说明：  首先用 SURF 方法提取特 征点 其次用最近邻匹配法找出对应匹配点对 结合 RANSAC 和最小二乘法求出图像之间的映射关 系 最后利用所求的变换参数插值得到配准后的图像
(First with SURF extracted feature points followed by the nearest neighbor matching method to find the corresponding matching points RANSAC and least squares method combines images obtained using the mapping between the final transformation parameters are asking interpolated image after registration)
