Abstract:

Unmanned Aerial Vehicle (UAV) swarm warfare is rapidly developing towards intelligence and practicality, which will pose a huge threat on the future battlefield. Therefore, research on detection and tracking of anti-UAV swarm is imperative. To solve the problems of reduced detection and tracking accuracy caused by mutual occlusion between UAV swarm and weak targets in complex scenes and long-distance detection conditions, this paper proposes a UAVS-Multiple Object Tracking (UAVS-MOT) multi-object continuous robust tracking algorithm. The UAVS-MOT model is based on the multi-branch anchor-free frame prediction structure of the FairMOT model. The coordinate attention module is combined with the DLA-34 network to construct a new backbone feature extraction network, so as to improve the expression ability of feature information. In addition, the new ArcFace Loss function is introduced for training to improve the convergence rate of the model, and the BYTE data association method is used to reduce the target miss rate and improve the track consistency. The experiment shows that the Multiple Object Tracking Accuracy (MOTA) and Identity F1 Score (IDF1) of the proposed algorithm on the UAVSwarm Dataset are 73.4% and 76.1%, respectively, which are 5.7% and 2.9% higher than those of the original FairMOT algorithm. The proposed method can solve the problems of missed and false detection of targets and low tracking accuracy, and has good robustness.
