摘要： 为了根本解决手绘工程图纸与CAD/CAM系统的输入接口之间的矛盾,本文在分析工程图处理特点的基础上,提出了工程图纸数据自动转换到 CAD/CAM系统的基本设计方法。讨论了系统一般实施过程及实施过程中的一些技术问题,并提出了一些算法和进一步研究的课题。本系统采用工业摄像机作为输入手段,以微机作为主体,针对一定约束的图纸,实现了整个图纸的转换过程,获得了满意的效果。

Abstract: In order to set up the input interface between highly developed CAD/CAM systems and a lot of freehand drawings, this paper presents some basic methods and a general procedure for transferring engineering drawing data to CAD system, and discusses some key techniques. Based on the normalized engnieering drawing, the system is implemented on IBM PC/AT installed with TV camera.
