Online Single Person Tracking For Unmanned Aerial Vehicles: Benchmark And New Baseline

Online tracking a specific person from a low-altitude unmanned aerial vehicle (UAV) is a very interesting and challenging problem to be solved. However, there exists no large-scale aerial video dataset regarding this online single person tracking (OSPT) task. To promote the study of the OSPT problem in UAV, we first construct a new benchmark dataset including 100 fully annotated aerial videos with nearly 130K frames and 11 challenging factors. Second, we evaluate several state-of-the-art online trackers with real-time performance using our dataset, considering the potential applications in the UAV platform. In addition, with respect to the OSPT problem, we attempt to design a new baseline method with the combination of tracking, detection and re-identification and conduct detailed analysis of different components. This method achieves much better performance than the existing online trackers, which will serve as a new baseline for our benchmark.
