| 摘 要： | 提出了一种基于Harris角点特征的精确匹配方法。该方法首先提取参考图像及待拼接图像中各自的Harris角点点集,并计算出这2个点集间每对点的圆形邻域图像的相关系数;再通过提取各个角点邻域的Hu矩特征,获得了该特征下每对点的相似程度。将不同特征下的相似度进行归一化并融合,构造出2个点集间,每对点的相似度表。在此表的基础上,优化匹配结果,使得匹配点对的总体相似程度高,从而得到精确匹配。由于Hu矩特征具有旋转及尺度不变性,因此提取出的角点特征能够较好地抵抗常见的图像变换。最后,实现了一套包括图像预处理、图像对齐与匹配等诸多模块的图像拼接系统。通过实际操作表明,该方法的图像拼接效率较高,有较好的鲁棒性。

| Abstract: | In this paper,a refined feature matching approach based on Harris Corners Detection was proposed.This approach first extracts the Harris corner point sets within the referring image and the image to-be-processed.Then,it calculates the correlation between each corner point from both point sets within a circular area around it.After that,it extracts the feature of Hu moment from each point,and attains the similarity.By normalization and fusion of the similarity under different features,the similarity table is... |
