摘要
在三维城市模型中,建筑物三维模型的表达是最为关键的主体部分,然而,由于建筑物空间形态的多样性与复杂性,目前对其模型建立方法仍缺乏基本的共识.基于部件的识别(Recognition by Components,RBC)是有关复杂物体如何分解为可识别的基本几何单元(体元)的理论.文中基于这一理论,讨论了该理论在建筑物模型的可识别性、标准性以及快速建模中的意义,并在此基础上重点研究了构成建筑物三维模型的基本几何单元的构成与分类,以及复杂建筑物在不同细节层次下的模型构建.
The expression of 3D model of buildings is the key when constructing a 3D city model. However, the modeling methods are still being studied due to the variety and complexity of building spatial modality. The theory of Recognition by Components studies how intricate object can be broken down into recognizable basic geometric units ( i. e. , Geon). Based on this theory, this paper discusses its importance on the recognizability, standardization and fast modeling of building model, and emphases are loaded on the structure and classification of basic geometric units that constitute the 3D model of buildings and on how the model of intricate building is established in different levels of details.
