摘要
介绍了高分辨率遥感卫星影像的RPC模型,重点探讨了基于RPC模型的立体定位算法,并给出了补偿RPC模型系统误差的物方方案和像方方案。针对IKONOS卫星数据的实验结果表明,这些方案能有效地消除RPC模型的系统误差,达到的定位精度能满足110000比例尺的地形图测绘要求。
The paper simply introduces the RPC model of the images from high resolution remote sensing satellites at first, and emphatically discusses the derivation of stereo positioning algorithm based on RPC models, then gives the object space scheme and image space scheme to compensate the systematic error of RPC model. Test results using IKONOS data show that both schemes can reduce the systematic error effectively, and the accuracy achieved can fulfill the requirement to map on scale 1:10 000.
