“嫦娥一号”工程的立体测绘能力评估

Analysis on Stereo Mapping Capability of Chang＇e - 1 Lunar Satellite

本文利用摄影测量的方法，按照“嫦娥一号”卫星工程的设计指标，在摄影测量坐标系内，对“嫦娥一号”立体影像测绘能力进行评估。评估表明：“嫦娥一号”卫星影像可测制等高距为300米的等高线，某些地区也可以采用200米等高距；可以完成摄影测量坐标系内月球外方位元素重建及数字高程模型和正射影像的制作。

The stereo mapping capability of lunar satellite Chang＇e - 1 is analyzed in photogrammetric coordinate system in terms of the design standards for the lunar probe Chang＇e - 1. The results show that Chang＇e - 1 imagery can be used for mapping 300 - meter - interval contour lines, and 200 - meter - interval contour lines in some areas, and be used for regenerating lunar elements of exterior orientation and creating digital elevation models as well as orthoimages.
