Video target tracking method and device in complex environment

Abstract

The invention discloses a video target tracking method and device in a complex environment. The method comprises the following steps: receiving the target image information of a tracking target inputted by a user, carrying out the feature extraction of the target image information of the tracking target, and obtaining the feature information of the tracking target; constructing a tracking target feature matrix based on the tracking target feature information; extracting target object feature information in the collected video information, and constructing a target object feature matrix based on the target object feature information; obtaining a to-be-tracked target based on matching of the tracking target feature matrix and the target object feature matrix; locking the to-be-tracked target in the video information, and extracting a motion track of the to-be-tracked target; and controlling a video information acquisition device to perform acquisition view angle adjustment based on the motion trail of the to-be-tracked target. In the embodiment of the invention, the to-be-tracked target can be identified in a complex background, and accurate trajectory tracking of the to-be-tracked target is realized.

Description

technical field [0001] The invention relates to the technical field of video target tracking, in particular to a video target tracking method and device in a complex environment. Background technique [0002] The target tracking technology in the video has gradually matured and gradually applied in various monitoring systems, and in places with relatively simple background or few targets, it can achieve high target tracking accuracy without target tracking drift ; but in a complex environment, and when multiple interfering targets similar to the tracking target may appear at the same time, the video tracking method of the prior art cannot accurately track the specific target, and cannot capture the trajectory of the specific target, resulting in Some video object tracking technologies are not widely used, and cannot meet the needs of users in more scenarios. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prio...
