Description
Technical Field
The present invention relates to a video surveillance system and a surveillance video display method, and is suitable for use in a video surveillance system for monitoring intrusion of suspicious persons into stations, buildings, and the like, and failures of equipment provided in the stations and buildings, for example.
Background
In recent years, in order to reduce labor costs, a monitored site system including a monitoring camera and a recording device for recording images captured by the monitoring camera is installed at a monitored site, and monitoring operations at stations, buildings, and the like are performed by arranging a resident security guard or the like in place of an object to be monitored (hereinafter, referred to as a monitored site).
In this case, a monitoring site where a resident monitoring person resides is installed at a site distant from the site to be monitored, such as a monitoring site at a station and an office site of an owner of a building. The monitoring person continuously monitors the state of the monitored site by displaying, on a monitoring terminal such as a personal computer, a video image of a monitoring camera transmitted from a monitored site system installed at the monitored site via a communication network such as the internet. When a suspicious person invades a monitored site, a device provided in the monitored site has failed, or the like, a monitoring person contacts a security company, a patrol officer, or the like to take measures at the monitored site.
However, when monitoring a wide range of sites to be monitored, it is common to install a plurality of monitoring cameras on the sites to be monitored, and to display images of the monitoring cameras in a divided manner on a screen of a monitoring terminal of the monitoring site. In this case, the imaging area of each of 1 monitoring camera is small, and the monitoring person needs to confirm the plurality of images displayed in divided form while grasping the positional relationship of the monitoring cameras that capture the respective images.
In order to solve such a problem, for example, patent document 1 discloses an invention that combines images of a plurality of monitoring cameras in addition to images of individual monitoring cameras so that a monitoring person can grasp a positional relationship of each monitoring camera in order to remotely grasp a state of a site to be monitored in detail.
However, when an abnormal situation of a site is confirmed from an image at the time of an illegal intrusion or a failure of equipment, it is necessary to set a monitoring camera at a high position in order to acquire a wide-range image. However, when the monitoring camera is disposed at a high place, there is a problem that detailed information such as the face of an illegal intruder, the color and age of clothes cannot be grasped from the image thereof.
In addition, when the monitoring camera is installed at a high place, there are problems such that an illegal intruder cannot be tracked due to an obstacle such as a roof, or a range of an apparatus abnormality such as smoke, water leakage cannot be completely grasped, or an operation at the time of switching the monitoring camera cannot be intuitively performed.

Detailed Description
An embodiment of the present invention is described in detail with reference to the following drawings.
(1) Structure of video surveillance system of the present embodiment
In fig. 1, reference numeral 1 denotes a video surveillance system according to the present embodiment as a whole. The video surveillance system 1 is configured by connecting 1 or a plurality of monitored site systems 10, 1 or a plurality of surveillance site systems 30, and a management server 40 via a network 20 such as the internet.
The monitored site system 10 is a system in which monitored sites such as stations and buildings are installed at the monitored sites, and is configured to include a plurality of 1 st monitoring cameras 13A, 13B, 13C, and 13D, a plurality of 2 nd monitoring cameras 14A and 14B, a recording device 11, and a communication device 12.
The 1 st monitoring cameras 13A to 13D are monitoring cameras for capturing overhead images around the site to be monitored, and are each provided at a high position such as a roof of the site to be monitored 15, as shown in fig. 2. In this case, the installation locations of the 1 st monitoring cameras 13A to 13D are determined so that the 1 st monitoring cameras 13A to 13D can cover the entire periphery of the monitored site 15 to perform imaging, and the adjacent 1 st monitoring cameras 13A to 13D overlap each other in part of their imaging ranges.
The 2 nd monitoring cameras 14A and 14B are monitoring cameras for capturing details of the site, and are provided at positions lower than the 1 st monitoring cameras 13A to 13D, for example, at positions 2 to 3m higher from the ground.
The recording device 11 is configured to include a large-capacity storage device such as a hard disk device, for example, and accumulates video data of captured images output from the 1 st monitoring cameras 13A to 13D and the 2 nd monitoring cameras 14A and 14B, respectively. In addition, a time code indicating the shooting time is embedded in the video data.
The communication device 12 is configured by, for example, an NIC (Network Interface Card) or the like, and reads out the video data from the 1 st monitoring cameras 13A to 13D and the 2 nd monitoring cameras 14A and 14B accumulated in the recording device 11 from the recording device 11 in response to a request from the management server 40, and transmits the video data to the management server 40 via the Network 20.
The management server 40 is a server device that acquires video data from the recording devices 11 of the monitored site systems 10, processes the acquired video data to generate a predetermined monitoring screen described later with reference to fig. 3 and 4, and transmits screen data of the generated monitoring screen to each monitoring site system 30. The management server 40 is configured to include a CPU (Central Processing Unit) 42, a memory 50, an auxiliary storage device 60, and a communication device 41.
The CPU42 is a processor responsible for controlling the overall operation of the management server 40. The memory 50 is formed of, for example, a volatile semiconductor memory, and functions as a work memory of the CPU 42. A later-described image acquisition unit 51, image processing unit 52, icon display unit 53, and screen transmission unit 54 are also stored and held in the memory 50.
The auxiliary storage device 60 is configured by a large-capacity nonvolatile storage device such as a hard disk device or SSD (Solid State Drive), and stores and holds programs and data for a long period of time. On the storage area provided by the auxiliary storage device 60, a local information storage area 61, an IP address storage area 62, a picture data storage area 63, and an icon display position storage area 64, which will be described later, are secured.
The communication device 41 is configured by a NIC or the like, and performs protocol control when performing communication with each monitored site system 10 and each monitoring site system 30 via the network 20.
The monitoring station system 30 is a system installed at a monitoring station where a monitoring person who monitors a monitored station resides. In the case of the present embodiment, since the monitoring stations are provided in association with the respective monitored stations 15, the monitoring station system 30 is also provided in association with the monitored station system 10.
The monitoring station system 30 is configured to include a monitoring terminal 31. The monitoring terminal 31 is configured by, for example, a personal computer, a workstation, a mobile phone terminal, or the like, and displays the monitoring screen based on screen data transmitted from the management server 40 via the network 20.
(2) Structure of monitoring screen
Fig. 3 shows a configuration example of a 1 st monitoring screen 70 displayed on the monitoring terminal 31 of the monitoring site system 30 based on the screen data transmitted from the management server 40. As shown in fig. 3, on the 1 st monitoring screen 70, reduced images of the images captured by the 1 st monitoring cameras 13A to 13D installed in the monitored site 15 that is the monitoring target of the monitoring site system 30 are displayed in the divided image display areas 71 to 74, respectively.
Further, an image composition button 75 is displayed on the lower right side of the 1 st monitor screen 70, and by clicking the image composition button 75, the display screen of the monitor terminal 31 can be switched from the 1 st monitor screen 70 to the 2 nd monitor screen 80 shown in fig. 4.
The 2 nd monitoring screen 80 is configured to include an overhead image display area 81 and a split screen button 82. Then, an overhead image is displayed in the overhead image display area 81, and a composite image obtained by combining the images captured by the respective 1 st monitoring cameras 13A to 13D provided at the monitored site 15 is displayed around the graph 83 (an area indicated by oblique lines in fig. 4) indicating the planar shape of the corresponding monitored site 15, so as to be displayed just like the monitored site is captured from directly above. The resolution of the overhead image is lower than the resolution of the images captured by the 1 st monitoring cameras 13A to 13D.
On the overhead image, 1 st icons 84A, 84B, 84C, and 84D are displayed at positions corresponding to the installation positions of the 1 st monitoring cameras 13A to 13D on the monitored site 15 (fig. 2), and 2 nd icons 85A and 85B are displayed at positions corresponding to the installation positions of the 2 nd monitoring cameras 14A and 14B on the monitored site 15. In the case of the present embodiment, the 1 st icons 84A to 84D are displayed as double circles, and the 2 nd icons 85A and 85B are displayed as triple circles, whereby the 1 st monitoring cameras 13A to 13D and the 2 nd monitoring cameras 14A and 14B on the overhead image can be easily recognized. Hereinafter, the images displayed on the overhead image by the 1 st and 2 nd icons 84A to 84D, 85A, and 85B are referred to as icon-attached overhead images.
In the 2 nd monitoring screen 80, by clicking the 1 st or 2 nd icons 84A to 84D, 85A, and 85B in the icon-attached overhead image displayed in the overhead image display area 81, the icon-attached overhead image displayed in the overhead image display area 81 can be switched to the images captured by the 1 st or 2 nd monitoring cameras 13A to 13D or the 2 nd monitoring cameras 14A and 14B corresponding to the 1 st or 2 nd icons 84A to 84D, 85A, and 85B.
In addition, on the 2 nd monitoring screen 80, by clicking an arbitrary position (an arbitrary position in the area where the composite image shown by oblique lines in fig. 4 is displayed) other than the graphic 83 showing the monitored site 15 in the overhead image with an icon, the overhead image with an icon displayed in the overhead image display area 81 can be switched to the image shot by the 1 st monitoring cameras 13A to 13D or the 2 nd monitoring cameras 14A and 14B that are shooting the position.
In addition, on the 2 nd monitoring screen 80, the display screen of the monitoring terminal 31 can be switched to the 1 st monitoring screen 70 by clicking the divided screen button 82.
(3) Logical structure of management server
As means for generating the above-described 1 st and 2 nd monitoring screens 70 and 80, the above-described image acquisition unit 51, image processing unit 52, icon display unit 53, and screen transmission unit 54 are stored in the memory 50 of the management server 40, and the local information storage area 61, IP address storage area 62, image data storage area 63, and icon display position storage area 64 are secured in the storage area provided by the auxiliary storage device 60 of the management server 40.
The image acquisition unit 51 is a program having the following functions: the image data of the captured images of the 1 st monitoring cameras 13A to 13D and the 2 nd monitoring cameras 14A and 14B respectively accumulated in the recording device 11 of each monitored site system 10 is acquired. The video acquisition unit 51 stores and manages the acquired video data in a video data storage area 63 in the auxiliary storage device 60.
The image processing unit 52 is a program having the following functions: for each monitored site 15, the reduced image described above with reference to fig. 3 or the overhead image displayed in the overhead image display area 81 of the 2 nd monitoring screen 80 described above with reference to fig. 4 is generated using the corresponding image data stored in the image data storage area 63.
The icon display unit 53 is a program having the following functions: icon-attached overhead images in which the 1 st and 2 nd icons 84A to 84D, 85A, and 85B described above are displayed on the overhead image generated by the image processing unit 52 are generated for each monitored site 15.
The screen transmitting unit 54 is a program having the following functions: the image data of the reduced image generated by the image processing unit 52 and the image data of the overhead image with the icon generated by the icon display unit 53, and the screen data of the 1 st monitoring screen 70 described with reference to fig. 3 and the 2 nd monitoring screen 80 described with reference to fig. 4 are transmitted to the monitoring terminal 31 of the corresponding monitoring site system 30 for each monitored site 15.
Note that, although the processing subject of each process is sometimes described below as a "program", it goes without saying that the CPU42 actually executes the process in accordance with the "program".
On the other hand, various information (building name, region name, etc.) relating to each monitored site 15 is stored in the local information storage area 61 of the auxiliary storage device 60 of the management server 40, and the IP address of the communication device 12 of each monitored site system 10 is stored in the IP address storage area 62. These IP addresses are used to identify each monitored site system 10 individually.
In the video data storage area 63 of the auxiliary storage device 60, video data acquired by the video acquisition unit 51 from each monitored site system 10 is stored, the icon display position storage area 64 stores position information (hereinafter, referred to as icon display position information) indicating the positions of the 1 st icons 84A to 84D and the 2 nd icons 85A and 85B on the overhead image of each monitored site to be displayed, shape information (hereinafter, referred to as building figure shape information) indicating the shape of the figure 83 of the monitored site 15 to be monitored to be displayed on the overhead image, and information (hereinafter, referred to as icon display form information) indicating the display forms such as the shapes, colors, and sizes of the 1 st and 2 nd icons 84A to 84D, 85A, and 85B.
Each of the above-described pieces of information stored in the local information storage area 61, the IP address storage area 62, and the icon display position storage area 64 is information that is registered in advance by a monitoring person using the monitoring terminal 31.
(4) Processing of management server at the time of generation of 2 nd monitoring screen
Fig. 5 shows a specific process flow of the monitoring screen generation process executed by the management server 40 when the 2 nd monitoring screen 80 is generated. The management server 40 generates screen data of the 2 nd monitoring screen 80 according to the processing procedure shown in fig. 5, and transmits the screen data to the monitoring terminal 31 of the corresponding monitoring site system 30.
In fact, in a state where the monitoring terminal 31 of the monitoring site system 30 displays the 1 st monitoring screen 70 described with reference to fig. 3, if the monitor clicks the image combination button 75, the management server 40 starts the monitoring screen generation process shown in fig. 5. Then, first, the video image acquisition unit 51 acquires video image data accumulated in the recording device 11 of the monitored site system 10 corresponding to the monitoring site system 30 (SP 11).
Actually, the video acquisition unit 51 reads the IP address of the monitored site system 10 corresponding to the monitoring site system 30 from the IP address storage area 62 of the auxiliary storage device 60, and transmits a video data transfer request (hereinafter, referred to as a video data transfer request) to the communication device 12 of the monitored site system 10 via the communication device 41 based on the read IP address.
Then, the communication device 12 of the monitored site system 10 that has received the video data transfer request transmits the video data of the respective captured videos of the 1 st monitoring cameras 13A to 13D and the 2 nd monitoring cameras 14A and 14B, which are stored in the recording device 11 at that time, to the management server 40. Then, if the video data is acquired in this manner, the video acquisition unit 51 stores the acquired video data in the video data storage area 63 of the auxiliary storage device 60, and then calls the video processing unit 52.
If called by the image acquisition unit 51, the image processing unit 52 generates an overhead image as described with reference to fig. 4 from the building figure shape information of the corresponding monitored site stored in the icon display position storage area 64 of the auxiliary storage device 60 and the image data output from the 1 st monitoring cameras 13A to 13D of the corresponding monitored site system 10 stored in the image data storage area 63 of the auxiliary storage device 60, and stores the image data of the generated overhead image in the image data storage area 63 of the auxiliary storage device 60 (SP 12). Then, the video processing unit 52 calls the icon display unit 53.
If called by the image processing unit 52, the icon display unit 53 reads the icon display position information and the icon display mode information for the monitored site 15 stored in the icon display position storage area 64 of the auxiliary storage device 60, and generates an overhead image with icons in which the 1 st icons 84A to 84D and the 2 nd icons 85A and 85B are displayed on the overhead image based on the image data stored in the image data storage area 63 of the auxiliary storage device 60, based on the read icon display position information and icon display mode information (SP 13). Then, the icon display unit 53 calls the screen transmission unit 54.
The screen transmitting unit 54, if called by the icon display unit 53, generates the 2 nd monitoring screen 80 in which the icon-attached overhead image generated by the icon display unit 53 is displayed in the overhead image display area 81 (fig. 4), and transmits the screen data to the monitoring terminal 31 of the corresponding monitoring site system 30 (SP 14). In this way, the monitoring screen generation process of the management server 40 is ended.
(5) Effects of the present embodiment
As described above, in the video surveillance system 1 according to the present embodiment, the management server 40 generates icon-attached overhead videos in which the 1 st icons 84A to 84D are displayed at the installation positions of the 1 st surveillance cameras 13A to 13D and the 2 nd icons 85A and 85B are displayed at the installation positions of the 2 nd surveillance cameras 14A and 14B, respectively, from the images captured by the 1 st surveillance cameras 13A to 13D, and displays the images on the surveillance terminal 31 of the surveillance site system 30. Therefore, the monitoring person can intuitively recognize the positional relationship between the 1 st monitoring cameras 13A to 13D and the 2 nd monitoring cameras 14A and 14B from the overhead image with the icon displayed on the monitoring terminal 31.
In the present image monitoring system 1, by clicking the 1 st icons 84A to 84D and the 2 nd icons 85A and 85B displayed in the icon-attached overhead image or clicking a position other than the graphic 83 indicating the monitored site 15 in the icon-attached overhead image, the captured images of the corresponding 1 st monitoring cameras 13A to 13D or 2 nd monitoring cameras 14A and 14B can be displayed.
Therefore, according to the image monitoring system 1, the monitoring person can easily and reliably grasp the status of the monitored site.
