建筑平面图理解中对墙体符号的识别方法

An Approach for Wall Symbol Recognition in Understanding Architectural Plans

一些由图纸矢量化或者CAD软件绘制的建筑平面图只包含基本的几何图形元素如线段、弧线等,需要通过符号识别得到关于建筑结构的信息,例如墙体拓扑结构、门窗的位置、型号等。该文提出了一种对建筑平面图的墙体符号识别算法,结合建筑平面图的领域知识,首先利用几何运算从平面图中提取出构成墙体候选符号的子图,再使用逻辑方法推理确定墙体元素符号并得到完整的墙体拓扑结构信息。

In this paper,we propose a method for recognizing architectural symbols and analysing the wall topological structure by domain knowledge.This method exacts the wall candidate subgraph from the architectural plans through ge-ometric operation at first.Then we obtain elements which consist of wall by logical approach,recognize the wall symbol and deduce the wall topological structure.
