Abstract

The invention discloses an overlapped domain dual-camera target tracking system and method. According to the system, an HSV-based space background weighted Meanshift algorithm is connected with an improved visual field boundary target. According to the target tracking algorithm, a relatively-independent tracking task is executed on a video sequence collected by each camera within the visual field range of the camera through a front-end single-camera tracking subsystem, relevant information of the tacked target is obtained, data communication between the cameras is achieved by utilizing a target connection algorithm, and then high-class video processing processes like behavior judgment are carried out.

Description

technical field [0001] The present invention uses two fixed cameras to track and analyze moving targets in overlapping fields of view, and applies the theory related to target detection and tracking under a single camera to a dual-camera tracking system to realize continuous tracking of targets under the dual-cameras. Background technique [0002] With the continuous expansion of the scale of the intelligent monitoring system and the increasingly complex environment, in order to achieve continuous target tracking, it becomes more and more difficult for the monitoring system using a single camera to meet the above requirements. In this case, multi-camera object tracking comes into being. Multi-camera target tracking technology is an important development direction of intelligent video surveillance system. It covers computer vision, artificial intelligence, pattern recognition and information fusion. Based on the combination of multiple cameras to monitor important places, th...
