To cope with the threat to personal privacy and public safety caused by illegal uses of small unmanned aerial vehicles, we propose a closed-loop UAV detection and tracking algorithm suitable for dynamic PTZ camera, which uses the fixed-point cruise mode of high-definition PTZ camera to detect and track unmanned aerial vehicles in the near-earth dynamic complex background, including two modes of detection and tracking. In the detection mode, this paper designs a moving target detection algorithm based on moving background compensation to extract the classification candidate areas, and then uses the lightweight convolutional neural network based on neural network structure search to classify and identify the candidate areas, which can realize UAV detection without reducing the high-definition video image; In the tracking mode, this paper proposes a local search area relocation strategy combined with Kalman filter to improve the tracking algorithm of kernel correlation filter, so that it can still track the target quickly and stably in the servo tracking process of HD PTZ; In order to combine detection mode and tracking mode in a closed-loop framework, this paper also proposes an adaptive detection and tracking switching mechanism based on detection probability and tracking response graph state. Experiments show that the proposed algorithm can be applied to high-definition PTZ cameras in a fixed-point cruise state, and realize real-time accurate detection, recognition and fast tracking of UAV in complex dynamic background near the ground.
