虚拟现实的公路BIM感知与工程评价方法研究

Research on Highway BIM Perception and Engineering Evaluation Based on Virtual Reality

虚拟现实为公路建筑信息建模(BIM)从二维到三维的感知和协同提供新的手段。论文分析公路工程特征和交通参与者出行体验的现实需求,研究虚拟驾驶、虚拟飞行、虚拟骑行、虚拟步行、增强现实等公路BIM感知与工程评价方法,结合不同交通参与者对工程评价的具体需求,开展以人为本的公路BIM感知、工程评价、协同工作和设计优化。实验结果表明,虚拟现实的公路BIM感知与工程评价连通了BIM模型与人的感知,有助于实现更高的沟通效率和质量。

Virtual reality technology is a new way for the highway BIM to upgrade from 2D to 3D.Based on the analysis of the characteristics of highway engineering and the travel needs of traffic participants,five methods are proposed to perceive highway BIM and evaluate the engineering design results of different road users,including virtual driving,virtual flight,virtual riding,virtual walking and augmented reality.These methods provide technical and tool support for the people-oriented road BIM perception,engineering evaluation,collaborative work,and design optimization.The experiment tests show that virtual reality connects the BIM models with human perception,achieves a higher communication efficiency and quality.
