摘 要: | 使用了一种基于SURF的图像匹配方法,使用RANSAC算法来估算两幅图像之间的仿射矩阵,并且通过匹配算法的优化以及设置合适的RANSAC阈值来得到更精确的矩阵,经过验证,本方法简单可靠,误差也控制在一定的范围内。

Estimating Affine Transformation Matrix between Two Images Based on SURF |
| |
Abstract: | We propose an image matching algorithm based on SURF and a following,RANSAC transforma-tion matrix estimation procedure between two images to effectively decrease the estimation error. Further-more,more accurate transformation matrix can be estimated through carefully selecting RANSAC threshold and choosing correct matching algorithm under reasonable circumstances. Empirical tests have demonstra-ted the effectiveness of the devised algorithm by calculating the estimation deviation. |
