色差分布测试仪技术研究
首发时间:2019-05-13
摘要:针对纺织业、制造业等行业对产品色彩一致性的技术需求,论文基于标准色度学原理,以彩色工业相机为传感元件,以白光LED为照明光源,以Python设计了系统软件,完成了成像式色差分布测试仪,实现了传统的基于颜色传感器的色差仪无法实现的色差分布测试。实验结果表明,样品RGB标准值与还原的RGB的相关性均在93%以上,色差的平均误差值优于2.89,满足国家机械行业标准色差误差范围(不大于3)。

Color Study on Technology of Color Difference Distribution Tester
Abstract:For industries such as textiles, manufacturing technical requirements for product color consistency, the paper based on the standard colorimetric principle, industrial camera for sensing element in color, with white LED as lighting source, with Python has designed the system software, completed the imaging type tester, color difference distribution based on color sensor is the traditional color difference meter cannot achieve the color distribution of test. The experimental results show that the correlation between the RGB standard value of the sample and the reduced RGB is more than 93%, the average error value of color difference is better than 2.89, which meets the standard range of color difference error of national machinery industry (no more than 3).
