Lunar DEM Generation by Using Chang'e-1 Three-Line-Array CCD Imagery

摘要

Three-line-array CCD camera was used to obtain images of lunar surface in the first step of China's lunar exploration - Chang'e-1(CE-1), this paper researched the method of lunar DEM generation by CE-1 three-line-array CCD image. We researched the imaging model of CCD image - Collinearity Condition Equations, image matching and DEM generation. And we used some CCD images to validate the algorithms, the result shows that DEM can reflect the change of lunar height.
