| 摘 要： | 针对在图像匹配中,传统RANSAC算法在特征点提纯方面效率不高的问题,本文采用空间几何约束算法进行特征点提纯,得到初始匹配点集,再通过RANSAC算法进行特征点精确提纯。实验结果表明:该方法在保证较高精度和鲁棒性的前提下,能有效提高RANSAC算法的时间效率,提高图像的拼接精度和速度。

| Abstract: | In the image matching,the efficiency of feature point purification is not high in the traditional RANSAC algorithm,the space geometric constraints algorithm for purification of feature points could get the initial matching points set,then through the RANSAC algorithm achieve accurate purification of feature points.The experimental results show that this method can guarantee higher accuracy and robustness,effectively improve the time efficiency of RANSAC algorithm,and improve the image stitching accuracy and speed. |
