基于矢量化的二值工程图符号提取算法

Symbol Extraction Algorithm of Binary Engineering Drawings Based on Vectorization

工程图符号提取是工程图识别的重要步骤 .文中提出一种矢量化算法 ,该算法可以将工程图转换成图的表示法 .在该矢量化算法的基础上 ,又提出一种符号提取算法 。

Extracting symbols is an important step in the engineering drawing recognition. This paper presents a vectorization algorithm, which can transfer engineering drawing to a graph. Based on this vectorization algorithm this paper presents a symbol extraction approach which can extract all kinds of isolated and adhered together symbols effectively.
