Open type 1+N gun-type camera and dome camera linkage system

Abstract

The invention discloses an open type 1+N gun-type camera and dome camera linkage system, and the system comprises a gun-type camera and dome camera integrated machine and N independent high-speed dome cameras, a network media video recorder, a streaming media management and control server and a client computer. A linkage process of the system comprises the following steps: 1) setting a connection transmission mode of a video stream and a control stream in the system; 2) dynamically adding information of N independent dome cameras associated with the gun-type camera and dome camera integrated machine by a user; 3) when the user performs frame selection to select a region of interest in a panoramic image, quickly and accurately focusing an integrated dome camera to the center of the region through cooperation of a client and a server; and 4) performing linkage control to control other independent dome cameras to rotate and focus on a target point. The open type 1+N gun-type camera and dome camera linkage system has the advantages of being capable of completely seeing 180-degree panorama, being capable of seeing magnified detailed images clearly, also being capable of cooperating with other close-distance high-speed dome cameras, capturing video images of the region of interest from multiple directions, thereby being more flexible and efficient.

Description

technical field [0001] The invention relates to the linkage problem between a plurality of speed dome machines and an all-in-one gun and ball machine in a video monitoring system, in particular to a gun and ball linkage system based on a camera coordinate system 1+N, belonging to the field of security video monitoring. Background technique [0002] In the Safe City Surveillance Project, high-definition video surveillance has been deployed in key areas, but because traditional video surveillance cannot capture the detailed information of the target in a large scene, it will ignore other surrounding targets when focusing on the details of the target. The effect of safety precautions cannot meet the requirements at all. Therefore, there is an urgent need for a modern security intelligent system that can "see" and "see clearly" the monitoring scene in the macro scene. [0003] The linkage method of current bolt and dome camera is aimed at single bolt and dome camera. For examp...

Problems solved by technology

The main problems are: 1) The bolt adopts ordinary high-definition bolt, the field of view is about 120 meters, the monitoring range is narrow, and it does not support the monitoring of large scenes with a panoramic view of 180 degrees; 2) The speed dome automatically recognizes and tracks moving targets, and cannot According to the needs of the administrator, zoom in and monitor the stationary target; 3) Only one dome camera that comes with the gun-ball linkage system can be controlled, and there is no ability to control other dome machines that have been set up by the security department. The degree of effective utilization of existing monitoring equipment resources not enough
