摘要
目的针对烟用材料纸质样品的颜色测量需求,研发一种基于图谱技术的烟用材料纸质颜色自动测量系统。方法通过相机获取烟用材料纸质样品图像,在图像中选取1个或多个区域作为测量区域,将测量区域位置坐标反馈给电机,电机驱动光谱仪滑动至测量区域,光谱仪获得测量区域的光谱信息,算法模块利用光谱信息进行颜色计算,输出烟用材料纸质样品颜色值。结果此系统大大减少了烟用材料纸质样品颜色检测过程中的人工作业量,实现了自动连续颜色测量。此系统的重复性测试精度都可保持在0.25△E^(*)_(ab)内,达到手持式测色设备测量精度。结论实验结果表明,该系统可以实现烟用材料纸质样品颜色精确和稳定的测量,成本低,有广泛的应用前景。
In this study,we propose a color measurement system based on the image and spectral technology,which can be used to measure the color data of cigarette package printing samples.Further,the images of cigarette package printing samples can be obtained through camera,and some regions are selected as the measurement regions.The spectrometer is moved by the motor to the measurement regions and the spectral reflectance data is so obtained.The color data is calculated by the algorithm module.This system greatly reduces the amount of manual work in the color detection process of cigarette package printing samples,and realizes automatic continuous color measurement.The repeatability test accuracy of this system can be maintained within 0.25△E^(*)_(ab),reaching the measurement accuracy of handheld color measurement equipment.Subsequently,the experimental results indicate that the proposed system can be employed to measure the color data of cigarette package printing samples with a low cost and possesses a wide application prospect.
