A Real-Time Tracking Method for Satellite Video Based on Long-Term Tracking Framework

Tracking accuracy and frame rate are the two most important indexes of satellite video tracking. Now, the research of close-range tracking algorithm is gradually developing from short-term to long-term, and has been widely used. This paper refers to the idea of long-term tracking strategy and introduces it into satellite video target tracking. With a variety of features as precision guarantee, the redetection function is added to the tracker to ensure the robust tracking. At the same time, the feature dimension is properly reduced. The validity of the algorithm is verified by the video sequence obtained from Skybox-1 satellite. The results show that the tracking effect is good, and the performance of the dimension-reduced version has no significant decrease, and the frame rate is improved by 37.8%. It shows the high feasibility and wide application prospect of long-term tracking strategy in space-based video tracking.
