摘要:
 给出了一种用虚拟环境下的OBB碰撞检测算法对真实环境下城市道路交通事故进行检测的方法。该方法的主要思想是利用OBB算法计算车辆的包围盒，通过对包围盒的地面平面投影得到车辆矩形二维包围盒，然后检测这些矩形在同一平面上是否相交从而判断车辆是否发生碰撞，最后根据车辆的碰撞方式确认事故的类型，从而完成事故检测。为了提高算法效率，还给出了OBB包围盒数量的控制方法。实验结果表明，该方法能够快速地检测到交通事故的发生。
Abstract:
 Propose a method of testing the urban road traffic accidents in real environment using the OBB collision detection algorithm in virtual environment. The main idea is to calculate the bounding box of vehicles with OBB algorithm,and to obtain the two-dimensional rectangular bounding box of vehicles with planar projection of the bounding box,then to judge whether the vehicles collide each other by detecting whether the rectangular on the same plane,and according the collision mode,the type of accident is recognized,finishing the ac-cident detection. In order to improve algorithm efficiency,the method of control is also provided for OBB amount. Experimental result in-dicates that the proposed method can rapidly detect accidents.
