Abstract: A detecting algorithm of moving target based on the combination between multiple frame energy accumulation and a stabilization method which is combined between improved feature matching algorithm and global motion compensation according to the moving target detection in the aerial video under complex background was proposed.Firstly,it uses the matching method of local area to increase the processing speed of the algorithm,and avoids the influence of the moving target on the background compensation.Secondly,it gets the matching points using the scale-invariant SURF algorithm in combination with the fast approximate nearest neighbor search method,and screens the superior matching points with bilateral matching and k-nearest Neighbor algorithm.Thirdly,it builds the affine transformation model,solves the motion parameters,and makes motion compensation.Finally,it detects moving target through multiple frame difference accumulation.The simulation results show that the method has good effect on moving target detection.
