为使用嫦娥一号三线阵光学影像进行月球测图,本文研究月球测图的特殊性问题及其解决方案,提出基于Cle-mentine卫星影像数据和ULCN2005月球控制网进行月球测图的方法,应用商业数字摄影测量软件和自主研发的辅助软件系统进行了月球测图实验。该实验选择了月球近南极的一块区域(W109.7°~W163.4°,S69.3°~S84.2°,面积约1.5×105km2),采用10个轨道的60景Clementine的UVVIS影像、408个ULCN2005控制点(其中56个作为检查点)和1337个连接点,建立该区的DTM和地形图,水平中误差和垂直中误差分别为98.639m(0.19pixel)和1003.751m(1.93pixel)。论证基于嫦娥数据生成月球DTM和地形图的可行性。
A pilot project using Clementine imagery to create a DTM and topographic map of a portion of the southern polar region of the Moon is presented.This region covers W109.7°~W163.4°,S69.3°~S84.2° of the Moon,with the area about 0.15 million km2.The DTM was constructed from 60 Clementine UVVIS images from 10 orbits,408 ULCN2005 points among which 56 were check points,and 1337 tie points.The planimetric and vertical resulting RMS error of the control points were 98.639 m(0.19 pixel)and 1003.751 m(1.93 pixel).The...
