Research on Target Tracking Algorithm Based on Three-dimensional Array Laser Imaging System
It is difficult for existing RGB target tracking algorithms to effectively cope with illumination changing and target occlu-sion,a sensing occlusion correlation particle filter target tracking algorithm based on three dimensional array laser imaging system is proposed.Firstly,the target occlusion judging mechanism based on depth information and histogram of oriented gradient(HOG)fea-ture is presented.Then,the correlation maximum likelihood estimation particle filter algorithm is fused to form the target prediction-tracking-calibration-redetection tracking mechanism.Experimental results show that compared with existing tracking algorithms,the sensing occlusion correlation particle filter target tracking algorithm based on three dimensional array laser imaging system can well detect the target occlusion and target tracking,reduce the impact of illumination changing,and it has the advantages of the less calcu-lation and better real-time performance in the target prediction-tracking-calibration-redetection,with a accuracy of 85.7％.
