缺陷检测系统的图像预处理分析与探讨

在晶振外壳缺陷检测系统中,正确识别缺陷的前提条件是得到高质量的预处理图像。图像预处理的目的为了提高系统所采集图像的质量,通过比较分析并采用平滑处理、二值化、形态学处理等一系列图像处理方法对原始图像进行处理,从而得到纹理清晰、缺陷突出的理想图像,为后期的缺陷检测与识别作好铺垫。

Analysis and Exploration on Preprocessing Images of Defects Detection System

Of the defects detection system of the shell of crystal oscillator, obtaining high quality preprocessed image is prerequisite to correctly verify the defects. Digital image processing methods are introduced . The purpose of preprocessing image is to improve the quality of image, and apply the methods such as smooth processing, binary processing, morphology operation to the original images. Finally, the clear veins of the preprocessed images are obtained, which is the basic need of defects detecting
