【摘要】：近年来,雨雪天气与夜间行驶引发的道路交通安全问题愈发为人们所重视,车辆在雨雪等特殊运行环境下,制动性能和可见度降低是导致交通事故的主要原因。如何再现事故发生时车辆所处的特殊运行环境是本文研究的重点。而粒子系统和灯光系统对汽车特殊运行环境中雨雪粒子的无规律性、动态性和夜晚条件有良好的模拟效果,在此基础上创建了车辆特殊运行环境虚拟现实演示平台,主要包含以下几方面内容:(1)分析比较了3DMAX软件建模方法的主要特征和适用范围,详尽的描述了车辆模型的建模过程、OpenGL读取环境的搭建以及读取3DS格式的规则,最后在VC++可视化窗口中重绘车辆模型。(2)研究事故现场的基本组成部分道路、植被、房屋和雨雪粒子的建模方法,并对道路、植被、房屋进行了简单建模。详尽分析了雨雪粒子的属性并创建了雨雪粒子模型。然后结合OpenGL纹理融合实现雨雪天气的模拟。最后分析了夜间灯光系统的建模和驱动。(3)研究车辆特殊运行环境三维演示平台的实现。对其中的数据库模块进行了深入研究并设计了车辆特殊运行环境演示模块,最后使用该平台对一起交通事故的雨雪环境进行了再现。
[Abstract]:In recent years, traffic safety problems caused by rain and snow and night driving are becoming more and more important. Under special operating environment such as rain and snow, braking performance and visibility decrease are the main causes of traffic accidents. How to reproduce the special operating environment of vehicles in the event of accident is the focus of this paper. The system and lighting system have a good simulation effect on the irregular, dynamic and night conditions of the rain and snow particles in the special operating environment of the automobile. On this basis, a virtual reality demonstration platform for vehicle special operation environment is created. The main features are as follows: (1) the main features and application of the 3DMAX software modeling method are analyzed and compared. A detailed description of the modeling process of the vehicle model, the construction of the OpenGL reading environment and the rules for reading the 3DS format, and the redrawing of the vehicle model in the VC++ visualization window. (2) the modeling of the basic components of the accident scene, the modeling method of vegetation, housing and rain and snow particles, and the simple construction of roads, vegetation and houses. The properties of the rain and snow particles are analyzed in detail and the model of rain and snow particles is created. Then the rain and snow weather simulation is realized with OpenGL texture fusion. Finally, the modeling and driving of the night lighting system are analyzed. (3) the realization of the three-dimensional demonstration platform of the vehicle special operation environment is studied. The database module is deeply studied and designed. The demonstration module of vehicle special operation environment is used. Finally, the platform is used to reconstruct the rain and snow environment of a traffic accident.
