Video linkage system based on large scene video monitoring

Abstract

The invention belongs to the technical field of video monitoring, and specifically relates to a video linkage system based on large scene video monitoring. The system includes cameras, switches, a video analysis server, and a video display terminal module. The cameras include a front-end multi-channel camera, a ground camera, a high-point camera, and a cradle head camera; the video analysis serverperforms data acquisition, video stitching, fusion output, and command control on multiple front ends; and the video analysis server is connected to the video display terminal module via LAN / Internet. The system overcomes deficiencies in the prior art, and solves the problems of complex monitoring point positions, difficult querying, and existence of dead zones in conventional large scenes; and multi-camera coordinated linkage monitoring in large scene video is achieved for ground low-point camera images marked in video images of large scenes.

Description

Technical field [0001] The invention belongs to the technical field of video monitoring, and specifically relates to a video linkage system based on large scene video monitoring. Background technique [0002] Video surveillance is an important means of security management in public areas. It has been widely used and popularized, whether from analog cameras of hardware devices to current high-definition network cameras, or various intelligent analysis and linkages on software, video surveillance Technology has always received a high degree of attention and rapid development. [0003] Panoramic dynamic management and control of large public places such as crowded and complex squares, parks, airports, ports and other special areas to achieve full coverage of large scenes and detailed inspection of key areas to truly "see all", "see clearly", "Can manage." [0004] Break through the limitation of performing isolated intelligent analysis in each sub-lens of traditional video surveillanc...

Problems solved by technology

[0006] The purpose of the present invention is to provide a video linkage system based on large-scale video monitoring, which overcomes the shortcomings of the existing technology and solves the problems of complex monitoring points, difficult query, and blind spots in the existing large-scale scene, that is, there are large The overall monitoring of the scene can intuitively understand the distribution of ground cameras in the large scene picture, and at the same time, it can combine with the pan-tilt camera to capture details, providing mainly: the large-scene monitoring video picture output by the front-end multi-channel camera through splicing; the front-end pan-tilt The camera receives instructions, controls the pan-tilt camera to automatically rotate, zoom and focus, and obtains and outputs local detailed video images in the large-scene video image; the ground low-point camera image marked in the large-scene video image realizes multi-camera in the large-scene video Collaborative linkage monitoring
