【摘要】：随着各地数字城市(智慧城市)建设的推进,大尺度三维建模方法的研究日益受到重视。将参数化技术应用于城市三维场景建模,日益受到学界和企业界的重视。本文基于CityEngine的参数化建模技术,对城市两类重要目标道路和建筑的参数化建模进行了研究,通过扩展现有规则,创建了符合国内实际的城市道路与建筑三维建模的规则模板。以杭州市城西某一街区为实验区,以道路中心线和建筑物平面轮廓为初始的建模对象,应用所创建的、面向道路和建筑的建模规则,快速地实现了实验区的三维建模。基于参数化技术的三维建模方法将重复工作整合到规则代码中,避免了大量重复式的手工建模,通过应用规则,能快速生成道路、建筑模型,可调整的模型参数为后期修改提供了极大的便利。通过输出为通用的3d格式,本文所构建的三维模型可应用于城市规划设计、建筑景观设计、城市管理、应急救灾、环境保护、虚拟旅游等诸多领域。
[Abstract]:With the development of digital city (intelligent city), the research of large scale 3D modeling has been paid more and more attention. The application of parameterization technology to urban 3D scene modeling has been paid more and more attention by academia and business circles. Based on the parameterized modeling technology of City engine, this paper studies the parameterized modeling of two kinds of important target roads and buildings in cities. By extending the existing rules, a rule template for 3D modeling of urban roads and buildings is created, which conforms to the actual situation in our country. Taking a block in the west of Hangzhou as the experimental area and taking the central line of the road and the outline of the building plane as the initial modeling object, the 3D modeling of the experimental area is realized quickly by applying the established modeling rules for the road and the building. The 3D modeling method based on parameterization technology integrates the repeated work into the rule code, avoids a lot of repetitive manual modeling, and can quickly generate the road and building model by applying the rules. Adjustable model parameters provide great convenience for later modification. The 3D model can be used in many fields, such as urban planning and design, architectural landscape design, urban management, emergency relief, environmental protection, virtual tourism and so on.
