基于图形约束的工程图纸扫描图象表面粗糙度的自动识别

AUTOMATIC RECOGNITION OF SURFACE ROUGHNESS OF SCANNED IMAGE OF ENGINEERING DRAWINGS BASED ON GRAPHICS CONSTRAINT

本文通过分析现有工程图纸扫描图象的识别与理解系统，提出了表面粗造度的自动识别算法，从而弥补了以往系统的不足．基于图形约束的表面粗糙度整体识别算法符合技术人员的读图规律，处理速度快，可靠性高．该算法已在微机上调试成功．

Few papers about surface roughness recognition of scanned images of engineering drawings have been published. This paper proposes a global approach to surface roughness recognition based on graphics constraint. This method is simple and reliable. It can be used for reading engineering drawings.
