摘　　要：Sift算法是目前研究较多和应用比较广泛的一种算法,但是目前的研究主要集中于算法中的关键点的获取和关键点的特征描述,而对于关键点的匹配研究较少。结合足迹图像特征,在原有匹配方法的基础上,提出一种加强限制匹配的方法,有效减少关键点的漏配,并提高匹配准确率。Sift-algorithm has been extensively studied and widely used at the present time.However,the current research of this algorithm focuses more on the acquisition as well as feature description of the keypoints other than their match,thus in combination of the features of the footmark and based on the original matching method,this paper proposes another method which can strengthen restriction of the match,effectively reduce the leakage of distribution of the keypoints and greatly improve the matching accuracy.

关 键 词：SIFT算法 图像匹配 关键点 足迹
