[0090] In order to further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the specific implementation, structural features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0091] like figure 1 The flow chart of the anti-occlusion target tracking method based on particle filter and weighted Surf is shown, and the specific steps are as follows:
[0092] Step 1, target template initialization.
[0093] Take the area where the target is located in the first frame as the initial target template, extract the Surf feature points of the target template, and establish the color-weighted histogram p(x)={p u (x)} u=1Lm ;
[0094] p u ( x ) = C h Σ i = ...
