Abstract

A multi-camera monitoring system and tracking method based on stereoscopic video dynamic tracking, relating to the technical field of video monitoring and tracking; the system includes a stereoscopic video panoramic camera module with at least two panoramic cameras for forming digital image sequences The image acquisition module is used for computing and processing to generate the image processing module of the three-dimensional control signal of each target, respectively connected to the tracking camera module, the manual controller, and the data communication and control module of the monitoring center, and is equipped with more than one tracking camera for respectively A tracking camera module for monitoring and tracking each abnormal or moving target; the tracking method includes a moving target detection and segmentation algorithm for a digital image sequence, a multi-moving target extraction algorithm and a target three-dimensional position information fusion algorithm; the present invention can respectively track and monitor multiple For different targets, the tracking deviation of the target position can be reduced, and a clear and complete tracking target image can be obtained.

Description

technical field [0001] The present invention relates to video monitoring and tracking technology, in particular to a method of using a dual-lens camera or two cameras to obtain three-dimensional information of a monitoring target within its field of view, and can intelligently judge and detect multiple abnormal or moving targets while performing panoramic monitoring And dynamically control the tracking camera to track the target respectively and the monitoring system technology of self-adaptive scaling. Background technique [0002] With technological progress and changes in the international situation, the intelligent monitoring system has become an inevitable development trend. Security monitoring systems are essential in important places such as security, transportation, finance, energy, and communications. The purpose of the video surveillance system is to discover and report abnormal situations or moving targets in the monitoring scene in time and save their records as ...

AI Technical Summary

Problems solved by technology

There are three main defects in this system: First, from the perspective of principle, the system uses a single panoramic camera, which can only obtain the two-dimensional position information of the center point of the abnormal or moving target on the projection plane of the camera, and cannot determine the distance of the target relative to the camera Information, that is, depth position information, the system essentially tracks the two-dimensional projection of the target on the camera projection plane, rather than the target itself in three-dimensional space

This algorithm has strong real-time performance, but there is a certain deviation in the detection of some incoherent motion areas and isolated motion areas, resulting in errors in the center position coordinates of the moving target projection.

3. From a practical point of view, the system can only detect and track a single anomaly or moving target. In the case of multiple moving targets, the patent does not mention how the system will handle and track

The existing monitoring system is still unable to realize the functions of real-time and precise positioning, tracking and monitoring of multiple abnormalities or moving targets at the same time of panoramic monitoring
