| Abstract: | The geometric positioning accuracy of high-resolution satellite imagery is mainly determined by the precision of image exterior orientation elements.The error propagation rules of the image exterior orientation elements in two typical cases called direct geopositioning for single image and forward intersection for stereo images are analyzed and compared in this paper.The conclusions can provide references for the satellite orbit-attitude control and camera design departments. |
