一种三维建筑物模型与数据组织方法

针对施工图内容复杂多样,存在图形、文本、符号、表格等多种样式的数据形式,给基于施工图的三维建筑物模型重构带来较大困难的问题,该文分析了建筑施工图的数据内容及其关联性,提出了面向建筑物三维模型重建的数据组织方法,构建了面向数据提取的建筑物对象模型,设计了相应的数据结构和人机交互提取方法,为基于建筑施工图的信息提取提供了一整套可供借鉴的方法。提出了由框架参数、基本参数、扩展参数和语义参数构成的建筑施工图数据参数化分解方法,可以支持内容相对独立的分步参数提取方式,并设计了综合化的交互界面,简化了数据提取操作过程,试验表明有效提高了数据提取的效率和准确率。

A method for 3D building model and data organization

For the complexity and variety of the construction drawings,and there are many forms of data forms,such as graphics,text,symbols,forms,etc.,which bring great difficulties to the reconstruction of 3D building model based on the construction drawings.In this paper,the data content and its relationship of building construction drawings are analyzed,and a data organization method for 3D building model reconstruction is presented.Then,a building object model for data extraction is constructed,and the corresponding data structure and human-computer interaction extraction method are designed.This paper provides a complete set of methods for the information extraction based on building construction drawings.A data decomposition method is proposed,which is composed of frame parameters,basic parameters,extended parameters and semantic parameters,which can support the extraction of the relative parameters of the content.The integrated interactive interface is designed to simplify the process of data extraction,and the experiment shows that the efficiency and accuracy of the data extraction are improved.
