摘要
针对道路网三维建模中成本高、周期长等问题,该文介绍了一种基于规则的道路网三维建模方法。在规则文件驱动下,该方法充分考虑道路网的结构化特征和地理环境,利用抽象化的道路网实体数据和属性信息,实现批量化道路网建模,并在云平台上发布,进而实现道路网三维景观的浏览、查询和分析。采用上述方法实现了一段包含立体交叉在内的道路网的三维模型的快速搭建。结果表明,该方法的规则复用性强、建模效率高、模型调整速度快,为在三维GIS环境下构建道路网模型提供了高效的技术手段。
Aiming at the problems of high cost and long period in 3d modeling of road network,this paper introduces a 3D modeling method of road network based on rules.Under the rule file driven,the method takes full account of the structural characteristics and geographical environment of the road network,and uses abstracted road network entity data and attribute information to realize the modeling of mass road network,and publish on the cloud platform,and then realize the browsing,query and analysis of road network 3D landscape.Using the above method,a 3D model of the road network including threedimensional intersection is constructed quickly.The results show that the method has strong rules reusability,high modeling efficiency,fast model adjustment speed,and provides an efficient technical means for constructing road network model in 3d GIS environment.
