一种遥感影像的自动配准方法
Method of Automatic Registration of Remote Sensing Image
【摘要】 图像配准技术是图像融合、图像镶嵌以及影像三维重建的基础 .提出了一种基于 SUSAN( Smallest U nivalueSegment Assimilating Nucleus)算子的图像配准方法 .利用 SUSAN算子提取两幅图像的角点 ,通过粗匹配和细匹配两个步骤得到匹配角点对 .根据这些角点对对图像配准 .试验表明该方法能有效的实现影像自动配准
【Abstract】 The technique of image matching is the basis of image fusion, image mosaic and scene 3D reconstruction. A novel image registration method based on SUSAN operator is proposed. Firstly, corner points are extracted using SUAN operator. Then matched corner pairs are selected through coarse matching and fine matching. Based on such points pairs, Aerophotos are registered automatically.
