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。
Due to the complexity and variety of construction drawings, there are many forms of data such as graphics, texts, symbols, tables and so on, which bring great difficulties to the reconstruction of 3D building models based on construction drawings. This paper analyzes the problems of construction drawings Data content and its relevance, this paper proposes a data organization method for 3D reconstruction of buildings, constructs a building object model for data extraction, and designs corresponding data structures and human-computer interaction extraction methods. Based on the construction drawings Information extraction provides a complete set of methods to learn from. The method of parametric decomposition of building construction data composed of frame parameters, basic parameters, extended parameters and semantic parameters is proposed, which can support the relatively independent step-by-step parameter extraction method and design a comprehensive interactive interface to simplify the data extraction The operation process and experiment show that the efficiency and accuracy of data extraction are effectively improved.
