基于UE4及BIM技术的公路工程电子沙盘构建探析

Discussion on the Construction of Electronic Sand Table of Highway Engineering Based on UE4 and BIM Technology

为解决传统电子沙盘制作的诸多弊端,采用游戏引擎展现效果的技术优势,基于UE4虚幻游戏驱动引擎的电子沙盘制作方法,重点研究制作过程中数据文件空间尺度及坐标系统的对应关系,搭建公路、地形等交通要素的三维场景模型,得到逼真度、沉浸感以及交互性俱佳的公路电子沙盘。该方法有效提升了公路设计的质量和展现效果,在公路设计、交通仿真、驾驶模拟、交通设施及运维管理等方面具有广阔应用前景。

In order to solve disadvantages of traditional electronic sandbox production and adopt technical advantages of game engine in display,this paper focuses on the corresponding relationship of the spatial scale of data files and coordinate system in the production process,builds the three-dimensional scene model of road,terrain and other traffic elements,and obtains the fidelity and heaviness immersion and interactive road electronic sand table,based on the electronic sandbox production method of the UE4 virtual game driving engine.This method effectively improves the quality and effect of highway design,and has broad application prospects in highway design,traffic simulation,driving simulation,traffic facilities and operation and maintenance management.
