摘要： 针对基于模板灰度相似性测度的匹配方法抗旋转性差的缺陷,依据真实匹配角点与邻域内其他角点位置关系存在拓扑不变性,提出了一种基于尺度、距离、旋转测度的角点匹配方法.该方法首先利用相位相关法对角点进行初始匹配,而后对每对候选匹配角点进行基于尺度、距离、旋转测度的计算,利用计算后的测度函数值来判断初始匹配是否为正确匹配.实验验证了提出的角点匹配方法的匹配结果要明显好于直接基于模板灰度相似性测度的匹配方法.

Abstract: Because there is a topological invariance of location between true corner to be matched with other corners in neighborhood, a new corner matching algorithm based on measures of scale, distance and rotation is proposed to solve the drawbacks of conventional matching algorithms based on the similarity measure of gray levels. In this algorithm the corners are matched initially according to the phase-correlation, and every couple of corners to be matched is computed according to the measures of scale, distance and rotation. Then, whether a match is right or wrong is judged by the measure function values given by the computation. Some experimental results verified that the matching algorithm proposed is better than other conventional algorithms for matching corners.
