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
