摘要
以建筑AutoCAD矢量图形文件为研究载体,以墙体为主要研究对象,设计了墙体数据深度优先探测提取算法。根据提取出的墙体数据集合,设计了基于凹点分割的墙体裁剪算法,该算法已在实践中进行了反复验证,高效可靠。在此基础上提出了以中轴线+属性形式代替墙体的设计思想,构建墙体抽象模型,为建筑工程量自动计算提供数据支持。
In this paper, based on AutoCAD vector graphics, it just makes the wall′s data as the main object, and designs the algorithm to detect wall′s data by depth-first. To depend on the extracted wall′s data, the clipping algorithm is designed through of concave point, which has been verified in practice efficient and reliable. In above all, it creates model by the axis of the wall and attributes from design files in order to support for automatic calculation of architectural design.
