摘　　要：针对基于点特征和线特征配准SAR图像和光学图像的不足,提出了一种基于闭合区域特征的自动配准方法。通过对SAR图像和光学图像进行图像分割提取闭合区域,利用仿射不变矩对闭合区域进行匹配,提取经配对闭合区域的质心作为同名点,实现了高分辨率SAR图像和光学图像配准,取得了较好的配准结果。An automatic registration method based on closed regions features is proposed to aim at solving the deficiency in matching SAR images and optical images based on point features and line features.According to this method,the SAR image and optical image are segmented to extract a closed region and then the affine invariant moment is employed to match the region to extract the centroid of the closed region as the point of the same name,realizing the registration of high-resolution SAR images and optical images and obtaining better registration results.
