三维虚拟现实技术结合CAD在铁路选线技术中的应用

Application of 3D virtual reality technology combined with CAD in railway route selection

随着社会的发展和时代的进步,人们日常出行对于铁路的需求越来越强烈。因此需要建设更多的铁路来满足人们的需求。在建设铁路之前,首先要选择铁路建设地址,这是很重要的一点。在铁路选线的过程中需要考虑到很多因素,例如当地的自然资源条件、地质因素、人们的出行习惯以及经济水平等。综合考虑这些因素做出决定后,运用最新研发的虚拟现实技术,对铁路的空间构造模拟出一个三维立体空间场景。在三维虚拟现实技术的基础上,结合CAD设计来进行铁路选线。本文从研究铁路选线的角度出发,进一步分析三维虚拟技术和CAD平面设计在铁路选线过程中的运用,从而建立一个三维虚拟空间场景,能够提高铁路选线的效率和精确度。

With the development of society and the progress of the times, people＇s daily travel demand for railway is more and more intense. It is necessary to build more railways to meet people＇s needs. In the construction of the railway, we must first choose the railway construction address, which is very important. Many factors need to be taken into account in the process of railway route selection, such as local natural resources, geological factors, people＇s travel habits and economic level. Taking into account these factors, we make use of the latest research and development of virtual reality technology to simulate the spatial structure of the railway. On the basis of 3D virtual reality technology, combined with the CAD design, the railway route selection. This paper studies the railway line selection point of view, further analysis using 3D virtual technology and CAD graphic design in the railway line selection process, so as to establish a three-dimen- sional virtual space scene, can improve the efficiency and accuracy of the railway line selection.
