摘要
为了给技术人员提供更加便捷直观的工具,提升高速铁路设备管理的层次,为了让公众更加了解高速列车车体各部分组件的结构和功能,提出一种新的认知手段—高速列车虚拟现实系统。系统以高速列车为原型,运用3Ds Max进行建模,在此基础上运用国产虚拟现实软件进行虚拟现实系统开发。由于所建三维高速列车模型大且复杂,首先将三维模型进行简化处理,之后再导入VRP中继续进行系统设计。介绍了LOD算法进行模型简化处理的原理,编制了相关算法对模型进行简化。所设计的这种系统,不但能够使公众身临其境般的体验乘坐动车带来的方便、舒适、快捷,而且能够让管理技术人员快速掌握高速列车的维修、检修技术,从而减少实际装备维修检修培训过程的成本。
In order to provide more convenient and intuitive tools and enhance the level of high-speed railway e- quipment for managerial and technical staffs, this paper proposed a new method of cognition- based on the 3Ds Max and VRP platform design and implementation of virtual high speed train to allow more users to better understand the structures and functions of parts of body of the high speed train. This system choosed high-speed train as the proto- type. Based on the 3Ds Max model, we developed the virtual reality system using the domestic virtual reality soft- ware. Due to the large and complex model of 3d high-speed train, firstly the 3d model shoud be simplified, then the system design was continued after importing VRP. The principle of simplified modeling was introduced, which makes use of LOD algorithm and draws up some related algorithm which can simplify the model. The design of the system, can not only make the public in the experience of a moving ear which brings convenient, comfortable and shortcut, but also make management and technical personnel quickly master the repair, maintenance technology of high-speed train, so as to reduce the costs of actual equipment training process of maintenance overhaul.
