AI Technical Summary
Technical Problem
Existing technologies often suffer from low accuracy or identify non-actually closed regions when identifying closed regions composed of wide lines due to the gaps between the body lines.
Method used
By extracting the set of wide lines from the design drawings, we can find target wide lines whose ends are in contact, extend the body line to the extension point, fill the gaps between the wide lines, and identify closed areas.
Benefits of technology
It improves the recognition accuracy of closed areas, avoids recognition failures caused by gaps in the body lines, and ensures that the recognition results are consistent with the actual business scenarios.

Abstract
本公开涉及计算机辅助设计技术领域，公开了一种基于宽线的封闭区域识别方法、系统、设备和存储介质，宽线包括本体线和宽度属性，且宽线为将本体线按照宽度属性中的宽度扩展后得到的线条；方法包括：提取设计图纸中的宽线，得到宽线集合；针对任一宽线，在宽线集合中查找与该宽线的宽线端头存在接触关系的目标宽线，接触关系为相容、相切、相交中的其中一个；针对任一宽线以及与该宽线的宽线端头存在接触关系的目标宽线，延伸该宽线和目标宽线的本体线，得到该宽线与目标宽线的延伸点；在宽线集合中，基于各个宽线的延伸至延伸点的本体线，识别宽线构成的封闭区域。识别精度较高。
