Imaging Model Based on CE-1 CCD Imagery

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 studied the imaging model of CE-1 CCD image, first analysed the exterior orientation elements of collinearity condition equations were multicollinearity in calculation, and the generalized ridge estimatation was presented. Then Rational Function Model was introduced. At last the experiment was adopt using the CE-1 lunar images. And the result prove that this model can use in lunar photogrammetry.
