| 英文摘要 |
| The interested targets in UAV (unmanned aerial vehicles) aerial image sequences are always small in size,
and have significant changes in appearance when coupled with a lot of background noises, making the target detection
and tracking a very difficult task. To solve these problems, this paper presents a method to autonomously detect and
track multiple maneuvering targets in UAV aerial image sequences. Firstly, image features of the targets are extracted
and classified through cascade classification algorithms to obtain the strong classifier of the targets; then, the targets can
be autonomously detected by using the classifier. The detection results are associated and filtered through global optimal
association algorithms to achieve the purpose of tracking and recognition of multiple maneuvering targets. The optimal
association-cost matrix is simultaneously fused with distance and direction information which can improve the tracking
robustness. Using the ground tanks in UAV aerial image sequences as the interested targets, the experimental results
showed that the proposed method can autonomous detect and track multiple maneuvering targets with desired tracking
robustness. |
