3D Simulation Model of Lunar Crater Based on Single CCD Image

摘要

The paper gives an algorithm to simulate the crater topography from a single Charge Couple Device image. Refer to the Oren-Nayar reflectance model, several parameters of the lunar crater and constraint conditions have been added to this new algorithm, also the small craters have been enhanced in the frequency domain. Comparing with the Tsai's Shape from shading algorithm and the other new SFS algorithm, the simulation results of the new algorithm have shown more details of craters topography.
