| Abstract: | This paper puts emphasis on the derivation of stereo positioning and block adjustment algorithm based on the RPC models of IKONOS images. According to the systematic error of RPC models in stereo positioning, the object space scheme and image space scheme are provided to compensate it. Test results show that both schemes can reduce the systematic error effectively, and the positioning accuracy is better than 1.3 meters. Block adjustment is the best way for positioning and its accuracy is up to 1.1 meters. |
