Design of video aerial target detection and tracking system based on AM5728

A detection and tracking system for aerial target in the dynamic background is designed based on AM5728 in this paper. Firstly, a moving target detection algorithm based on LK optical flow and inter-frame difference is proposed. According to the number of FAST feature points, the foreground target is extracted by inter-frame difference, or the matching points are calculated by the LK optical flow algorithm to obtain the registration image, and then the foreground target is extracted by the image difference. The false target is removed by 8-connected components labeling and multi­frame association in order to obtain the target in the current frame. Then, the KCF tracker is initialized by the result of the detection algorithm and tracks the target stably. Finally, target detection and tracking algorithms are transplanted to AM5728. Experiments demonstrate that the video aerial target detection and tracking system can obtain dynamic information of the aerial target in real time and track aerial target stably for a long time under the conditions of scale changes, light changes, etc.
