Abstract

The dense maneuvering individual tracking in cluster target tracking tasks has the problems of difficult cataloging,high computational resource requirements,and complex trajectory modeling.Based on the analysis and differentiation of the motion characteristics and tracking points of dense multi-target and cluster targets,a cluster target tracking strategy based on the fusion planning of individual targets and group evolution features is proposed.By modeling the group structure and number,combined with the dynamic evolution of the group structure,the group is clustered,planned,and classified.On this basis,the shape,center,number of targets,as well as the grayscale,position and other feature information of individual targets are fused and calculated to achieve robust extraction of the tracking position of cluster targets,improve the stable tracking ability and accurate trajectory generation ability of the cluster.It mainly solves the clustering problem of group targets,the location extraction of group envelope,the location fusion problem of multiple single targets,the position switching strategy and the smooth transition problem of tracking between multiple groups or group beyond the field of view.The experimental results verify that the proposed method can effectively improve the tracking performance,the tracking accuracy is increased by 12%,the tracking stability is increased by 4 times,and the calculation amount is reduced.

Key words： Cluster; track; Integration; Group envelope; Group structure; Tracking accuracy; Tracking stability
