Dome camera automatic tracking control method and dome camera automatic tracking control system based on moving target detection

Abstract

The invention relates to a dome camera automatic tracking control method and a dome camera automatic tracking control system based on moving target detection. In the method, box camera video images are acquired in real time, the box camera video images are detected and tracked through a moving target detection and tracking algorithm and angle information of the dome camera aligned with the movingtarget is calculated; a dome camera holder is controlled according to the angle information to horizontally and/or vertically rotate for a corresponding angle, and the center of the dome camera is guaranteed to be aligned with the moving target and the moving target is tracked, until tracking time of the moving target is up or the target disappears. The method not only can guarantee monitoring field range of a panorama box camera, but also can automatically control the dome camera to track and enlarge the moving target in the panorama box camera, thus, definition and monitoring effect of the moving target in a monitoring scene are guaranteed, particularly for a moving object, the method can further guarantee monitoring quality and reduce labor cost of monitoring personnel.

Description

technical field [0001] The invention mainly relates to the fields of video monitoring and image processing, in particular to an automatic tracking control method and system of a ball machine based on moving target detection. Background technique [0002] In the field of video surveillance, the application of high-definition network digital surveillance has replaced traditional analog surveillance, and the technology of high-definition network digital surveillance has continued to use the control technology of traditional analog surveillance. [0003] At present, the triggers on the market (including high-definition network triggers and simulated triggers) have the problem of being invisible or unclear in large open scenes such as squares, and they can only use the Pelco-D or Pelco-P protocol through RS485 Take manual control. When the monitoring staff finds a suspicious target from the monitoring screen of the dome machine, they need to manually control the rotation of the ...

Problems solved by technology

[0005] In view of the above defects of the prior art, the object of the present invention is to provide a method and system for automatic tracking and control of dome machines based on moving target detection, which can effectively solve the problem of the low degree of automation of dome machines in traditional video surveillance and the need for monitoring personnel to manually control the dome. It can not only ensure the monitoring field of view of the panoramic bolt, but also automatically control the ball camera to track and zoom in on the moving targets in the panoramic bolt to ensure the clarity of the moving targets in the monitoring scene. And the monitoring effect, especially for moving objects, can further ensure the quality of monitoring and reduce the labor cost of monitoring personnel
