工程图自动输入中的若干技术问题

The Techniques Used in the Automatic Input Systems for Engineering Drawings

叙述了一个工程图自动输入系统的系统构成，在该系统中，用“拉直”技术对一般的细化方法进行了改进并取得了较好的细化结果，同时也介绍了基于矢量化处理的对直线、粗细线和箭头的识别技术。试验表明，该系统有较高的图形输出质量并达到较高的识别率。

An automatic input system for engineering drawings is presented in this paper. In this system,the general thinning method is improved using straightening techniques.In addition,techniques for recognizing thick lines,thin lines and arrows,based on the vectorization process,are introduced.The experimental results show that good quality graphic output is obtained,and an effective rate of recognition is achieved through the system.
