A method and device for automatically confirming the field of view of a camera

Abstract

The invention discloses a method and device for automatically confirming the visual field of a camera. By querying the information point data around the camera and calculating the set of information points within the preset distance range of the camera, the picture of the scene around the camera sent by the camera is received. , and extract and analyze the information in the scene picture around the camera to obtain the identifiable information set in the scene around the camera, and combine the identifiable information in the identifiable information set in the scene around the camera with the information points within the preset distance range of the camera The information points in the set are matched, and the visual field of the camera is obtained according to the matching result. The device of the present invention includes an information point acquisition module, an identifiable information acquisition module and a visual domain acquisition module. The method and device of the present invention can quickly and automatically draw the visual field of each camera in the electronic map, saving manpower and material resources.

Description

technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to a method and a device for automatically confirming the visual field of a camera. Background technique [0002] With the development of technology, camera video surveillance based on electronic map presentation has been widely used in the current security monitoring industry. In the camera video surveillance system based on map presentation, the location of the camera can be intuitively viewed through the map, and Real-time video monitoring and scheduling of designated places on the map. Compared with traditional video monitoring platforms, electronic map-based monitoring platforms can provide better user experience. [0003] However, while the technology is constantly being updated, it is inevitable to encounter some other problems. In many video surveillance systems, although we have marked the cameras in the electronic map, the electronic map lacks the key camera vis...
