摘　　要：为提高用于道路交通仿真三维场景的建模效率,提出基于LandXML数据可视化技术的场景生成方法,定义了用于道路交通仿真的相关数据格式,设计了数据转化算法,实现工程设计数据向虚拟三维仿真图形数据自动化转化,并基于图形渲染引擎OGRE开发出场景编辑工具。使用效果表明:此方法有利于提高建模速度和精度,与工程设计数据建立的接口可使其设计成果在道路交通仿真中得以直接利用。To improve the efficiency of modeling three-dimensional scene for road traffic simulation, this article proposed scene generation method based on the LandXML data visualization technology, defined relevant data format of Road Traffic Simulation, designed data conversion algorithms to realize the automated conversion from road design data to Virtual 3D simulation graphics data, and developed scene editing tools based on graphic rendering engine——OGRE. The results show that this method will help improve the speed and accuracy of modeling, and that the established interface with engineering data can help design results to be directly used in road traffic simulation.
