稀少控制条件下的SPOT 5 HRS影像定向试验

Experiments on Orientation Accuracy of SPOT 5 HRS Satellite Imagery by Sparse Ground Control Points

通过生产试验,探讨了不同控制点数量及分布下的SPOT 5 HRS影像的定向精度问题,分析了稀少控制点定向后SPOT 5 HRS影像的误差分布情况,为SPOT 5 HRS影像在外业控制点获取困难地区的应用提供了可行方法。

This paper discusses the accuracy instances of the orientation for SPOT 5 HRS imagery by different number of GCPs with different distributions through production experiments,and analyzes the error distribution of SPOT 5 HRS imagery oriented by sparse GCPs.It provides a feasible method for the application of SPOT 5 HRS imagery at the areas where it is difficult to obtain GCPs in field work.
