摘　　要：介绍了机器人漫游虚拟场景的系统框架,解决了其中的两个关键问题——三维场景建立和碰撞检测.建立三维模型时,基于3dsmax建模渲染后输出3ds文件,利用OpenGL进行三维场景模型的重建;至于碰撞检测问题,是基于包围盒检测技术,根据大型虚拟场景的特点,给出了虚拟漫游系统中碰撞检测的算法.We study the main techniques in Robot virtual browsing,settling two main key techniques such as building of a three-dimensional model and collision detection in virtual browsing.In building of the three-dimensional model,three-dimensional scene in OPENGL is rebuilt by 3ds files which are exported through 3ds max.As to collision detection in virtual scenes,a collision detection algorithm based on bounding box and the new features of virtual browsing is given.

关 键 词：虚拟场景 建模 碰撞检测 漫游
