碰撞检测在交通事故模拟再现系统中的应用

碰撞检测是交通事故模拟再现系统的一个重要部分。该文介绍了OBB包围盒的计算、层次树的建立及相交测试,并将其应用到交通事故模拟再现系统中。实验证明,OBB碰撞检测算法有计算量小、速度快、准确性高等优点,解决了交通事故模拟再现系统中碰撞检测的实时问题。

Collision detection is an important part of traffic reconstruction system. This paper introduces the OBB bounding box calculation, the level tree establishment, the intersection test, and then applys it to the traffic simulation and reconstruction system. Experiments prove that the OBB collision detection algorithm has small computation, fast running , high accuracy advantages and it can solve the real-time collision detection problems in the traffic simulation and reconstruction system .
