摘　　要：通过对形状区域和线性区域的构造，使得工程图形的点阵图像在区域上可由两类具有不同特征的基元组成，即形状基元和矢量基无，并构成标号为Ｄ和Ｌ的区域相邻图。在此基础上，工程图识别的基本步骤是分解、构图和推理。还给出了两个基本的图节点的区域包容算法，它们是推理工作的基础。In geometrical description,thescanning image of an engineering drawing can be takenas a set of complex regions of all sorts of shapes,Two region elements , the shape element,labeled D,and the line vector element , labeled L , are developed for the composition of theimage, Three steps for engineering drawing recognition,i.e. , region decomposition , graphconstruction and graph reasoning, are proposed. Two region containing algorithms for thegraph node are also presented. An example of a graph with line intersection is given.
