基于图形理解的室内建筑三维重建算法

Arithmetic of 3-D house reconstruction based on graphics understanding

摘要:

根据室内建筑行业特有的视图表示规则，提出了一种基于理解的室内建筑物三维重建方法。该方法结合室内建筑制图规则、图形识别理解技术和人工智能知识，通过基于特征抽取的识别算法，完成对室内建筑结构图中墙体中线的提取，进而获得整个建筑物墙体的拓扑结构；然后对室内建筑结构图中２种重要的建筑构件：门和窗户进行辨识；最后实现室内建筑物的三维重建。实验结果表明，在少量人机交互的基础上，该方法对实际的建筑图是十分有效的。

Abstract:

This paper proposes an arithmetic of 3-D house rebuilding based on image understanding according to the standard rules of graphics in the architecture industry. The arithmetic picks up midlines of walls from the architecture drawing in order to obtain the whole topology of the house combining the rules of architecture drawing, image understanding and artificial intelligence; and then distinguishes two important members: door and window from the graphic; at last rebuilds the 3-D house. The result of the experiment indicates that the arithmetic is effective for actual architecture drawings with the help of man-machine conversation.
