摘要/Abstract

摘要： 为提升QR(quick response)二维码在高速运动状态下的识别率，系统分析并筛选了可能影响二维码识别率的因素，进行了基于响应面方法的CCI(central composite inscribed)实验设计。将传送带速度、读码距离、读码角度、照度等因素划分为5个水平，并分别进行了静态、动态实验以及参数优化。动、静态实验结果表明，读码距离、读码角度与照度之间的交互作用对静态下二维码识别率有显著影响(p<0.05)，传送带速度、读码距离、读码距离与读码角度之间的交互作用、读码角度与照度之间的交互作用对动态下二维码识别率有显著影响。理论上，当传送带速度为80.6 m/min，读码距离为144.3 mm，读码角度为-25.6°，照度为683.0 lx时，可得识别率的最大优化值为98.4%。通过实验验证可知，影响因素的参数优化能有效提升二维码识别率。

Abstract: To enhance the recognition rate of QR code in high-speed motion, the factors that may affect the recognition rate of QR code are systematically analyzed and screened, and the CCI experimental design based on response surface method is carried out. The numerical value of belt moving speed, reading distance, reading angle and illuminance are divided into 5 levels, and the static and dynamic experiments and parameter optimization are respectively carried out. Static and dynamic experimental results show that reading distance and the interaction between reading angle and illuminance have a significant impact on the recognition rate of QR code in static experimental (p < 0.05) and belt moving speed, reading distance, and the interaction between reading distance and reading angle and the interaction between reading angle and illuminance have a significant impact on the recognition rate of QR code in dynamic experiments. Theoretically, when belt moving speed is 80.6 m/min, reading distance is 144.3 mm, reading angle is –25.6° and the illuminance is 683.0 lx, the maximum optimization value of recognition rate is 98.4%. Through experimental verification, it can be seen that the parameter optimization of influencing factors can effectively improve the QR code recognition rate.
