Abstract

The invention provides a target tracking method and device. The method includes: acquiring a depth image and a color image of the current video image; acquiring at least two target areas in the depth image according to the depth image; performing face detection on the color image corresponding to each target area, and acquiring each The face area corresponding to the target area; when the distance between the first face area corresponding to the first target area and the second face area corresponding to the second target area is less than a preset threshold, a correlative correlation filter is used to The first human face area and the second human face area are tracked. The target tracking method provided by the present invention realizes accurate tracking of multiple targets when there is target shadow interference in multi-target tracking and occlusion interference when targets interact.

Description

technical field [0001] The invention relates to image processing technology, in particular to a target tracking method and device. Background technique [0002] Video monitoring is the physical basis for real-time monitoring of key departments or important places such as enterprises, commercial places, parks, etc. Management departments can obtain effective data, images or sound information through video monitoring. [0003] With the rapid development and promotion of current computer applications, how to realize the tracking of multiple targets in video surveillance has always been a research problem for technicians. The existing multi-target tracking method in video surveillance includes: obtaining the initial information of at least one target of interest from the tracking video, and selecting N0(t) targets of interest from the target of interest in order of feature salience from large to small as The initial tracking layer, and then according to the initial position of ...
