【摘要】 随着汽车工业和交通运输业的发展,汽车的节能、安全和环保已成为影响人类生存、制约汽车工业发展的三大问题。随着我国经济的发展,开发出一套适合我国的交通事故再现分析系统则具有十分重要的意义。作为交通事故再现分析系统的重要组成部分的车辆运动三维仿真,是根据道路交通事故的事故特征,基于虚拟现实技术的原理最终得以开发,其主要用于演示车辆在道路交通事故中的运动过程,并通过实际案例对三维仿真程序进行了验证。这样不仅可以提高交通事故再现分析系统的适用范围及精度,而且也为正确处理交通事故提供了可靠的理论依据。更多还原

【Abstract】 Road traffic accidents are one of the global social effects of pollution.According to World Health Organization statistics, road traffic accidents occurredabout 55,000,000 in the whole world, there were about 1,270,000 people who losttheir lives in road traffic accidents and 8,000,000 people wounded in 2003. Duringone hundred years, the amount deceased is over 32,000,000 people, which is half ofthat in the Second World War. So road traffic accidents have brought about thehuge loss of life and wealth to the nation and people.For reconstructing accidents, men can make use of measure data of the sceneof an accident, the investigation result of experts, proofs from witnesses or agentsand utilize all kinds of test models to estimate the movement condition of vehiclesbefore and after crash, which is the recurrence of vehicle collision. Reconstructionof collision will be involved in many factors, in which have some conflicts anddisagreements. To draw a logical conclusion, the accident needs analysis again andagain, which will spend more time, and its result will not ideal by manual work.With the development of computer technique, traffic accidents reconstruction willget a kind of efficient means to support.There is a long history of researching accident reconstruction with computertechnique in developed countries. In 1970’s, this research was started in America,Japan, Europe, and so on. At the present, many representational software foranalysis traffic accidents have come up, such as CRASH3、PC-CRASH、EDSMAC、ANALYZER PRO、PAFU、SLAM、IMPAC、EDCAD、JZDACS、WACCAR. In China, there exist a lot of limitations in traffic accidents’analysis, but it’sstill in its infancy now. With the fast development of economy, it becomes moreimportant to open up our own software adapted to analyze China’s vehicleaccidents. In road traffic accident vehicle movement three–dimension reconstructionsystem is developed in this paper based on the direct demand of analytical trafficpeople and experiences of author. The purpose of the system is to help peoplereconstruct the whole precession of traffic accidents, and thereby determine theresponsibilities of both parties and reduce civil disputes. On the basis of system scheme structure, in the paper the main work follows: 1) The paper summarizes the status in quo of research 、recent fruits anddevelopment trend of the road traffic accident reconstruction system, and moreoverunderstands the condition and the need of traffic management dealing with thetraffic accident on the spot, in additional the paper engages in the total design forthe system combined with the extensive practical accident handing experience. 2) The paper deeply analyzed one-dimension and two-dimension problems inroad traffic accident and modified the old movement models of vehicles, whichimproves the precision and applicable rang of road traffic accident reconstructionsystem. 3) On the basis of system scheme, vehicle movement three-dimensionreconstruction system of road traffic accident is developed. The vehicles motionprocess in the whole traffic accident can be demonstrated in a way ofthree-dimension animation. Based on the technique of virtual reality, the tools ofVC、OpenGL and 3DMAX are used . In the virtual world, scene elements and angleof view and others can be easily changed in order to obtain the real scene. 4) The paper utilizes vehicle collision trials to calibrate road traffic accident three-dimension reconstruction system of road traffic accident. The result shows it更多还原
