Study on 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 studies the imaging model of CE-1 CCD image, first analyses the exterior orientation elements of collinearity condition equations are multicollinearity in calculation. Then, the generalized ridge estimatation is presented. At last the parameters of generalized ridge estimatation is explained. And experiments prove that this method is very simple, steady and effective.
