| 摘 要： | 实现计算机图纸理解的关键在于对图纸中符号的识别,该文提出了一种建筑平面CAD图纸中符号识别的新方法,该方法首先由建筑符号中的几何图元构造出一种矩形网格结构,并用图元与网格之间的约束替换几何图元之间的约束来建立符号的几何特征描述。基于这种描述提出了一个统一的识别方法,最后给出了应用实例,取得了满意的识别效果。

| Abstract: | The key to computerize drawing understanding is the symbol recog ni tion in engineering drawings.This paper presents a new approach for symbol reco gnition in architectural plans.Through constructing one kind of special grid,t his approach can convert the constraint relationships between geometrical eleme nts of a symbol to the constraints relationships between geometrical elements an d these grids.Moreover,based on this special grid,a method for recognizing th e architectural symbol is presented.A prototype application using this recognit ion method shows that it is effective. |
