Target automatic tracking method, system and device for unmanned aerial vehicle platform and medium

The invention belongs to the technical field of computer vision, relates to the field of target tracking, and discloses an automatic target tracking method, system and device for an unmanned aerial vehicle platform and a medium. According to the automatic target tracking method, based on obtained gradient histogram feature matrixes and color naming feature matrixes of an area in a target frame and a preset area outside the target frame, an alternating direction multiplier method is used for iteratively solving and updating a position filter, and the updated position filter is obtained; wherein a gradient histogram feature matrix and a color naming feature matrix of a preset region outside the target frame are used as context background perception regular terms; and on the basis of the obtained multiple frames of images, performing automatic target tracking frame by frame by adopting a feature response confidence fusion strategy considering spatio-temporal information. The technical scheme provided by the inve
