【摘要】 中国高速铁路的发展日新月异,其安全性要求也越来越高,对于司机驾驶水平的要求也在相应变高,将虚拟现实技术应用到铁路交通领域,创建列车运行视景仿真系统,对于列车运输系统中的驾驶培训、运行监控、甚至是远程调度等方面都具有相当深远的影响。列车视景仿真系统安全、经济、可重复性的特点,对于列车运行系统的发展也是一次质的飞跃。本论文以列车运行环境为研究对象,以Multigen Creator/Vega Prime及VC++为平台,建立了列车运行视景仿真的虚拟场景,定制了列车运行视景仿真系统的实现方法和步骤。本文主要研究内容如下所示：1.深入了解虚拟现实技术在铁路交通领域的应用及实现方法,确定仿真系统的实现方案,对场景模型、仿真环境做总体规划。2.通过三维动画渲染和制作软件3ds Max建立场景及运动对象的初始模型,运用Multigen Creator软件对初始模型进行改造及优化,分析了列车运行视景仿真的建模步骤,并深入讨论了Creator软件的建模技术及优化技术,使视景仿真系统在逼真性和实时性两方面达到平衡。3.通过Vega Prime仿真软件中的Lynx Prime制定了系统的初始框架,大大降低了程序编写的工作量,实现了场景的预览、视点的变换。气候环境模拟功能使列车可在特殊情况下进行运行仿真。用path tool建立多条固定路线,可仿真列车运行在不同路线间的切换。4.在VC++平台下建立列车运行视景仿真系统的人机交互界面,系统的主要实现功能一目了然,为用户节省了熟悉系统的时间。详细介绍了列车在不同路线不同环境下运行的实现方法,创建菜单功能快捷键,提高用户的操作时间。通过OpenGL函数库创建了列车运行信息的实时显示窗口,使用户可以实时控制列车运行速度。更多还原

【Abstract】 As the rapid development of high-speed railway in China, its security requirements are also higher for driver level requirements are higher,the application of virtual reality technology to railway transportation and creating a visual simulation system for train operation have far-reaching consequences for drivers’training, operation monitoring and remote scheduling in the transportation system.Visual simulation of train has characteristics of safety,economic and repeatability,which is a qualitative leap for the development of train operating system.This thesis takes train operation environment as the study objcet, established the virtual scence of train visual simulation based on Multigen Creator/Vega Prime and VC++, and developed implementation methods and procedures of visual simulation system for train operation.The main content of this article is showed as follows:1. Deeply understanding virtual reality technology’s application and realization method in the field of railway transport, determining the implementation of simulation system, on scenario models and simulation environment making overall planning.2. Establishing the initial models of scenes and moving objects through the three dimensional animation rendering and modeling software-3ds Max, transforming and optimizing the initial models using MultiGen Creator software, analyzing the modeling steps of train running visual simulation, and discussing in depth on modeling and optimizing techniques of Creator software. This section makes scene simulation system in both the authenticity and real-time balance.3. Developing the initial famework of the system by Lynx Prime in the simulations software-Vega Prime, which will reduce the workload and the program code writing, and enable preview of the scene, view transform. Climate simulation capabilities enble train runing in exceptional circumstances, establishing various fixed routes with the path tool which prepares for running trains on different routes.4. Establishing the human-computer interaction interface of visual simulation system for train operation under the VC++platform, the system’s main function is easy to understand which saves time for users to be familiar with the system. Detailing the implementation methods for trains running in different environments and routes. Create the menu function keys to improve users’operation time. Creating a real-time display window about train’s running information by using OpenGL library that allows users to control train speed in real time.更多还原
