摘　　要：介绍了遥感影像多项式几何校正的原理,提出了应用最长距离法筛选地面控制点的思想;详细叙述了应用最长距离法筛选地面控制点的原理、处理流程及方法示例;最后说明了这种方法在实践中的应用.实践证明,应用最长距离法筛选地面控制点,是提高遥感影像多项式几何校正精度的有效途径.Firstly, the paper introduces the theory of remote sensing image multinomial geometric rectifying, presents an idea of applying Longest Distance Method (LDM) to filter Ground Control Points (GCP) from overfull ones in a remote sensing image. Then, the paper recounts the theory of LDM and the flow of it and gives an example of how to apply this method. Lastly, it shows this method applied in practice. Practices prove that applying LDM to filter GCP is to raise the precision of geometric rectifying effectively.
