3D modeling of city building and lifecycle simulation

Abstract : With the construction and development of the smart city, how to construct the realistic 3D model of the large-scale city buildings quickly and efficiently which becomes the research hotspot. In this thesis, a novel 3D modeling approach is proposed to quickly and efficiently build 3D model of large-scale city buildings based on shape grammar and facade rule modeling. Building Information Model (BIM) is an important technical means to enhance the construction industry, for the city building design and construction, how to better research and application of BIM technology which is the key, in this thesis City Building Integrated Information Model (CBIIM) is specified to manage the information of building lifecycle effectively and realize the information sharing and exchanging. This thesis has studied the acquisition and processing of the modeling data. Google Earth and ArcGIS software are mainly used to acquire and process image-maps data and elevation-maps data of the target area, these two kinds of data match and overlay, which can generate 3D city terrain data with geographic location information. Then OpenStreetMap is used to acquire road data of the target area, and it can be optimal processed to the necessary road network by JOSM software. 3D laser scanning technology is used to collect building surface texture images and create the point clouds model of the target architecture modeling so as to get the modeling dimensions by measurement. On this basis, this thesis mainly has studied the principle and the process of CGA rule to create building models, and studied the method that can separate architectural elements using image segmentation to generate CGA rule automatically and to create building model furtherly. Thus 3D building models have been established in the CityEngine software using CGA rules and facade modeling technology. This thesis has specified the City Building Integrated Information Model (CBIIM) based on BIM. The city building information are classified and integrated, and the building and component was described with the IFC standard, in order to manage the informations of building lifecycle effectively. This thesis studies the integrated information association model technology, that it can realize standardized component design with associated features and intelligent building design with associated parameters in knowledge rules combined with IFC. The construction simulation technology is studied. The knowledge rules in the integrated information model provide a reliable reference for the construction simulation, and the simulation scene is created through the invoking the integrated information model, thus the construction simulation process is completed by the program. Taking Baoshan Campus of Shanghai University as an example, the modeling process of the whole scene is illustrated, and the modeling steps of all kinds of 3D objects are described in detail to solve the specific problems in the actual modeling process. Thus the feasibility and validity of the procedural intelligent modeling approach are verified. Taking the dormitory of Shanghai University as an example, a simulation scene and the simulation model were created by the integrated informations, combined with the relevant construction information the construction simulation was completed by the program. Thus the feasibility and validity of the CBIIM are verified.
