摘要
利用"嫦娥一号"卫星上搭载的CCD立体相机获取的月面三线阵影像数据,再配合激光高度计(LAM)数据,经过摄影测量解算可以制作月面数字高程模型(DEM)和数字正射影像图(DOM)。本文采用两种方法对月球卫星CE-1三线阵影像数据进行了月面点坐标的解算试验,方法一是根据测控给出的外方位元素直接解算,方法二是对影像上提取的像点进行区域网平差解算,根据两种方法的解算结果,比较了各方法的精度,达到了预期目的。
Chang＇e-1 is the first satellite for lunar probe developed by Chinese own effort.By using the CCD stereo camera of the satellite,we can obtain three-line-array imagery of the moon.Related with LAM data and some algorithms in photogrammetry,we generated DEM and DOM of lunar surface.In this paper the author studied two methods of calculating lunar surface points using lunar imagery obtained from satellite Chang＇e-1.One method calculated the coordinates directly according to exterior orientation elements.The other method used block adjustment calculation of image points.By comparing the precision results of the two methods,the expected aim has been now achieved.
