Abstract :
In this paper, three-line array CCD lunar image DEM generation method is studied. According to the actual characteristics of Chang´E-1 lunar surface images, image matching method based on SIFT and combined with correlation coefficient is designed. Photogrammetric processing is applied to images by selecting appropriate control points using laser altimeter data, DEM is generated by DEM interpolation of mobile surface fitting method. The experimental results show that DEM of certain precision can be obtained by this method, the RMSE of elevation is limited in 3 pixels.
