| Abstract: | In this paper,the stereo location method of GeoEye-1 stereopair using rational function model was analyzed and experiment was carried out by using stereopair of Hobart area,Australia.The results show that plane accuracy of GeoEye-1 stereo image pair is better than 3m(CE90) and height accuracy 10.1m(LE90);in case with high accurate ground control points the plane and elevation accuracy of GeoEye-1 stereopair are better than RMSE 0.5m and meet the accuracy requirements of 1∶5000 topographic map. |
