摘　　要：碰撞检测是计算机仿真、虚拟现实等领域内的研究重点之一,其中基于包围盒的碰撞检测算法是一种比较方便有效的方法。为了达到仿真系统中所需要的碰撞检测的精确性和实时性,对方向包围盒(OBB)的计算方法进行了分析,并针对其不足之处进行了改进和优化。利用改进后的OBB包围盒碰撞检测技术实现了JQ900型下导梁架桥机中部件间碰撞的精确快速检测,并最终在VC++和Open Inventor API平台上实现了系统的逼真的仿真效果。Collision detection is one of the research emphases in the field of computer simulation or virtual reality, in which the collision detection algorithm based on bounding box is a more convenient and effective way. An Oriented Bounding Box method of calculation was analyzed in order to achieve desired accuracy and real - time property of collision detection in the simulation system, and it was also improved and optimized. Accurate and rapid collision detection of the parts of JQ900 Overhead Launching Gantry with Lower Launching Nose was realized using improved OBB technology, and finally realistic simulation results of the system based on VC ＋ ＋ and Open Inventor API platform were obtained.
