| 摘 要： | 针对遥感影像的处理应用中，传统的手工选取控制点速度慢、精度低和强度大等缺点的问题，提出了一种基于影像灰度和影像特征混合自动提取控制点的新方法。在进行控制点的自动提取时，该方法速度快、错误匹配率低、精度高。方法内容包括特征点提取、构造影像金字塔以及基于金字塔数据结构的互相关匹配。

| Abstract: | The enormous increase in the volume of remotely sensed data is acquired by an ever growing number of earth observation satellites means that automation now plays a more vital role than ever before in application of remote sensing. However, traditional method manually selected control point is laborious, tedious and complex task. To speed the selection of control-point, a mixed algorithm on automatic selection of control point is proposed . The main contents include extraction of feature points, generation of pyramid image structure and similarity extent computation based on a pyramid image structure. |
