| 摘 要： | 直线是工程图纸中出现频率最多的图元，许多更高层次的图元都是以直线段为基础而得到的，因此直线段的识别在图纸矢量化研究中占有重要地位。针对细化后的扫描图，该文将Freeman针对直线编码提出的3个约束条件应用到直线的识别之中，取得了较好的效果通过两次直线段的合并操作较好地解决了短线段过多的问题，并且恢复了在图纸中占有重要地位的线宽信息。

| Abstract: | Straight-line segments are the most prominent constituent in most engineering drawings. And many high level constituent parts can be generated through line-segments approximation, so recognition for line-segments is the most important stage in vectorization. Three restrictions about Freeman encoding for line are applied to the recognition for straight-line segments in the thinned scanning-drawings. The overabundance of short-line segments is solved through two line-merging procedures and the line-width is also extracted. |
