摘要
针对RANSAC方法在剔除SIFT误匹配点方面的不足,提出了一种基于主方向的SIFT误匹配点剔除方法。结果表明,该算法与RANSAC相比,耗时较少,剔除效果更好,保留的正确匹配点数更多,且当误匹配点数量多于正确匹配点时也能得到很好的剔除效果。
In view of the shortcomings of RANSAC in eliminating SIFT mismatches, a method of eliminating SIFT mismatches based on main direction was proposed in this paper. The experimental results have verified that compared with RANSAC the method based on main direction is faster. And it can keep more correct matching points and eliminate more mismatches at the same time. What is more, this method can still obtain good ef ect even when the number of correct matching points is less than mismatches.
