  • A four-element relaxation matching algorithm based on known initial matching pairs was proposed. The algorithm with characteristics of anti-rotation and anti-scale of rotating angle of vectors was applied as the optimization criterion of matching pairs. Under the condition of higher initial error matching rate and larger walk errors, the algorithm achieved the matching correctly. The value difference of the rotating angle of vectors was calculated, and the optimal matching pairs was selected by using of the support function and the rules of rejection. Experimental results with large images show that the matching speed and correctness of the algorithm is better than Sangnong relaxation matching algorithm.
