A kind of method for tracking target of the adaptive piecemeal based on video

The invention discloses a kind of method for tracking target of the adaptive piecemeal based on video, the beneficial effects of the invention are as follows：（1）The method for constructing the tracking target dynamics model more with robustness：Adaptive method of partition is designed, blocked by piecemeal, judgement, adaptively merge the tracked target dynamic model that three steps obtain robust.（2）The weight of image block to be fused is updated under complex environment：During tracking, it is contemplated that influence of the background to To Template, the weight of image block to be fused is updated using improved weighing computation method, to ensure the accuracy of tracking.（3）The preliminary tracking result of moving target is corrected：Preliminary tracking result is corrected by SURF characteristic matchings, improves the tracking accuracy of algorithm.The situation of target occlusion can be handled well, and can is accurately positioned target under the influence of environment, moreover it is possible to adaptively changing tracking window size.
