摘要
针对不利天气条件下交通事故多发问题,分析其对车辆安全的影响,对不利天气下发生的事故进行再现。利用粒子系统对其中的雨雪天气进行实时仿真,运用Open GL雾效果模拟大雾天气,在建立天气仿真系统的基础上还原车辆制动痕迹。最后对一起真实交通事故进行再现。研究结果表明:本系统能为不利天气下发生的交通事故提供逼真、准确的事故处理依据。
According to the problem that lots of traffic accident happened under adverse weather conditions, we analyzed the influence of it on vehicle safety, and researched on the reconstruction of accidents under adverse weather conditions. Using particle system to simulate rain and snow weather in real-time, we applied OpenGL fog effect on foggy weather simulation and reduced vehicle braking trace on the basis of the establishment of weather simulation system. Finally we reconstructed a real accident, and the result turns out that this system can provide accurate and realistic basis of accidents under adverse weather conditions.
