智能标贴视觉检测系统设计及应用

Design and Application of a Label Vision Testing System

标贴是各种家电产品非常重要的识别标志,数量大且种类繁多,标贴印刷后和使用前都需要人工检查印刷质量,效率很低。本文设计一种暗箱和白色光源系统,并选择高分辨率的工业相机,实现高精度的图形采集,在HALCON视觉软件平台下,开发一种视觉建模和视觉灰度测试软件,实现最大A3幅面标贴的高精度防错印、防划痕和污迹检测,极大地提高了标贴印刷质量检测效率。

Labeling is a very important identification mark for various household appliance products,with large quantities and various kinds.It is inefficient to check the printing quality manually after printing and before using the label.In this paper,a camera obscura and white light source system is designed,and a high resolution industrial camera is selected to achieve high-precision image acquisition.Under the platform of HALCON visual software,a visual modeling and visual gray testing software is developed to realize the highprecision anti-misprint,anti-scratch and anti-stain detection of the A3-FORMAT label,the efficiency of label printing quality detection is greatly improved.
