摘要
二维码印刷质量直接影响条码信息传递的准确性。为了分析影响二维码印刷质量的主要因素,基于二维码检验国家标准,研制了二维码图像采集平台。通过制作二维码测试样本,分析了灰度变化和几何变化对符号反差、调制比、轴向不一致、网格不一致等二维码印刷质量参数的影响。实验结果得出不同二维码质量参数分级的图像质量要求,为二维码的印刷质量检测和控制提供参考依据。
The printing quality of QR code directly affects the accuracy of barcode information transmission.In order to analyze the main factors affecting the printing quality of QR code, a QR code image acquisition platform was developed based on the national standards for QR code inspection. Through making QR code test samples,the influences of grayscale changes and geometric changes on the printing quality parameters of the QR code were analyzed, such as symbol contrast, modulation ratio, axial inconsistency, grid inconsistency, etc. The experimental results obtained the image quality requirements of different QR code quality parameters grading, and provided a reference for the printing quality inspection and control of the QR code.
