| 摘 要： | 针对复杂图像的快速匹配,提出基于Shi -Tomasi角点检测的特征匹配算法.依据图像的角点特征、图像灰度和位置信息,采用最大互相关函数进行相似度计算和粗匹配,用随机样本一致性算法对匹配点对进行校正并消除错误匹配.将该算法应用于实景照片拼接,实验结果表明,对存在较大色差和形变的图像,其匹配精度为97％左右,匹配精度和速度均优于传统匹配算法.

| Abstract: | In view of the fast image registration of complicated images,a matching algorithm based on Shi-Tomasi corner detection is described.The max correlation function is used for similarity computation and rough matching according to the corner features,image gray and location information of the images.Random sample consensus method is used for revising matching points and removing false matching.The algorithm is applied to real photo stitching.Experimental results show that the matching accuracy of this algorith... |
