一种有效的从CAD工程图样自动提取零部件信息的方法及其实现

分析了工程图样中标题栏、明细表及产品／部件汇总表的形式和内容，归纳了工程图中表格数据的特点，提出了用自由表格的矩阵表示法有效地解决工程图中自由表格的结构提取问题。同时介绍了从表格获取零部件信息的方法，最后简介了从用ＡｕｔｏＣＡＤ生成的工程图样中自动提取零部件信息，存入企业数据库的实用软件工具。

An Effective Method and Its Implementation for Automatic Extraction of Part Information from Engineering Drawings

In order to reuse the CAD data efficiently, the paper presents an effective method for extracting mechanical part information from existing mechanical engineering drawings produced by CAD software. Characteristics of the forms in the engineering drawings are analyzed. A new method to represent arbitrary forms with matrix is proposed, which makes it easy to extract form frames. Based on the form frames, the part information is obtained. In addition, a practical software tool is briefly introduced, which can be used to extract part information from AutoCAD produced engineering drawings automatically.
