Abstract

The invention provides a multi-moving-target tracking method, so that effectiveness of the multi-moving-target tracking method can be guaranteed. The method comprises: moving targets in a current frame of image are obtained, wherein the obtained moving targets in the current frame of image are used as tracking targets; a coordinate of a barycentric coordinate of each tracking target in a next frame of image is predicted, and a distance between the coordinate of the predicted barycentric coordinate of each tracking target in the next frame of image and a barycentric coordinate of each moving target in the next frame of image is determined; for one tracking target in the current frame of image, a moving target closest to one tracking target in the current frame of image is determined as a to-be-matched target in the next frame of image according to the determined distance between the coordinate of the predicted barycentric coordinate of each tracking target in the next frame of image and the barycentric coordinate of each moving target in the next frame of image; and feature matching tracking is carried out on the tracking target and the to-be-matched target. The method is suitable for the moving target detection and tracking technical field.

Description

technical field [0001] The invention relates to the technical field of moving target detection and tracking, in particular to a multi-moving target tracking method. Background technique [0002] With the continuous development of computer technology, communication technology, image processing and other technologies, the focus of computer vision research has gradually shifted from the study of static images to the study of dynamic image sequences, that is, the study of visual analysis of moving objects. In real life, a large amount of meaningful visual information is contained in motion, and the problem of detection and tracking of moving objects based on vision is an important research topic in the field of computer vision. [0003] The traditional moving target tracking algorithm based on a single feature has a better tracking effect in a simple environment, but it is difficult to correctly track a certain target in a complex environment. However, in practical applications...
