitoring areas are included in the disaster occurrence area. If included, the monitoring camera 1 and the security device corresponding to the monitoring area are included. The disaster flag is turned on for 2 (the disaster flag is enabled on the management information table). The disaster determination unit 51 turns off the disaster flag when a predetermined period has elapsed since the disaster flag was turned on. The predetermined period is a period set in advance according to the disaster intensity of the disaster information. For example, when the disaster information is an earthquake early warning, when the seismic intensity is 3, the predetermined period is set to 1 day, and when the seismic intensity is 6, the predetermined period is set to 1 week.

  The abnormality detection unit 52 detects an abnormality in the monitoring area based on information (abnormal signal) input from the monitoring camera 1 or the security device 2. When an abnormal signal is input from the security device 2, the abnormal flag of the corresponding monitoring area is turned ON in the management information (the abnormal flag is enabled on the management information table). Further, when the amount of change is greater than or equal to a predetermined amount based on the image data input from the monitoring camera 1, it may be determined as abnormal. Moreover, the abnormality detection part 52 determines abnormality recovery of a monitoring area based on the information (restoration signal) input from the monitoring camera 1 or the security device 2, and turns OFF the abnormality flag of the corresponding monitoring area.

  The image storage unit 53 stores image data acquired from the monitoring camera 1 and a data table for managing the image data. The image data recording area is divided in advance for each camera or each monitoring area, and the image data of the corresponding monitoring camera 1 is recorded by receiving the image data.

  The data table is information for identifying the recorded image data, and includes the recording ID of the image data and additional information of the image data (camera ID, device type of the monitoring camera 1, device type of the lens used, shooting conditions) , The shooting date and time) is recorded in association with the address information in which the image data is recorded.

  The image data conversion unit 54 down-converts the image data acquired from the surveillance camera 1 to a preset definition and converts it to low-definition image data. Specifically, the image data conversion unit 54 performs down-conversion if the image data received from the monitoring camera 1 has a higher image quality than a preset resolution (for example, VGA resolution), and low-definition image data with VGA resolution. Convert to The converted low-definition image data is recorded in the image storage unit 53 in association with the basic image data before conversion (image data received from the monitoring camera 1).

  Here, an example of reducing the resolution as the content of down-conversion has been described, but the scope of the present invention is not limited to this. The image data converter 54 may reduce the definition by decreasing the frame rate, increasing the compression rate, or a combination thereof.

  Here, an example has been described in which the image data conversion unit 54 performs down-conversion when acquiring image data and stores low-definition image data in advance, but the scope of the present invention is not limited to this. When the image data is output from the user display control unit 56, the image data conversion unit 54 may perform down-conversion and conversion to low-definition image data.

  Furthermore, when the disaster flag is already ON for the monitoring camera 1 that has acquired the image data, the number of disaster occurrence areas determined by the disaster determination unit 51 (the width or the number of included areas) The degree (definition) of down-conversion may be varied. For example, the definition decreases as the number of disaster occurrence areas included in the disaster information of the disaster increases. For example, when the disaster occurrence area is “all areas of Tokyo”, downsizing is performed as compared with the case of “only Chiyoda-ku, Tokyo”. As a result, the data size of the image data can be reduced as the number of potential browsing consumers increases.

  The monitoring display control unit 55 outputs the image data received from the monitoring camera 1 to the monitoring display device 7 together with the monitoring target information and abnormality information. When the monitor display control unit 55 receives the image data, if the abnormality flag of the corresponding monitoring area is ON in the management information, the monitoring display control unit 55 outputs this to the monitoring display device 7. Further, when a request for image data is received from the monitoring display device 7, if the abnormality flag of the monitoring area corresponding to the requested image data is ON, this image data is read from the image storage unit 53 and monitored and displayed. Output to the device 7.

  In this way, the image data provided to the monitor is image data that maintains the original definition, so that the cause can be grasped from the image at the time of abnormality, and the evidence of the image is enhanced. Yes.

  When the WEB server 6 receives a browsing request from the user, the user display control unit 56 reads out low-definition image data for the image data corresponding to the requested area and outputs it to the WEB server 6 together with the area information. And transmitted to the user terminal 9. The regional information that is output at this time is information that indicates a regional area that is wide to some extent, such as classification of municipalities.

  When receiving the input of area information from the user terminal 9 as the browsing request signal, the user display control unit 56 extracts a monitoring area corresponding to the area information from the management information. The user display control unit 56 performs control so that the user can view the image only for the monitoring camera 1 in which the disaster flag of the corresponding monitoring area in the management information is ON and the outdoor flag is ON. Therefore, when the user display control unit 56 receives a browsing request from the user, if the disaster flag of the corresponding monitoring area in the management information is ON, the monitoring camera 1 whose corresponding outdoor flag is ON. The low-definition image data that is the most recent recording unit is read and output to the WEB server 6. If the disaster flag is OFF, or if all the corresponding surveillance cameras 1 are the outdoor flag OFF, the image data is not read and an error message is returned.

  As described above, the image data provided to the user can use data having a smaller data size than the original image data. As a result, it is possible to provide images continuously to users by reducing the possibility of processing delays and system outages even when access is concentrated during a disaster in a highly peaked disaster image providing service. It becomes.

  As an exception to this processing, the user display control unit 56 stores the information specifying the monitoring area and the ID / password as an authentication signal from the user via the WEB server 6 and stores them in the information storage unit 50. If the collation information is collated and it is determined that the collation for the designated monitoring area or the surveillance camera 1 is OK, image browsing is permitted regardless of the disaster flag and the outdoor flag. Particularly in this case, basic image data that has not been down-converted (image data received from the monitoring camera 1) may be output to the user terminal 9 instead of low-definition image data. Thereby, the legitimate user who is the installation target of the monitoring camera 1 and becomes a specific user can check the image of his / her management range via the WEB server 6.

  The WEB server 6 includes an access receiving unit 60. The access receiving unit 60 has a function of receiving access from the user terminal 9.

  The user accesses the URL of the portal site set in the access reception unit 60 of the WEB server 6 from the user terminal 9 as a client device such as a personal computer or a smartphone by using a dedicated application or a WEB browser. It is possible to designate and refer to the image data of the surveillance camera 1 that is disclosed so as to be viewable.

  In addition, the user can refer to the image data of the monitoring camera 1 in the monitoring area corresponding to the user by inputting collation information such as a preset ID and password.

  The WEB server 6 accepts access from the user terminal 9 and outputs image data. When the user accesses the WEB server 6, the WEB page of the portal site on which the input unit for specifying the area information that the user desires to view the image data and the input unit for inputting the user verification information is installed. It transmits to the user terminal 9. The user designates regional information desired to be browsed on the WEB page, and transmits a browse request signal for requesting image data to the WEB server 6. For example, it is possible to designate the area information up to the division of the city / town / village name or the division of the town area. In addition, it may be possible to designate neighboring main facilities (landmarks) as the regional information. Alternatively, a user who has previously obtained collation information from the monitoring center inputs his / her collation information and transmits an authentication signal requesting authentication to the WEB server 6.

  The WEB server 6 outputs information input from the user terminal 9 to the user display control unit 56. When the user display control unit 56 determines that the corresponding image data can be referred to, when providing the image data to the user terminal 9, a known method such as file transfer or streaming may be employed. The corresponding image data includes the image data of the outdoor monitoring camera 1 whose disaster flag is temporarily turned ON due to the occurrence of a disaster, and the monitoring camera 1 (browsing is permitted in advance corresponding to the collation information) For example, a user to be installed).

<Monitoring display device>
The monitoring display device 7 is composed of one or a plurality of computers and its operation unit and display unit, and displays various information such as image data received from the recording processing server 5 and the name and address of the monitoring area on the display unit, The monitoring staff constantly monitors the monitoring target. The monitoring display device 7 can access the management information of the recording processing server 5 as a database storing information of the monitoring target and the security device 2 installed there.

  On the display unit of the monitoring display device 7, information on the monitoring target to be dealt with based on the abnormality from the security device 2, information on the abnormality, and image data of the monitoring camera 1 installed on the monitoring target are displayed. For example, information specifying the property to be installed such as the name and address of the monitoring area is displayed. If the monitor sees such a display and determines that an abnormality has occurred in the monitoring area, the monitor takes necessary measures such as a coping instruction of the coping person to the monitoring target. For example, the monitor checks the received image data on the display unit, and if the occurrence of a fire such as flame or smoke is recognized, the monitor gives instructions to handle the monitoring target and makes a 119 report.

  The operation of the image confirmation system configured as described above will be described with reference to the drawings.

  In the image confirmation system according to the embodiment of the present invention, the abnormality flag control as shown in FIG. 5 is executed. The abnormality flag control is executed by the recording processing server 5 (mainly the abnormality detection unit 52) of the center device 4.

  In the abnormality flag control, first, it is determined whether or not an abnormality signal has been received from the monitoring camera 1 or the security device 2 (S100). When an abnormality signal is received, it is determined that abnormality has been detected by the abnormality detection unit 52 (S101), and the abnormality flag of the camera in the monitoring area is set to ON (S102). On the other hand, if no abnormal signal is received, a determination is made as to whether the monitored area is abnormally restored (S103). For example, when a recovery signal is received from the monitoring camera 1 or the security device 2, it is determined that the abnormality in the monitoring area has been recovered, and the abnormality flag is set to OFF (S104).

  In the image confirmation system according to the embodiment of the present invention, when the image of the monitoring camera 1 is confirmed by the monitoring display device 7 at the time of abnormality, monitoring display control as shown in FIG. 6 is executed. The monitoring display control is executed by the recording processing server 5 (mainly the monitoring display control unit 55) of the center device 4.

  The monitoring display control is executed when an abnormality is detected in the monitoring area. Therefore, first, the recording processing server 5 determines whether or not an abnormality is detected in the monitoring area (S1). When an abnormality is detected, image data of the monitoring area (monitoring area where the abnormality is detected) is provided to the monitor display device 7 so that the monitor can select it (S2). When the monitor selects the image data on the monitor display device 7 (for example, by clicking the image), the recording processing server 5 reads the selected image data (S3), and the image data and the installation target ( Information specifying the monitoring area is output to the monitoring display device 7 (S4). Until the abnormality is recovered, the output of the image data selected in this way is repeated. Thereafter, when the abnormality in the monitoring area is recovered (S5), the output of the image data is prohibited (S6), and the process is terminated.

  In the image confirmation system according to the embodiment of the present invention, disaster flag control as shown in FIG. 7 is executed. The disaster flag control is executed by the recording processing server 5 (mainly the disaster determination unit 51) of the center device 4.

  In the disaster flag control, first, it is determined whether disaster information has been received from the information providing source device (external device) (S110). The disaster information includes at least disaster intensity information and disaster occurrence area information. When disaster information is received, the disaster determination unit 51 determines whether or not the disaster intensity indicated by the disaster information is greater than or equal to the disaster intensity threshold (S111). If the disaster intensity is greater than or equal to the disaster intensity threshold, it is determined that a disaster has occurred (S112). If it is determined that a disaster has occurred, the disaster flag of the monitoring camera in the surveillance area included in the disaster occurrence area is set to ON (S113), and a predetermined period according to the disaster intensity (for example, the disaster information is an emergency earthquake warning) 1 day for seismic intensity 3 and 1 week for seismic intensity 6) (S114).

  On the other hand, when disaster information is not received from the information providing source device (external device), it is determined whether or not the predetermined period set in step 114 has elapsed (S115). If the predetermined period has elapsed, the disaster flag is set to OFF (S116).

  In the image confirmation system according to the embodiment of the present invention, when the image of the monitoring camera 1 is confirmed at the user terminal 9 at the time of a disaster, the user display control as shown in FIG. . The user display control is executed by the recording processing server 5 (mainly the user display control unit 56) of the center device 4.

  The user display control is executed when there is a browsing request from the user terminal 9 via the WEB server 6. When there is a browsing request from the user terminal 9 (S10), it is first determined whether or not the user is a specific user (S11). If the user is not a specific user (that is, if the user is a general user who does not input unique verification information), it is determined whether or not the disaster flag of the monitoring area requested to be viewed is ON (S12). When the disaster flag is ON, it is determined whether there is an image of the monitoring camera 1 that can be browsed (S13). The browsing monitoring camera 1 is a monitoring camera 1 with a disaster flag ON and an outdoor flag ON. The disaster flag is turned ON when the monitoring area is included in the disaster occurrence area, and is turned OFF when a predetermined period has elapsed since turning ON. The predetermined period is set in advance according to the disaster intensity of the disaster information. For example, when the disaster information is an earthquake early warning, when the seismic intensity is 3, the predetermined period is set to 1 day, and when the seismic intensity is 6, the predetermined period is set to 1 week.

  When there is an image of the monitoring camera 1 that can be browsed, the low-definition image of the monitoring camera 1 is read (S14), and the low-definition image and the area information of the monitoring camera 1 are output to the user terminal 9 ( S15). In particular, at this time, the classification of the municipality name or the classification of the town area is output as the regional information. Thereafter, it is determined whether or not the disaster flag is turned off (S16). When the disaster flag is turned off, the output of the low-definition image is prohibited (S17), and the process is terminated. Even if the disaster flag remains ON, if an input to end browsing is received from the user terminal 9 (S18), the process ends.

  When the user is a specific user, the authentication signal input from the WEB server 6 is compared with the verification information to identify the monitoring area corresponding to the specific user (S19), and the image data of the monitoring area Is provided to the user terminal 9 so that the user can select it (S20). In this case, even if the monitoring area is outside the disaster occurrence area, the image data of the monitoring area is provided so as to be selectable. When the user selects image data at the user terminal 9 (for example, by clicking on the image), the recording processing server 5 reads out the selected image (S21), and the image data and the installation target (monitoring). Information (area name and address, etc.) specifying the area is output to the user terminal 9 (S22). Thereafter, when an input for browsing termination is received from the user terminal 9 (S23), the process is terminated.

  In such an image confirmation system of the present embodiment, the image data received from the monitoring camera 1 is transmitted from the center device 4 to the monitoring display device 7 and the user terminal 9. In the monitoring center for crime monitoring purposes, where observers are always stationed to monitor the occurrence of anomalies, and in the portal site for disaster situation confirmation purposes, where many users check images at their own timing in the event of a disaster, etc. The characteristics are different. In the present invention, the viewing period is different for the purpose of monitoring the abnormality and the purpose of confirming the disaster status, and the image data of the monitoring camera 1 installed in the disaster occurrence area is set during the confirmation period set in advance according to the disaster scale. It can be confirmed from the user terminal 9. Thereby, while being able to respond to the short-term browsing demand from the monitoring display device 7 at the time of abnormality, it is possible to cope with the browsing demand that continues for a certain period from the user terminal 9 even after the disaster has stopped.

  Further, in the present embodiment, when an installation target abnormality is detected, the image data of the monitoring camera 1 can be confirmed from the monitoring display device 7 until the abnormality is recovered. Thereby, it is possible to cope with a short-term browsing demand from the monitor display device 7 at the time of abnormality.

  In the present embodiment, the image data received from the monitoring camera 1 corresponding to the specific user is transmitted to the user terminal 9 of the specific user even outside the disaster occurrence area. . This allows a specific user (a legitimate user to install a surveillance camera) to check the surveillance camera image (high-definition image) of his / her management range at any time on a portal site, etc. It is possible to ensure privacy by preventing the restored normal image from being inadvertently referred to.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified according to the purpose within the scope of the claims. is there.

  As described above, the image confirmation system according to the present invention can respond to a short-term browsing demand from a monitoring center or the like in the event of an abnormality, and can also respond to a browsing demand that continues for a certain period of time after a disaster.
