The invention discloses a cyclic matrix video tracking method with partition. The method comprises a step of dividing a target into a plurality of sub targets with the same size and carrying out cosine window adding preprocessing on each sub target, a step of carrying out cyclic matrix tracking on each sub target respectively to obtain the tracking result of each sub target, and calculating the confidence level of the result, and a step of combining sub target tracking results and confidence levels to obtain the real position of the target. According to the method, the idea of partition is used, the target is subjected to partition processing, each sub target is subjected to cyclic matrix tracking respectively, the spatial distribution information of the target and a background is fully utilized, and the robustness of a video tracking algorithm is raised. According to the method, a complex scene video can be subjected to robust tracking, and the conditions of target scale change, serious blocking, target rapid change, 3D rotation and the like are effectively processed. In addition, the tracking speed is fast, the video processing speed can reach dozens of frames per second, and a real-time requirement is completely satisfied.
