| 摘要: |
| 在现代卫星摄影测量中，由多颗小卫星组成的卫星编队具有比单颗卫星更优越的性能，能提供更高的空间分辨率和时间分辨率。卫星编队拍摄的序列图像可组成多轨道区域网，通过区域网光束法平差解算就可以获得目标点坐标。介绍了几种适于卫星摄影测量的卫星编队，讨论了影响卫星摄影测量精度的几个因素，给出了仿真实验结果，所得结论可为发展基于卫星编队的摄影测量提供参考。 |

| Abstract: |
| In modern satellite photogrammetry, clusters of low-performancesatellite flying in formation may provide enhanced performance over singlehigh-performance satellite. This is especially true for photogrammetry based on the satellite formation where stereographic imaging may provide higherresolution data. A block is formed by the image sequence acquired with the satellite formation, and the block aerotriangulation by bundlemethod is applied to get coordinateof ground point. Some satellite formation suit for satellitephotogrammetry is introduced and the factors which effect accuracy ofsatellitephotogrammetry is described. The experimental result is given, which would be useful for the development of satellite photogrammetry based the satellite formation. |
