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.

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. That is, in the security set mode, a notification is made when the presence of a person is detected in the security target. In the security release mode, no notification is made even if the presence of a person is detected in the security target. 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 the present embodiment, an abnormality is a state that is detected when the monitoring area to be guarded or its user is not normal, and is determined when the maintenance of the monitoring area or its user can be impaired. It is. Specifically, the abnormality determination unit 253 determines that an abnormality is detected when a detection signal is received from any of the various sensors when the security set mode is set, and the disaster prevention unit 253 performs disaster prevention when the security release mode is set. When a detection signal is received from either the sensor or the emergency button, it is determined as abnormal. 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 so as to notify the abnormality. 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.

  The manned / unmanned determination unit 254 determines whether there is a user as a security target and transmits the determination result to the recording processing server 5. It is possible to use a known technique to determine whether a user is present in the security target (manned / unmanned determination), for example, using a sensor installed in the security target, an access control system, or the like. Can do. When using the entrance / exit management system, it is possible to determine whether the security target is manned or unmanned based on the difference between the visitor's history and the exit's history. The manned / unmanned determination can also be performed by performing image processing (person detection processing or the like) on the camera image of the surveillance camera 1 installed in the security target. In the present embodiment, when the security setting mode is set by the mode setting unit 252, it is determined that there is no user (unmanned), and when the security release mode is set, it is determined that the user exists (manned). An example will be described.

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 value. 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 compares the image data acquired from the surveillance camera 1 with the past image data (reference image data), and extracts a variation area composed of variation pixels whose luminance value variation is equal to or greater than a predetermined value. To do. There are various methods for extracting the fluctuating region, such as an inter-frame difference method based on a difference from the immediately preceding image data and a background difference method based on a difference from image data at a reference time acquired in advance for each camera (not detailed here). ) Is available. For example, when the background difference method is used, the image data at the base time point is stored in advance in the memory area of the image data conversion unit 54 as a background image (reference image) for each monitoring camera 1.

  The image data conversion unit 54 performs a blurring process for reducing the color of the extracted fluctuation region, for example, to reduce the color to a monochrome binary video. Then, the blurred variation area is synthesized with the original image data, thereby generating unclear image data in which only the variation area is unclear. The unclear 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).

  In the case of a monochrome binary video, since the silhouette of the object to be photographed is known, it is possible to determine the approximate situation related to the object to be photographed, but privacy can be protected because it is not a detailed image of the object to be photographed. Note that the process of blurring the fluctuation area is not limited to this, and the sampling density of the fluctuation area may be coarsened to form a low-resolution image in a substantially mosaic shape, or the fluctuation area may be masked to a single color. . In addition, the process of blurring the fluctuation area may be a process of converting the image data of the fluctuation area into a grayscale edge image. Even with a gray-scale edge image, privacy can be protected because the silhouette of the object's edge region is clear but not a detailed image. The blurring process is not limited to the above-described processes as long as the extracted fluctuation region is blurred, and may be realized by other processing methods. Further, each of the above-described processes, that is, a color reduction process, a resolution reduction process, a mask process for a predetermined area, a light / dark edge imaging process, or a combination of all processes may be used.

  Further, here, an example has been described in which blurring processing is performed at the time of obtaining image data and blurry image data is stored, but the scope of the present invention is not limited to this. For example, when the image data is output from the user display control unit 56, the blurring process may be performed and the conversion process to the blurred image data may be performed.

  When the monitoring display control unit 55 receives an abnormal signal from the security target side device (the monitoring camera 1 or the security device 2), the monitoring display information and the abnormality information together with the image data received from the monitoring camera 1 (i.e. The image data that has not been subjected to the blurring process is output to the monitor display device 7. 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 unclear image data for the image data corresponding to the requested area, and outputs it to the WEB server 6 together with the area information. To the user terminal 9. The regional information to be output at this time is information indicating a regional area that is wide to some extent, such as classification of municipalities.

  In this case, the user display control unit 56 transmits only the image data of the monitoring camera 1 installed in the security target in which the security device 2 is set to the security set mode to the user terminal 9. That is, the image data of the monitoring camera 1 installed in the security target in which the security device 2 is set to the security release mode is not transmitted to the user terminal 9.

  Moreover, not only when it is set to the security set mode, the user display control unit 56 is installed in the security target determined that the user is not present (unmanned) by the manned / unmanned determination unit 254. Only the image data of the monitoring camera 1 may be transmitted to the user terminal 9. That is, the image data of the monitoring camera 1 installed on the security target determined that the user exists (is manned) by the manned / unmanned determination unit 254 is not transmitted to the user terminal 9.

  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 unclear image data which is the latest recording unit is read out 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, as the image data provided to the user, it is possible to use the original image data having a smaller data size in which the amount of image information is reduced. 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 (image data received from the monitoring camera 1) that has not been subjected to unclear processing may be output to the user terminal 9 instead of unclear 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, when an 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. 5 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, when the image of the monitoring camera 1 is confirmed at the user terminal 9 at the time of a disaster or the like, the user display control as shown in FIG. Is done. 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 has not entered 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 surveillance camera 1 that can be viewed is the surveillance camera 1 installed in the security target whose security device is set in the security set mode or the surveillance camera 1 installed in the security target determined that there is no user. Thus, the surveillance camera 1 has the disaster flag ON and the outdoor flag ON.

  When there is an image of the monitoring camera 1 that can be browsed, the unclear image of the monitoring camera 1 is read (S14), and the unclear 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 or the classification of the town 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 unclear images 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). 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.

  According to such an image confirmation system of the present embodiment, image data of the monitoring camera 1 is transmitted to the monitoring display device 7 regardless of whether or not the security device 2 is set in the security set mode. Only when the security device 2 is set to the security set mode, the image data of the surveillance camera 1 installed on the security target is transmitted to the user terminal 9. Thereby, the camera image can be confirmed by the center device 4 regardless of the operation mode of the security device 2 at the time of abnormality, and the camera image can be viewed on the portal site or the like only when the security set mode is set at the time of a disaster. In this way, it is possible to consider the privacy of a person who is within the imaging range for an image provided to an unspecified number of people at the time of a disaster, etc., without degrading the function of confirming facts at the time of abnormality.

  Furthermore, according to the image confirmation system of the present embodiment, image data of the monitoring camera 1 is transmitted to the monitor display device 7 regardless of whether or not a user exists as a security target, and the user terminal 9, image data of the monitoring camera 1 installed in the security target is transmitted only when the user is not present in the security target. Accordingly, the camera image can be confirmed by the center device 4 regardless of whether the security target is manned or unmanned at the time of an abnormality, and the camera image can be viewed on a portal site or the like only when the security target is unattended at the time of a disaster. Also by this, it is possible to consider the privacy of a person who is in the imaging range for an image provided to an unspecified number of people at the time of a disaster or the like without degrading the function of confirming facts at the time of abnormality.

  Further, in the present embodiment, the security device 2 set in the security set mode detects the entry of a person into the security target, and in the event of an abnormality, the security target side device (the monitoring camera 1 or the security device 2) changes the center device. When the notification signal is transmitted to 4 and the center device 4 receives the notification signal, the image data is transmitted from the center device 4 to the image display device 7, and the camera image at the time of abnormality can be confirmed. Further, in the event of an abnormality such as a disaster prevention sensor or emergency button installed on the security target, regardless of the operation mode of the security device 2, the security target side device (the monitoring camera 1 or the security device 2) transfers to the center device 4. When the notification signal is transmitted and the center device 4 receives the notification signal, the image data is transmitted from the center device 4 to the image display device 7, and the camera image can be confirmed.

  In the present embodiment, when a disaster occurs, it is determined whether the monitoring camera 1 is installed in the disaster occurrence area based on the installation area information where the monitoring camera 1 is installed and the information on the disaster occurrence area. Is done. Then, only for the monitoring camera 1 installed in the disaster occurrence area, image data is transmitted to the user terminal 9 in response to a request signal from the user terminal 9. In this way, the video delivered to the user at the time of a disaster is limited to only the cameras related to the disaster.

  Moreover, in this Embodiment, about the image data received from the monitoring camera 1 corresponding to a specific user, even if the corresponding security device 2 is in a security release mode, an image is displayed on the user terminal 1 of the specific user. Data is sent. As a result, the specific user (a legitimate user to which the monitoring camera 1 is installed) can check the image of the monitoring camera 1 in his / her management range on a portal site or the like.

  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 consider the privacy of an image provided to an unspecified number of people at the time of a disaster without degrading the function of fact confirmation at the time of abnormality. It has an effect and is useful for an image monitoring service that combines abnormality monitoring of facilities and buildings and confirmation of damage status at the time of disaster.
