摘要： 提出了一种基于图线和行程段特征分析，由行程段直接拾取整条图线的工程图识别算法．该算法不经过图段分割．根据整条图线的信息确定交点；通过分析线素、间隔等的规律确定线型．最后，基于工程图知识进行图线校正．该算法已付诸实践并取得良好效果．

Abstract: in this paper, a new approach to extract the global lint from scanned images of engineering drabs, drawings is proposed on the basis of the feature analysis of line and run. According to the information of the global line, the line intersection point is decided, and the line type is got from analyzing the line element and interval. Finally, the topological relation among lines is adjusted according to the general knowledge of engine, ring drawings. The results demonstrate the effective of this method.
