一种基于OBB包围盒算法的交通事故检测方法
A Method of Traffic Accident Detection Based on Oriented Bounding Box Algorithm
摘要
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.关键词
