 探讨了基于有理函数模型的GeoEye-1立体定位方法,并使用澳大利亚Hobart地区立体像对进行了有关试验研究,结果表明,GeoEye-1立体影像无地面控制点的平面精度在3.0m之内(CE90),高程精度约为10.1m(LE90);在良好的地面控制点的支持下,平面和高程精度均优于0.5m(RMSE),基本可满足国家1∶5000基本比例尺地形图测图要求。 更多还原

【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. 更多还原
