Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a schematic structural diagram of a video monitoring system provided by Embodiment 1 of the present invention. As shown in FIG.

Wherein, the video surveillance platform 13 is used to obtain the video surveillance request reported by the business application unit, the video surveillance request including the location information that the business application unit needs to monitor; matching the location information that needs to be monitored, and obtaining the location information that needs to be monitored the camera corresponding to the orientation information, and send the video stream of the camera corresponding to the orientation information to be monitored to the service application unit;

The service application unit 15 is configured to report the video monitoring request to the video monitoring platform; and receive the video stream of the camera corresponding to the position information to be monitored issued by the video monitoring platform.

Specifically, the position of the camera 11 in the video surveillance system can be pre-deployed. In this embodiment, one or more cameras are pre-deployed at the site to be monitored in the video surveillance system. Wherein, if multiple cameras are deployed, the site to be monitored can be Full coverage, and can temporarily turn off commands such as steering and telescopic control of the camera. If multiple business application units monitor an area at the same time, when switching the monitoring angle, you only need to select the video stream of the camera in different directions to realize different monitoring. Azimuth monitoring.

As shown in FIG. 2 , it is a schematic diagram of an example camera deployment in the video surveillance system provided by Embodiment 1 of the present invention, wherein, at the site that needs to be monitored, cameras 11 in the following directions can be deployed, for example: on, The cameras 11 are respectively arranged in the downward, east, west, south, and north directions. The deployment orientation in FIG. 2 is only an example, and it is not a specific limitation on the orientation of the cameras. The orientation of the cameras can also be adopted in other ways. For example, the cameras can also be arranged according to the angle, such as deploying a camera at an interval of 30 degrees, or deploying obliquely upward or downward cameras. In the video surveillance system, the number and orientation of cameras deployed at each site that needs to be monitored can be determined according to the development of the business application unit 15 and the heat of the site, etc. If the site that needs to be monitored is monitored by more and more business application units , you can increase the number of cameras and deploy denser cameras. As shown in FIG. 2 , after the deployment of the cameras 11 at the site to be monitored is completed, the video monitoring service can be provided for the multi-channel service application unit 15 through the video monitoring platform 13 . Among them, the method for the video monitoring platform to provide video monitoring services for multiple business application units is specifically: the video monitoring request reported by the business application unit to the video monitoring platform, which carries the location information to be monitored, such as: the position, angle, direction, etc. of the camera parameters, no need to directly request video from the camera. According to the parameters in the video monitoring request, the video monitoring platform matches and obtains the video stream of the corresponding camera, and returns the matching video stream to the service application unit. Wherein, the matching process may be fuzzy matching or exact matching, and in fuzzy matching, the closest matched camera may be used as the matching result.

Specifically, the business application unit can be set not to directly access the control camera (or be set to not start action commands such as the angle rotation of the control camera), and the business application unit reports to the video monitoring platform which position, which angle, and direction of the camera it needs. Video data is the location information that needs to be monitored. The video monitoring platform determines which cameras' video data, that is, video stream, to send to the business application unit according to the parameters reported by the business application unit. For the video stream reported by each camera, the video surveillance platform can obtain parameters such as the position, angle, and direction of the video stream. The acquisition methods include two methods:

Method 1. If the camera can report its own position, angle, and direction parameters, it can report the camera’s position, angle, and direction parameters while importing video streams to the video surveillance platform. Of course, the camera can also report to the video surveillance platform separately. Report the camera's position, angle, direction and other parameters.

Method 2. If the camera cannot report its own position, angle, and direction parameters, the video surveillance platform can record the camera’s position, angle, and direction parameters, such as: manually input or import through the interface, and then report all the parameters of the camera. The video stream is processed according to the position, angle, direction and other parameters recorded by the video surveillance platform.

Among them, after the camera is deployed, the video monitoring platform can also control the camera to change the angle, direction, etc., and only when the orientation information of all the deployed cameras differs greatly from the orientation information to be monitored, the matching module can be requested through the video 25 According to the matching result, instruct the direction adjustment module 28 to adjust the position of the camera that is closer to the orientation information that needs to be monitored. If the position information of a certain camera is changed, the video parameter management module 21 of the video monitoring platform can update the adjusted The camera's new position, angle, direction and other parameters, for example, can be entered manually, automatically judged and entered, or updated according to the orientation information reported by the camera. After the update, when any business application unit requests surveillance video, the video surveillance platform will perform matching according to the updated new parameters.

For example, if multiple cameras are deployed at an intersection, they can be divided into cameras that focus on pedestrians, cameras that focus on vehicles, cameras that focus on east-west roads, and cameras that focus on north-south roads according to the needs of the scene. After classification, these types of videos can appear on the monitoring interface used by each user, that is, the business application unit. Each business application unit does not need to control the camera, but only needs to access the video monitoring that it cares about. It can support concurrent access by multiple users. webcam video.
