增强现实技术在铁路设备多人协同仿真系统中的应用

Application of Augmented Reality Technology in Multi person Collaborative Simulation System of Railway Equipment

阐述一种基于增强现实技术及HoloLens 2的铁路设备教学培训系统,此系统采用3D Studio Max构建了铁路相关设备的场景模型,采用Unity3D作为三维图形引擎,实现了道岔转辙机等铁路设备的工作原理、故障检修与排除等方面的实训功能,系统支持对同一目标对象的多人协同交互。探讨系统的总体结构、场景模型定位、多人协同交互方案。实践证明,该系统画面流畅、交互性好、模型定位精确,培训效果良好。

This paper describes a railway equipment teaching and training system based on augmented reality technology and HoloLens 2.This system uses 3D Studio Max to build the scene model of railway related equipment.Unity3D is used as the 3D graphics engine to realize the training functions of working principles,troubleshooting and elimination of railway equipment such as switch machines.The system supports the collaborative interaction of multiple people for the same target object.It discusses the overall structure of the system,the positioning of the scene model,and the multi person collaborative interaction scheme.Practice has proved that the system has smooth picture,good interaction,accurate model positioning and good training effect.
