Abstract

The invention provides a tracking device and a method for solving multiple-target meeting dodging, which can solve the problem of multiple-target meeting dodging. The method comprises: extracting target characteristics in a target image, wherein the target characteristics comprise target position, a column diagram and speed, and outputting the characteristics; according to the position and the speed of a target in the previous frame, predicting the position of a target in the current frame; according to the position of each target, judging whether targets are mutually dodged/ separated; enrolling a dodged target into a dodged group, and removing a separated target from the dodged group; judging a single target, calculating the characteristic matching factor of each single target and the single target prospect, and inputting the matching factor into a matching factor matrix so as to bring convenience for a matching decision in the later stage; selecting the optimal matching pair from the matching factor matrix, and outputting the optimal matching pair; according to the matching result, updating target information which comprises size, area and the column diagram; and finishing target state conversion, deleting a lost target, generating a new target and the like.

Description

technical field [0001] The invention relates to image processing and video monitoring, in particular to a tracking device and method for solving multi-target intersection and occlusion. Background technique [0002] Moving target detection and tracking are the basis of intelligent video surveillance technology, and its detection results and tracking results directly affect the false alarm rate and false alarm rate of later event detection (such as: intrusion, left items, stolen items, vehicles driving in the wrong direction, etc.) . Therefore, the methods of moving target detection and tracking have received extensive attention. [0003] The Chinese patent application with publication number CN 1875379A discloses a method and device for object tracking in video images, which considers the range and variance of each matching feature. The Chinese patent application with the publication number CN 101017572A discloses a method for tracking non-rigid objects in a frame video se...
