Anti-shielding unmanned aerial vehicle target tracking method

The invention discloses an anti-shielding unmanned aerial vehicle target tracking method, which comprises the following steps of: (1) acquiring a video stream through an airborne camera, and manually selecting a bounding box of a target object to be tracked; (2) carrying out feature extraction of an HOG direction gradient histogram, a CN color histogram and an LBP local binary pattern on the image in the bounding box of the selected target object; (3) respectively carrying out filtering operation on HOG, CN and LBP feature vectors; calculating response values under HOG, CN and LBP features; calculating average peak energy under HOG, CN and LBP characteristics; (4) calculating weights under HOG, CN and LBP features through the average peak correlation energy under each feature; solving a response diagram after fusion; (5) calculating the fused average correlation energy; (6) constructing a target anti-shielding strategy and a target matching strategy; according to the invention, when the target is shielded or
