| 摘 要： | 提出了一种基于角点特征值的角点匹配快速算法,并利用视差梯度约束去除误匹配的结果。首先把提取角点时得到的角点特征值作为匹配的一个约束,提高了基于灰度相关的角点粗匹配运算的速度,然后利用视差梯度约束对粗匹配的结果进行求精运算,去除误匹配的结果,实验结果证明了该算法的有效性。

| Abstract: | In this paper,A fast algorithm is proposed for speeding up the process of corners matching.The proposed algorithm uses gradient of disparity to deal with outliers.Firstly,corners' threshold is used as a constraint when doing corners matching,then outliers are detected by using gradient of disparity constraint.Experimental results demonstrate the effectiveness of the matching method proposed. |
