目的 为保证商品条码在物流系统中的快速识别和信息传递,研究条码的质量检测方法。方法 首先分出条码区域,考虑到条码的特殊属性,需要满足其可识读功能,设计针对EAN-13商品条码的印制质量检测方法,包括可识读检测和印刷缺陷检测。根据条码检测的国家标准,条码可识读检测部分,采用扫描反射率曲线分析法和条码质量分级法对条码的可识读性进行判定。条码缺陷检测部分经过条码校正、条码与字符的分割和条码大小的归一化等处理后,选定基于垂直投影的缺陷检测算法对条码的脱墨和污点缺陷进行检测。结果 条码识读程序对合格品和缺陷品的识读准确率都为100%,条码缺陷检测算法程序的平均检测耗时为93.35 ms,检测准确率为94%。结论 条码质量检测系统具有较高的检测准确率,并且能够很好地满足机器视觉缺陷检测速度的要求。 |

The work aims to study the quality detection method of barcode, in order to ensure the rapid identification and information transmission of the commodity barcode in the logistics system. Barcode area was separated firstly. Considering the special properties of barcode and meeting its readable function, the printing quality detection method of EAN-13 commodity barcode was designed, including the readable detection and printing defect detection. On the basis of national standard for the barcode detection, the barcode could read the detected part, and the scan reflectance profile analysis and barcode quality grading method were used to determine whether the barcode could be read. After the part to be detected for barcode defect was treated by barcode correction, segmentation of barcode and character and barcode size normalization, the barcode defect detection algorithm based on vertical projection was chosen to detect such barcode defects as void and spot. The reading accuracy of the barcode reading program for the qualified and defective products was 100%. The average detection time of the barcode defect detection algorithm program was 93.35 ms, and the detection accuracy was 94%. In conclusion, the quality detection system of barcode has higher detection accuracy and can well meet the requirements of machine vision defect detection speed. |
