摘　　要：城市三维模型已经在城市建设、社会服务等诸多领域得到广泛应用,为快速、精确地构建三维城市模型,满足城市精细规划和管理的需求,本文围绕快速、合理、准确地构建真三维模型这一主线,以城市地形和地物为研究对象,提出了由地形到地物、由概略到精细的城市三维模型快速构建方案,实现了城市基础地形、建筑物和其他三维场景的快速建模,并基于Skyline平台对提出的建模思路进行了具体的实现,形成了完整的操作流程。The 3D models of cities have been widely applied in various fields such as urban construction and social services.In order to rapidly and accurately construct 3D city models to meet the needs of urban detailed planning and management,this article focuses on the main theme of fast,reasonable,and precise construction of true 3D models,with city terrain and urban features as the research objects.It proposes a fast construction solution for city 3D models,starting from terrain to features,and from rough to precise.It realizes the rapid modeling of urban basic terrain,buildings,and other 3D scenes.The proposed modeling approach is specifically implemented using the Skyline platform,forming a complete operating process.
