【摘要】 VR(Virtual Reality)是人们借助电路中肉眼看不见的电子活动,把人们的想象力和思想变成另一种境界的仿真,创建一个虚拟世界或虚拟环境,通过视、听、触觉等作用于人,使人产生身临其境的感受。可以说,想象力和高新技术的结合是产生VR的基础。VR技术的基本特征是沉浸感、交互性和构想,以计算机技术为核心,生成视觉、听觉、触觉等为一体化的虚拟环境,且能使人、机和虚拟环境间进行动态交互。 本文以虚拟现实技术和隧道紧急事件检测方法为基础,研究了隧道视景仿真系统。首先介绍公路隧道交通诱导与控制策略,然后介绍虚拟现实的理论与技术,最后进行了公路隧道紧急事件处理系统的视景仿真的研究和探索。论文将虚拟现实技术应用到公路隧道紧急事件处理系统,为公路隧道紧急事件检测与处理系统的研究开辟一条新路。 该系统应用先进的虚拟现实工具MultiGen Creator和Vega工具,进行隧道紧急事件处理系统的场景再现,具有可控性、安全性、可重复性、经济性等特点,具有一定的实用价值。更多还原

【Abstract】 VR(Virtual Reality), it turns people’s imagination and thoughts into simulation of another kind of realm, establishing one virtual world or virtual environment and making people produce the impression on the spot in person by vision, hearing and feeling acting them. We can say that the combination of imagination and high and new-technology is foundation of producing VR. The basic characters of VR technology are immersion, interaction and imagination. It regards computer technology as the core, creating virtual environment integrating vision, hearing and feeling, making human, machine and environment interact dynamically.This paper studied the vision simulation system of the tunnel based on virtual reality technology and tunnel emergency detection methods. Highway tunnel traffic inducement and controlling strategies are introduced at first. Then, it introduces virtual reality theory and technology. Vision simulation of highway tunnel emergency processing system is studied and explored finally. The thesis applies virtual reality technology to the tunnel emergency processing system of the highway, opening up a new way for the research of processing system and runnel emergency detection of the highway.The system uses advanced virtual reality tool of MultiGen Creator/Vega, reproducing scene of tunnel emergency processing system, having characteristics, such as controllability, security, repeatability and economy, etc. It has certain practical value.更多还原
