浅析城市轨道交通领域的XR技术应用及前景

Analysis of the Application and Prospect of XR Technology in Urban Rail Transit

摘要: 城市轨道交通作为一种大型、高技术密集型系统，复杂性随其规模的扩大而快速增长，员工培训、线网协同生产、乘客服务等需求不断增加，且要求愈发严苛。扩展现实技术(XR)是虚拟现实(VR)、混合现实(MR)和增强现实(AR)技术的总称，其沉浸性、交互性等优势，能够帮助城市轨道交通各工种从业人员更好地了解实际生产设备与现场，熟悉生产作业流程，感受生产协作机理。本文通过介绍扩展现实技术的基本概念、技术手段，探索其在城市轨道交通领域的应用，助力智慧城市轨道交通建设与发展。

Abstract: As a system with large-scale and intensive high-tech, the complexity of urban rail transit grows rapidly with the expansion of its scale. The demands of employee training, co-production of line and network, and passenger service increase, while the corresponding requirements are getting more severe. Extended reality technology (XR) is the general term of virtual reality (VR), mixed reality (MR), and augmented reality (AR) technologies. With its advantages of immersion and in-teraction, XR can help people in various fields of the urban rail transit to better understand the actual production equipment and site, get familiar with the production process, and perceive the production cooperation mechanism. In this paper, the technological application in the field of ur-ban rail transit is investigated to facilitate the construction and development of smart urban rail transit, with discussions on basic concepts and technological means.
