摘要
手工绘制的工程图的保存和识别是当前CAD/CAM研究中的重要问题。工程图纸一般被扫描为图形文件加以保存 ,这种方法很难满足利用已有的图纸和CAD系统对产品进行改进的要求。为此提出了一种基于对图形分段处理的工程图矢量化方法 ,采用这种方法 ,可自动将影像图形自动转化为几何图形。
It is difficult for computer to recognize the manual engineering drawing. The image file from scanned drawing can not be redesigned by CAD/CAM system. The paper puts forward an algorithm to vectorize the engineering drawing by dividing picture into several parts. With this method the image data can be automatically converted into graphics.
