摘要:乡村住宅通常以村落形式构成集合，且受地理环境影响较大，因此在设计与建造过程中需要同时考虑单体建筑、村落布置与地理环境等因素。为此，本研究提出了一种面向GIS与BIM多源数据的信息集成与模型轻量化方法，包括：一，基于FBX SDK实现了FBX的自动集成; 二，引入顶点重要度与模型特征因子控制模型的简化过程，实现了面向乡村住宅的QEM改进算法。上述方法从扩充平台的使用场景和提高平台的模型处理能力两个方面，完善了一个已有的乡村住宅轻量化集成平台。研究成果在江苏省徐州市某乡村的改造中进行测试，验证了技术的可行性与实用性，有利于促进信息技术在乡村住宅设计与建造中的推广与应用
Abstract: Rural houses usually combine into villages and are greatly affected by the geographical environment. Therefore, in the process of design and construction, factors such as building information, village information and geographical environment need to be considered at the same time. This study proposes an integration method and a lightweight method for GIS and BIM multi-source data, including an automatic integration method of FBX based on FBX SDK and an improved QEM algorithm for rural housing, which uses vertex importance and model characteristic factor to control the simplification process. The above methods improve an existing rural housing lightweight integration platform from two aspects: expanding the applicable scenarios of the platform and improving the model processing ability of the platform. Taking a village in Xuzhou City, Jiangsu Province as an example, the methods are applicable, practical, and usable. This study promotes the research and application of information technology in rural housing design and construction.
