| 摘 要： | 对GeoEye-1立体定位模型进行初步研究,给出消除RPC模型系统误差的控制点选择和区域网平差方案。结合PixelGrid进行了基于不同布点方案下区域网平差实验,并和INOKOS定位精度进行对比分析。结果表明,加入少量控制点(1～9个)可明显消除RPC模型系统误差,平面精度达到0.2～0.3m,高程精度达到0.5m,能满足公路勘测选线1∶2000测图要求,高分辨率正射影像和数字地面模型可直接用于公路勘测选线设计。

| Abstract: | s:Stereo positioning model of GeoEye-1 images was studied in this paper and the control point selection strategy and block adjustment scheme is presented to eliminate the system error in RPC model.The block adjustment schemes based on different control point distribution were conducted under the PixelGrid in the experiment and the positioning accuracies were analyzed comparing with INOKOS.Experimental results showed that the systematic errors of RPC model were eliminated apparently after adding a small amou... |
