摘　　要：虚拟现实技术的出现为月球漫游车的设计、试验、优化等提供了新的有效手段,构建逼真的虚拟月面是进行该类研究的一个基础。提出了一种真实感虚拟月面建模方法,该方法利用分形技术生成月面基础地形,在此基础地形之上基于两点假设和统计信息添加陨石坑模型和石块,并在外围拼接山坡模型,最后生成效果逼真的参数化、可重用的虚拟月面模型。仿真结果表明该虚拟月面模型满足虚拟现实环境下进行月球车在凹凸不平月面上的运动学、动力学仿真试验的需求。The emergence of Virtual Reality technology provides a new efficient approach for lunar rover designing, testing, optimizing etc. Constructing realistic virtual lunar surface is a base of such researching works. A realistic lunar surface simulation method was provided. It uses the fractal technology to form the base of lunar terrain, adds lunar craters and stones to the terrain according to the real statistical data and two hypothesis, and then joints hill model around it, forming a realistic parameterized reusable virtual lunar surface. The simulation test satisfies the need of lunar rover＇s kinematic and dynamic simulation on uneven terrain in the virtual environment.
