| 摘 要： | 影像几何纠正是遥感图像处理的重要技术。为了克服现有方法在实际应用中的不足,提出利用控制点影像库进行影像自动匹配,然后进行几何变化的方式。这种方法简单有效,快速稳定,匹配得到的同名点数量足够且分布均匀,并通过引入最小二乘匹配使配准达到子像素精度,提高几何纠正的速度与可靠性。

| Abstract: | Geography correction of images is the important technology of image processing. In order to improve the general method, presents a new method based on database of control point's image, which is simple, fast and stable, can offer enough points that reasonably distribute, high accuracy by the LS mathing. |
