基于自动匹配的高分辨率遥感影像校正方法

Method of correction of high-resolution images based on automatic matching

介绍了采用人工选点与计算机自动匹配选点相结合获取一定数量的地面控制点的方法,该方法满足了Thin plate spline校正模型校正的要求,解决了一些高分辨率遥感数据无法用传感器物理模型进行校正的问题。试验证明:在山区采用该方法比常规多项式校正更快捷而且校正效果更好,并具有很好的可操作性和实用性。

This paper approach a new correction process for some High-resolution remote sensing images which can＇t use conventional Physical model to correct directly. This correction method is in the basis Thin Plate Spline correction model. Numbers of ground control points are collected by manually and computer automatically. It is proved that this correction process is good than polynomial functions correction model in time and precision. Furthermore, this correction process is easy to do.
