摘要

为解决纸尿裤生产线上人工检测效率低下的问题

利用Visual C++6.0开发了尿裤标识视觉检测系统。采用彩色工业相机

实时抓取产品图像

对纸尿裤弹性腰围位置和左右腰帖的角度做出分析和判断。弹性腰围检测通过对图像进行亮度、对比度调整

HSI空间颜色提取

动态二值化等方法将弹性腰围从背景中分离出来

通过统计目标区域中有效点的个数判定腰围的位置。腰帖检测采用动态二值化和边缘检测相结合的方法

提取腰帖和背景的边界线

通过扫描法获得腰帖角度。实验证明:该系统可以有效解决光照不足、低对比度、褶皱干扰等问题

稳定地实现纸尿裤标识的在线检测。

Abstract

To solve the problem of low efficiency of manual inspection in the diaper production line

a visual inspection system for diaper label was developed using Visual C++6.0.Production images was grabed with color industrial camera.The diaper elastic waist’s location and waist label’s angle was analyzed and judged.The elastic waist detection separated the elastic waist from the background through adjusting brightness and contrast

extracted pixels with specified color in HIS space

color extracting

and dynamic binarization.The waist’s location was determined by counting the valid pixels in the target area.As to waist label detection

dynamic binarization and edge detection are used to obtain the border of the waist label from background.The label’s angle was obtained by scanning the image.Experimental results show that this system can effectively resolve the problem of weak light and low contrast

fold interference

and realize a stable online inspection for diaper label.
