Description

Security support system, security support method, and recording medium

[0001] The present disclosure relates to a security support system, a security support method, and a recording medium.

[0002] Patent Document 1 discloses an example of an anomaly reporting system that can prevent security entities from being called out due to false alarms from fire sensors, intrusion sensors, and surveillance camera anomaly detectors installed in buildings such as houses, bookstores, factories, warehouses, and parking lots. This document describes that this anomaly reporting system uses a building device that utilizes a personal computer in the facility to be guarded to make a judgment. If it determines that a report is necessary, it transmits an image of the abnormal situation to a terminal device such as a mobile phone managed by a manager. The manager refers to the received image, determines whether a final report is necessary, and then transmits the image to a security entity such as a security company to request a call for response.

[0003] Patent Document 2 discloses an example of a personal security system that uses a mobile terminal. This security system includes a function for selecting the nearest security terminal based on location information received from the mobile terminal, and a function for outputting a map showing the location information received from the mobile terminal and an image from the selected security terminal.

[0013] First, an overview of one embodiment of the present disclosure will be described with reference to the drawings. Note that the reference numerals in this overview are added to each element for convenience as an example to facilitate understanding, and are not intended to limit the present disclosure to the illustrated form. Furthermore, connecting lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows are used to schematically indicate the flow of main signals (data) and do not exclude bidirectionality. A program is executed via a computer device, which includes, for example, a processor, a storage device, an input device, a communication interface, and, if necessary, a display device. Furthermore, this computer device is configured to be able to communicate with internal or external devices (including computers) via the communication interface, whether wired or wireless. Furthermore, ports or interfaces are present at the input / output connection points of each block in the drawings, but are not shown.

[0014] In one embodiment, the present disclosure can be realized in a security support system 100 including a receiving means 101, an acquiring means 102, and a transmitting means 103, as shown in FIG.

[0015] The receiving means 101 receives an abnormality report from the security system 300 of the facility TF that has been set as a security target. As the security system 300, a system provided by a private security company, a building material manufacturer, or the like, which has a function of reporting to a predetermined terminal or the like when an abnormality is detected, can be used.

[0016] The acquisition unit 102 selects a camera 400 located on the road RD closest to the facility TF and acquires images captured by the camera 400. The acquisition unit 102 may select the camera 400 based on the location of the facility TF, select a camera 400 that is pre-associated with the facility TF, or select a camera 400 that is pre-associated with the facility TF. Furthermore, the acquisition unit 102 may acquire images captured by the selected camera 400 without directly requesting the camera 400 to transmit the images. For example, if the camera 400 transmits images to a predetermined destination (e.g., a control center or a live camera image public server), the acquisition unit 102 may acquire the images of the selected camera 400 from the destination. The nearest road RD is not limited to a road adjacent to the facility TF. It may also include a road adjacent to the adjacent road. Furthermore, the nearest road RD may be an area adjacent to the facility TF (e.g., a parking lot) rather than a road.

[0017] The transmitting means 103 transmits the acquired image to a predetermined terminal 200. This terminal 200 may be, for example, a control terminal of a security company, or a mobile terminal or an in-vehicle terminal of a security company employee that has been set up in advance.

[0018] 2 is a flowchart showing a security support method used in the security support system 100. As shown in FIG. 2, when the security support system 100 configured as described above receives an abnormality report from the security system 300 (step S001), it selects a camera 400 located on the road closest to the facility TF. Furthermore, the security support system 100 acquires an image captured by the selected camera 400 (step S002). The security support system 100 then transmits the acquired image to a predetermined terminal 200 (step S003).

[0019] FIG. 3 is a diagram for explaining the operation of this embodiment. As shown in FIG. 3, when an abnormality occurs in a facility TF that has been set as a security target, the security system 300 transmits an abnormality notification. When the security guard support system 100 receives the abnormality notification, it selects the nearest camera 400 and acquires an image. The security guard support system 100 then transmits the acquired image to the terminal 200. Note that the images acquired by the security guard support system 100 may be images taken by a single camera 400 as shown in FIG. 3, or may be images taken by multiple cameras 400. Furthermore, the images acquired by the security guard support system 100 may be sequential images or videos.

[0020] 3, it is also possible that the suspicious person SU who has entered the facility TF is captured in the image captured by the camera 400, but the suspicious person SU is not captured in the image acquired from the camera 400. Even in such a case, by transmitting the image to the terminal 200, it is possible to allow a security control officer or the like to consider the possibility that the suspicious person SU is hiding within the facility TF or has escaped using another route.

[0021] According to the security support system 100 that operates as described above, it becomes possible to easily grasp the situation around the facility TF that has been set as a security target.

[0022] [First Embodiment] Next, a first embodiment in which a search function for suspicious persons, suspicious vehicles, etc. is added to a security support system will be described in detail with reference to the drawings. FIG. 4 is a block diagram showing the configuration of a security support system 100a according to the first embodiment of the present disclosure. Referring to FIG. 4, the security support system 100a includes a receiving unit 101, an acquiring unit 102, a transmitting unit 103, and a camera location storage unit 104. In this embodiment, the camera 400 is a camera installed at a road intersection or the like, and the facility TF to be guarded is described as being located in a corner of the area where the camera 400 is installed at a major intersection.

[0023] When the receiving means 101 receives an abnormality notification from the security system 300 of the facility TF, it transmits the location information of the facility TF contained in the abnormality notification to the acquiring means 102 and instructs it to start image acquisition operation.

[0024] The acquisition means 102 selects a camera 400 that is likely to capture an image of a person or vehicle visiting the facility TF, and acquires an image captured by the camera 400. Specifically, the acquisition means 102 selects the camera 400 based on the location information of the facility TF received from the reception means 101 and the camera layout information (the positions and orientations of the cameras arranged around the facility TF) stored in the camera layout storage means 104. As an example of a method for selecting a camera 400 that is likely to capture an image of a person or vehicle visiting the facility TF, a method of selecting one or more cameras facing in the direction of the facility TF can be adopted.

[0025] Furthermore, the acquisition means 102 selects images that show people or vehicles from the acquired images and sends them to the transmission means. In this way, the security support system 100a is provided with a function for searching for suspicious people or suspicious vehicles.

[0026] The transmission means 103 transmits the series of images acquired by the acquisition means 102 to the terminal 200a of a security officer at the facility TF. In this embodiment, the transmission means 103 uses a mobile communication network or road-to-vehicle communication to transmit the images to the terminal 200a of a security officer heading towards the facility TF or to the terminal 200a of a predetermined vehicle (e.g., a patrol car or a security car) patrolling near the facility TF.

[0027] The camera location storage means 104 stores camera location information used by the acquisition means 102 to select a camera 400. FIG. 5 is a diagram illustrating an example of camera location information. As shown in the lower part of FIG. 5, intersections 011 to 022 exist, and cameras C001 to C004 are located at intersections 011 and 021. The upper part of FIG. 5 shows camera location information for cameras C001 to C003. For example, camera C001 is installed at intersection 011 and faces southwest. Based on this information, the acquisition means 102 selects a camera 400 that is likely to capture a person or vehicle visiting facility TF. Note that the information on adjacent intersections indicates information on adjacent intersections that should be referenced when the person or vehicle in the image is moving or the image is small. For example, if the image of a person or vehicle on the east side of intersection 011 in the image captured by camera C002 is small, the acquisition means 102 can add the camera installed at intersection 021, which is an adjacent intersection, to the selection candidates. In the example of Figure 5, the locations of the cameras 400 located at intersections are stored, but cameras 400 located at locations other than intersections may also be stored in the camera location storage means 104 and added to the selection targets of the acquisition means 102.

[0028] Next, the operation of this embodiment will be described in detail with reference to the drawings. Fig. 6 is a flowchart showing the operation of the security support system 100a according to the first embodiment of the present disclosure. Referring to Fig. 6, when the security support system 100a receives an abnormality report from the security system 300 of the facility TF (step S101), it selects one or more cameras 400 at the intersections closest to the facility TF and acquires images captured by the cameras 400 (step S102).

[0029] Next, the security support system 100a selects an image that shows a person or a vehicle from the acquired images (step S103). If there are no images that show a person or a vehicle, or if you want to confirm that there are no people or vehicles, you can skip this processing step and select the image acquired in step S102.

[0030] Next, the security support system 100a selects the terminal 200a to which the image is to be transmitted (step S110). Specifically, the security support system 100a selects the terminal 200a of the security officer heading to the facility TF.

[0031] Finally, the security support system 100a transmits the image selected in step S103 to the selected terminal 200a (step S111).

[0032] According to the security support system 100a that operates as described above, it is possible to search for people and vehicles around the facility TF photographed by a camera at the nearest intersection to the facility TF, and to notify their presence to the terminal 200a of a security officer heading towards the facility TF.

[0033] Furthermore, security personnel who receive such images can contact relevant agencies such as the police and prepare equipment while on their way to facility TF. For example, security personnel can provide relevant agencies such as the police with information about people and vehicles captured in the images. Even if no people or vehicles are captured in the received images, security personnel can consider the possibility that a suspicious person or vehicle is hiding, that the person or vehicle has escaped using another route, or that the security system 300 is malfunctioning.

[0034] [Second Embodiment] Next, a second embodiment in which a tracking function for suspicious persons, suspicious vehicles, etc. is added to a security guard support system will be described in detail with reference to the drawings. Fig. 7 is a block diagram showing the configuration of a security guard support system 100b according to the second embodiment of the present disclosure. The difference from the first embodiment shown in Fig. 4 is that a tracking means 1021 is added to the acquisition means 102b of the security guard support system 100b. Since the other configurations and operations are the same as those of the first embodiment, a description thereof will be omitted and the following description will focus on the differences.

[0035] The tracking means 1021 tracks people and vehicles by estimating the direction of travel from the orientation and posture of people and vehicles captured in the images acquired by the acquisition means 102b and selecting a camera that can capture the situation in that direction of travel.

[0036] The acquisition unit 102 b repeats the process of acquiring images taken by the camera 400 selected by the tracking unit 1021 and passing them to the tracking unit 1021 for a certain period of time.

[0037] 8 is a flowchart showing the operation of the security support system 100b according to the second embodiment of the present disclosure. The difference from the first embodiment shown in FIG. 6 is that the security support system 100b is configured to track people and vehicles by predicting their destinations in the images of steps S104 and S105 and acquiring images from the cameras 400 at their destinations, repeating this process a predetermined number of times.

[0038] FIG. 9 is a diagram specifically illustrating the operation of the security support system 100b of the present disclosure. For example, suppose a suspicious individual intrudes into a facility TF to be guarded, exits the facility TF to the east, turns left at intersection 012, heads north, turns right at intersection 011, heads east, and then escapes along a route that goes straight through intersection 021, as shown by the dashed line in FIG. 9 . In this case, the security support system 100b first infers from images captured by camera 400-1 that the suspicious individual SU turned left at intersection 012 and headed toward intersection 011. The security support system 100b then selects camera 400-2, which can capture images of intersection 011, and acquires the images. Furthermore, the security support system 100b then infers from images captured by camera 400-1 that the suspicious individual SU turned right at intersection 011 and headed toward intersection 021. The security support system 100b then selects camera 400-3, which can capture images of intersection 021, and acquires the images. By repeating this operation, the suspicious person SU is tracked and an image is acquired.

[0039] By transmitting such a plurality of images to the terminal 200a of the security officer heading to the facility TF, it becomes possible for the security officer to take appropriate action. Note that, although the above example has been described with reference to tracking of a suspicious person SU, it is also possible to track a suspicious vehicle using a similar procedure.

[0040] As described above, according to this embodiment, it is possible to notify the terminal 200a of a security officer heading to facility TF of the movements and destinations of people and vehicles found in the vicinity of facility TF.

[0041] [Third Embodiment] Next, a third embodiment in which a function for transmitting images before receiving an abnormality notification is added to a security guard support system will be described in detail with reference to the drawings. FIG. 10 is a block diagram showing the configuration of a security guard support system 100c according to the third embodiment of the present disclosure. The difference from the first embodiment shown in FIG. 4 is that an image recording device 500 is disposed between the security guard support system 100c and the camera 400, and the security guard support system 100c is able to acquire images from the image recording device 500. Other configurations and operations are the same as those of the first embodiment, so a description thereof will be omitted and the following will focus on the differences.

[0042] The image recording device 500 is a device that stores images received from the camera 400 for a certain period of time, in association with the camera's ID, etc. The image recording device 500 may be a dedicated device, or may be a device used for traffic monitoring, traffic violation detection, etc.

[0043] Next, the operation of this embodiment will be described in detail with reference to the drawings. Fig. 11 is a flow chart showing the operation of a security guard support system 100c according to a third embodiment of the present disclosure. The difference from the first embodiment shown in Fig. 6 is that in step S102a, the security guard support system 100c acquires images including past images taken a predetermined time prior to the time when the abnormality report was received from the image recording device 500. Also, Fig. 11 omits the process of selecting images containing people or vehicles. The other operations are the same as those of the first embodiment, and therefore will not be described again.

[0044] According to this embodiment, for example, as shown in FIG. 12 , it is possible to transmit an image of the periphery of the facility TF before receiving an abnormality report to the terminal 200a of the security officer. In a particularly desirable form, as shown in FIG. 12 , it is possible to capture an image of a suspicious person approaching the facility TF, attempting to enter, and leaving the facility TF. As with the first embodiment, it is also possible that the received image does not show any people or vehicles. Even in this case, according to this embodiment, it is possible to consider the possibility that the suspicious person or vehicle is hiding, has escaped using a different route, or has malfunctioned the security system 300.

[0045] [Fourth Embodiment] Next, a fourth embodiment in which the camera selection method is changed depending on the content of the abnormality report will be described in detail with reference to the drawings. Fig. 13 is a block diagram showing the configuration of a security guard support system 100d according to the fourth embodiment of the present disclosure. The difference from the first embodiment shown in Fig. 4 is the functions of the receiving means 101d and the acquiring means 102d of the security guard support system 100d. Since the other configurations and operations are the same as those of the first embodiment, their explanation will be omitted and the description will focus on the differences.

[0046] The security system 300 detects abnormalities in the facility TF, including the type of abnormality, and reports the abnormality. The receiving means 101d has a function to receive abnormality reports transmitted from the security system 300 in the facility TF, as well as a function to extract information indicating the type of abnormality contained in the abnormality report and send it to the acquiring means 102d.

[0047] The acquisition unit 102d has a function of selecting the camera from which to acquire the image based on the type of abnormality report. For example, if the abnormality report includes information indicating that an intrusion into the facility TF has been detected, the acquisition unit 102d operates to increase the number of selected cameras 400. Figure 14 is a diagram showing, with dashed lines, the range of cameras selected when the abnormality report includes information indicating that an intrusion into the facility TF has been detected. In this way, by increasing the range of cameras 400 from which images are acquired, it is possible to improve the detection rate of suspicious individuals or suspicious vehicles that have committed or attempted intrusion.

[0048] Furthermore, for example, if the abnormality report includes information indicating the detection of a suspicious person or vehicle in the vicinity of the facility TF and its location, the acquisition unit 102d selects a camera capable of grasping the presence or absence of the suspicious person or vehicle based on the location information included in the abnormality report. Figure 15 is a diagram showing the camera selection range indicated by a dashed line when information indicating the detection of a suspicious person or vehicle in the vicinity of the facility TF is included. In this way, when monitoring a suspicious person or vehicle in the vicinity of the facility TF, the acquisition unit 102d narrows down the cameras 400 to be selected to those in the vicinity of the suspicious person or vehicle. This prevents other people or vehicles from being mistakenly identified as suspicious people or vehicles, thereby improving the capture rate of suspicious people or vehicles.

[0049] The security support system 100d, which operates as described above, makes it possible to appropriately change the images to be acquired depending on the type of abnormality occurring in the facility TF. While the examples in FIGS. 14 and 15 illustrate cases where an intrusion into the facility TF and the presence of a suspicious person or vehicle in the vicinity of the facility TF are detected, the range of cameras to be selected may also be changed when other types of abnormality reports are received. For example, in the event of a disaster or other disaster, in order to easily grasp the surrounding situation, the entire area of ​​the surrounding roads may be targeted for image acquisition, as shown in FIG. 14. Furthermore, if the abnormality report is about a malfunction of internal equipment in the facility TF, control may be exercised to suppress image acquisition.

[0050] Fifth Embodiment Next, a fifth embodiment in which recognition results of people and vehicles can be superimposed on an image transmitted to a terminal will be described in detail with reference to the drawings. FIG. 16 is a block diagram showing the configuration of a security guard support system 100e according to the fifth embodiment of the present disclosure. The fifth embodiment differs from the first embodiment shown in FIG. 4 in that an identification unit 106 and a feature information storage unit 107 are added to the security guard support system 100e. Other configurations and operations are the same as those of the first embodiment, so a description thereof will be omitted and the following will focus on the differences.

[0051] The feature information storage means 107 stores, for each facility under guard, feature information on the appearance of persons to be identified by the identification means 106. Possible persons to be identified include a group of persons who have the authority to enter and exit the facility TF (a whitelist), or a group of persons who should be prohibited from entering and exiting the facility TF (a blacklist). In addition, the feature information used may be feature information that can be used to perform authentication using an image, such as feature data for facial recognition of these persons.

[0052] The identification means 106 uses the feature information stored in the feature information storage means 107 to identify a person appearing in the image received from the acquisition means 102. When the identification means 106 has succeeded in identifying a person appearing in the image, the identification means 106 performs a process of superimposing information about the person who has been successfully recognized in the image on the image received from the acquisition means 102.

[0053] FIG. 17 is a flowchart illustrating the operation of the security guard support system 100e according to the fifth embodiment of the present disclosure. The fifth embodiment differs from the first embodiment illustrated in FIG. 6 in that steps S114 to S115 are added after image selection. The security guard support system 100e selects an image containing a person or vehicle from among the acquired images (step S103) and then attempts to identify the person in the image (step S114). If the security guard support system 100e successfully identifies the person in the image, it superimposes the identification result on the image sent to the transmission means 103 (step S115). If the security guard support system 100e fails to identify the person in the image in step S114, it may superimpose information such as "unknown" as the recognition result on the image sent to the transmission means 103.

[0054] 18 is a diagram illustrating the operation of the security guard support system 100e according to the fifth embodiment of the present disclosure. As shown in FIG. 18, when the person in the image is identified as A, the security guard support system 100e transmits an image on which the recognition result is superimposed to the terminal 200a.

[0055] As described above, according to this embodiment, it is possible to provide information about a person appearing in an acquired image to a security officer heading to facility TF. For example, if person A is a habitual burglar, the security officer can report the incident to the police early, which can be useful in conducting checkpoints and strengthening patrols. Furthermore, for example, if person A is a staff member or user of facility TF, the security officer can take action such as contacting the staff member or user.

[0056] In the above embodiment, the identification unit 106 is described as identifying people appearing in an image, but the identification unit 106 may also identify vehicles. In this case, the characteristic information storage unit 107 may store license plate information and characteristic information about the exterior of the vehicle. The identification unit 106 uses this information to identify the vehicle and superimposes the identification result on the image.

[0057] (Regarding Hardware Configuration) In each embodiment of the present disclosure, each component of each device represents a functional unit block. Some or all of the components of each device are realized by an arbitrary combination of an information processing device 900 and a program, for example, as shown in FIG. 19 . FIG. 19 is a block diagram showing an example of the hardware configuration of the information processing device 900 that realizes each component of each device. The information processing device 900 includes, as an example, the following configuration: - CPU (Central Processing Unit) 901 - ROM (Read Only Memory) 902 - RAM (Random Access Memory) 903 - Program 904 loaded into RAM 903 - Storage device 905 that stores the program 904 - Drive device 907 that reads and writes to a recording medium 906 - Communication interface 908 that connects to a communication network 909 - Input / output interface 910 that inputs and outputs data - Bus 911 that connects each component

[0058] Each component of each device in each embodiment is realized by the CPU 901 acquiring and executing a program 904 that realizes the function. That is, the CPU 901 in FIG. 19 selects the camera closest to the target facility, executes a program for acquiring images and a program for transmitting images to a predetermined terminal, and performs processing to update each calculation parameter stored in the RAM 903, the storage device 905, etc. The program 904 that realizes the function of each component of each device is stored in the storage device 905 or the ROM 902 in advance, for example, and is read by the CPU 901 as needed. The program 904 may be supplied to the CPU 901 via the communication network 909, or may be stored in advance on the recording medium 906, and the drive device 907 may read the program and supply it to the CPU 901.

[0059] Furthermore, this program 904 can display the processing results, including intermediate states, at each stage as necessary on a display device, or can communicate with the outside via a communication interface. Furthermore, this program 904 can be recorded in a computer-readable (non-transitive) storage medium.

[0060] There are various variations in the method of realizing each device. For example, each device may be realized by any combination of a separate information processing device 900 and a program for each component. Furthermore, multiple components of each device may be realized by any combination of a single information processing device 900 and a program. That is, the first to fifth embodiments can be realized by a computer program that causes the processors installed in these devices to execute the above-described processes using their hardware.

[0061] In addition, some or all of the components of each device may be realized by other general-purpose or dedicated circuits, processors, etc., or a combination of these. These may be configured by a single chip, or by multiple chips connected via a bus.

[0062] Some or all of the components of each device may be realized by a combination of the above-mentioned circuits and programs.

[0063] When some or all of the components of each device are realized by multiple information processing devices, circuits, etc., the multiple information processing devices, circuits, etc. may be centrally or decentralized. For example, the information processing devices, circuits, etc. may be realized as a client-server system, a cloud computing system, or the like, in a form in which each device is connected via a communication network.

[0064] It should be noted that the above-described embodiments are preferred embodiments of the present disclosure, and the scope of the present disclosure is not limited to only the above-described embodiments.
