摘　　要：工程概预算中,关于闭合钢筋线形式的钢筋量计算要以其形状识别为基础。利用标准DXF文件格式的数据,基于闭合钢筋线几何信息,对钢筋线属性做了形式化表示,并以建筑图中最常见的四边形为例,建立一模糊识别模型。该模型以闭合钢筋线全体为论城,包含一组隶属函数和一系列判别规则。In engineering estimation,the calculation of bars shown with closed polyline is built on the bases of shape recognition.In this paper,by using data of DXF and based on geometry information about those polyline elements,attributes of the bars lines are formalized,and then through an example of quadrilateral which is very common in engineering drawings,a fuzzy recognition model is build up,in which the realm is all closed polyline bars in drawings and there is a set of membership functions and a series of discriminate rules.
