工程图识别中实现图素完整拼接的索引表方法

THE INDEX TABLE METHOD TO IMPLEMENT INTEGRAL CONNECTION OF GRAPHIC SEGMENTS IN RECOGNITION OF ENGINEERING DRAWINGS

本文通过建立两个相互依赖的索引表,采用搜索和比较技术构造并实现了具有相同属性的基本图素的拼接算法。该算法大大地减少了矢量跟踪产生的许多短矢量图素,实现了图素描述的完整性,从而提高了图形识别的整体水平。

By building two interrelated index tables and using certain searching and comparison methods, the paper proposes an algorithm to realize the connection of graphic segments possessing identical attributes. The algorithm reduces a large amount of short vector segments resulting from vector tracing and realizes the integral description for whole graphic primitives.
