工程图纸图像净化处理

Clean Processing of Engineering Drawing Image

针对灰度工程蓝图的特点提出了图像锐化、二值化、线条保护滤波的净化处理的处理方案，在净化处理中采用了多结构元素形态滤波的新的形态学滤波方法。将一种能够滤除附在图像边缘上的多结构元素形态滤波器和基剪裁多结构元素形态滤波器应用于净化处理。

For any engineering drawing recognition and electronic file system,it is necessary tocarry out preprocessing of the images on the drawings after the engineering drawings arescanned into the computer. Based on the specific features of the density engineeringblueprint,a clean processing scheme with image sharpening, binary system and line preser-vation filtering is proposed.A new morphological filtering method with multiple structuralelements is applied to clean processing, A morphological fiIter with multiple structural ele-ments for removing the noise-corrupted image edges and for preserving the image detail is al-so used.
