摘要
介绍高分辨率卫星影像RPC模型的定义及其解算方法,推导RPC模型立体定位的基本方程,在此基础上对RPC模型的区域网平差进行深入研究。IKONOS卫星数据的实验结果表明,RPC模型误差呈现较强的系统性,但通过物方或像方的补偿立体定位可达到优于1.3 M的定位精度,区域网平差是最优的定位方法,精度可达1.1 M。
The Definition and the solution of the RPC model used by images from high-resolution satellite are simply introduced at first, and then the basic equations of stereo positioning are derived, based on which a comprehensive study of the block adjustment algorithm of RPC models is carried ont. Test results from IKONOS data show that the positioning error in RPC model is systematic, but with the help of compensation in object or image space the precision of stereo positioning is better than 1.3 meters; block adjustment is the best way and the aacuraey is up to 1.1 meters.
