【摘要】:近年來,雨雪天氣與夜間行駛引發(fā)的道路交通安全問題愈發(fā)為人們所重視,車輛在雨雪等特殊運(yùn)行環(huán)境下,制動(dòng)性能和可見度降低是導(dǎo)致交通事故的主要原因。如何再現(xiàn)事故發(fā)生時(shí)車輛所處的特殊運(yùn)行環(huán)境是本文研究的重點(diǎn)。而粒子系統(tǒng)和燈光系統(tǒng)對(duì)汽車特殊運(yùn)行環(huán)境中雨雪粒子的無規(guī)律性、動(dòng)態(tài)性和夜晚?xiàng)l件有良好的模擬效果,在此基礎(chǔ)上創(chuàng)建了車輛特殊運(yùn)行環(huán)境虛擬現(xiàn)實(shí)演示平臺(tái),主要包含以下幾方面內(nèi)容:(1)分析比較了3DMAX軟件建模方法的主要特征和適用范圍,詳盡的描述了車輛模型的建模過程、OpenGL讀取環(huán)境的搭建以及讀取3DS格式的規(guī)則,最后在VC++可視化窗口中重繪車輛模型。(2)研究事故現(xiàn)場的基本組成部分道路、植被、房屋和雨雪粒子的建模方法,并對(duì)道路、植被、房屋進(jìn)行了簡單建模。詳盡分析了雨雪粒子的屬性并創(chuàng)建了雨雪粒子模型。然后結(jié)合OpenGL紋理融合實(shí)現(xiàn)雨雪天氣的模擬。最后分析了夜間燈光系統(tǒng)的建模和驅(qū)動(dòng)。(3)研究車輛特殊運(yùn)行環(huán)境三維演示平臺(tái)的實(shí)現(xiàn)。對(duì)其中的數(shù)據(jù)庫模塊進(jìn)行了深入研究并設(shè)計(jì)了車輛特殊運(yùn)行環(huán)境演示模塊,最后使用該平臺(tái)對(duì)一起交通事故的雨雪環(huán)境進(jìn)行了再現(xiàn)。
[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.
