Abstract

The invention provides a target tracking method and device. The method includes the steps of: collecting a depth image and a color image of a current video image; obtaining at least two target regions in the depth image according to the depth image; performing face detection on the color image corresponding to each target region, and obtaining a face region corresponding to each target region; and when the distance between a first face region corresponding to a first target region and a second face region corresponding to a second target region is smaller than a preset threshold value, using a coring coherent filter to track the first face region and the second face region. The target tracking method realizes accurate tracking of multiple targets when there is the target shadow interference in the multiple target tracking and the shielding interference during target interaction.

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 ...
