Terrain Simulation of Lunar Landing Areas Based on Parameterized Shape Models

In this paper, a set of terrain generation algorithm was proposed to simulate lunar terrain in landing areas. Based on characteristic analysis of lunar surface, simulated terrain was constructed by combination of a basic terrain and an impact terrain. According to the algorithm, roadblocks such as screes and craters were modeled through a parameterized method firstly, then the basic terrain was created through random seeds and the impact terrain was generated based on parameterized shape models of roadblocks. Simulation experiments show that terrains generated by the algorithm accord to general features of real lunar terrain, and simulated results can be used to validate lunar road planning algorithm on the ground.
