摘要:

利用多个测区的样本数据和大量的野外实测GPS控制点, 进行“天绘一号”01星立体影像无控制点、不同控制条件下的定位精度检测, 结果表明在无控制点定位时平面精度优于10 m, 高程精度优于6 m, 控制点定向时的检查点平面精度优于9 m, 高程精度优于3 m, 完全满足1:50000比例尺成图精度要求。

Evaluation of the location accuracy of the Mapping Satellite-1 stereo image
Abstract:

This paper did an evaluation of the location accuracy of the Mapping Satellite-1 Three-Line-Array(TLA) image with and without control points. The experiment data involves several test blocks and a lot of fi eld surveyed GPS control points. The result showed that the horizontal accuracy of TLA image can reach 12 m and the height accuracy can reach 10 m without GCPs. When using GCPs, the accuracy can reach eight meters and three meters respectively which can satisfy the accuracy requirement of 1:50000 mapping.
