Abstract
Abstract– –In this paper, a collaborative relay tracking method based on information fusion is proposed for UAVs. Target matching is performed by combining the target's spatio-temporal information with its appearance and other auxiliary cues. Only the motion information and a compressed image of the target are used for target handover. Specifically, to determine the spatio-temporal transfer probability of the target after entering the blind area of visual field, this paper proposes a spatio-temporal correlation model construction method to predict the spatio-temporal similarity. Besides, Siam-LGNet is proposed in this paper for target appearance matching to overcome the effects of various view angles, rotations, scale changes and other factors on the images. This effectively ensures the accuracy of target matching and lowers the model complexity. Additionally, similarities obtained from multiple cues are fused by D-S evidence theory to compensate for the uncertainty of single cue. Finally, the effectiveness of the proposed method is verified in simulation experiments and physical experiments. This paper fills a gap in the field of UAVs relay tracking. The proposed scheme is scalable and lays the foundation for subsequent research on UAVs relay tracking problems.
