摘　　要：基于生产日期喷码人工检测缺陷劳动强度大、智能化水平低、效率低等问题,开发基于机器视觉的乳品生产日期喷码缺陷检测系统。该系统采用CCD相机、计算机、光源等搭建硬件平台,利用中值滤波、二值化、图像分割、模板匹配等图像处理技术,实现了对生产日期缺码、模糊码等缺陷检测。试验结果表明,该系统能够准确识别出生产日期有缺陷的产品,达到预期的检测效果。Aiming at the problems of labor intensity,low automation level,and low efficiency in manual inspection of production date defects,the machine vision-based dairy production date coding defect detection system was developed.The system uses a CCD camera,computer,light source,etc.to build a hardware platform,and image processing techniques,such as median filtering,binarization,image segmentation,and template matching were used to achieve the goal of defective detection,including production date missing and fuzzy codes.The experimental results showed that the system could accurately identify products with defective production date,and achieve the expected results,showing practical significance.
