| 摘 要： | 结合国家1∶50 000数据库更新工程中影像正射纠正的需要,对于我国较多山区地形复杂、GPS控制点的测量困难地区,利用1∶50 000 DLG中的道路和1∶50 000 DRG数据作为控制资料,通过对控制点选取方式和纠正方法的研究,实现对SPOT 5影像的正射纠正,避免了外业控制点的测量。经过试验,分析其正射纠正精度,... |

| Abstract: | Combined with the requirement of image ortho-rectification in national 1∶ 50 000 database updating project,for the mountainous area which is difficult to survey the GPS control points,using the road data of 1∶ 50 000 DLG and 1∶ 50 000 DRG data as control data,this paper studied the selection method of control points and the rectification method.It realized the ortho-rectification of SPOT 5 image without the measurement of field control points.The experiment shows that the accuracy of ortho-rectification can meet the requirement of orthophoto production in 1∶ 50 000 database updating project. |
| Keywords: | SPOT 5 image ortho-rectification rectification accuracy |
