Problems solved by technology

The problem with target detection in fixed mode is: if the resolution of the target needs to be increased, the monitored scene can only be concentrated in a certain part, for example, the boarding entrance of the airport, etc.
If it is necessary to increase the monitoring range, it is impossible to guarantee the depiction of the details of the intrusion target in the monitoring screen

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The present invention is based on the double-camera linkage structure of the video moving target close-up tracking and monitoring method, which adopts the linkage structure of two cameras. The so-called dual-camera linkage structure refers to setting up a fixed panoramic surveillance camera to complete the panoramic surveillance of the entire surveillance area. Another camera mounted on a rotatable gimbal with two degrees of freedom completes the close-up tracking of the locked target. When the panoramic surveillance camera finds the target, it judges the speed and direction of its movement, and drives the close-up tracking camera to rotate and track with the target's movement. The so-called close-up tracking means that the monitoring screen of the tracking target camera only has the target. In this way, the correct identification of ...

Abstract

The double-camera linkage structure-based close-up tracking and monitoring method for video moving targets disclosed by the present invention uses a panoramic monitoring camera to identify targets in the monitoring area, determine the position, running speed and direction of the target, and after locking and tracking the target, the target information is Pass it to the close-up tracking camera that is controlled by the pan / tilt. The close-up tracking camera will close-up the locked target, zoom in and track it, and display the close-up picture of the target, so as to obtain more information about the target. It can not only monitor the panorama, but also automatically judge suspicious targets, and realize the function of close-up tracking.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and relates to a method for monitoring a video moving target, in particular to a method for monitoring a video moving target by using a double-camera linkage structure. Background technique [0002] With the continuous development of computer video image processing technology, as well as the urgent needs of security, anti-terrorism and other fields, the intelligent monitoring system requires a certain degree of automation in the behavior analysis of intrusion targets. [0003] In order to ensure that moving targets can be detected, the camera settings of the video surveillance system are mostly in a fixed mode. The problem of target detection in fixed mode is: if the resolution of the target needs to be increased, the monitored scene can only be concentrated in a certain part, for example, the boarding gate of the airport, etc. If it is necessary to increase the monitoring range, it is ...
