Abstract

The invention discloses a video multi-target tracking method and device. The method includes: performing motion detection on the current video frame, and using the detected possible moving objects as observation results; performing data association between the observation results and target prediction results, wherein The prediction result is obtained by at least using the trajectory of the target in the previous video frame for prediction; track management is performed on uncorrelated observation results and prediction results. Obtain new trajectories from the associated observation results; perform trajectory association on the end trajectories and new trajectories; perform trajectory fusion on the associated end trajectories and new trajectories; delete unassociated end trajectories that meet the preset conditions. Through the above manner, the present invention can improve the accuracy of target tracking.

Description

Technical field [0001] The invention relates to the field of target tracking, in particular to a video multi-target tracking method and device. Background technique [0002] Online target tracking is a hot research topic in computer vision. It is of great significance for high-level vision research such as action recognition, behavior analysis, and scene understanding, and has a wide range of applications in video surveillance, intelligent robots, human-computer interaction and other fields prospect. [0003] In complex scenes, due to the influence of factors such as the deformation of the target itself, the mutual occlusion between the targets, or the occlusion of the background still life on the target, especially when the target is occluded for a long time or the target trajectory is not updated for a long time, the target trajectory will be broken Phenomenon, reducing the accuracy of target tracking. Summary of the invention [0004] The technical problem mainly solved by the ...
