Small target location algorithm based on optimized template matching

Abstract At present, few published template matching algorithms can achieve the performance of commercial software. This paper studies and optimizes existing geometric feature algorithm, combines it with improved Fourier Merlin transform registration finally obtains a fast small target location algorithm. The time algorithm is 1-4ms, its positioning accuracy sub-pixel level, angle less than 1 °, has good robustness to illumination. experimental data show that meets requirements real-time accurate industrial automation production.
