摘　　要：针对现行颜色测量系统体积较大、价格昂贵和适用性较差等问题,开发了一款便携式织物图像颜色测量系统。该系统包括可折叠拆卸的封闭式图像采集装置和颜色测量算法。使用能兼容多种拍摄设备的图像采集装置采集标准色卡图像和织物图像,在此基础上,结合多项式回归算法和K-Means聚类算法,设计了一种分类颜色测量方法,用于对织物图像的颜色测量。该方法根据织物不同颜色类别应用不同的多项式回归模型,以提高测量的准确性和可靠性。经过实验验证,该系统在机织物图像及不同品牌智能手机拍摄的纯色和多色织物的颜色测量中均显示出良好的应用效果,测量结果的平均色差与Digieye颜色测量系统保持了较好的一致性,证明了本系统在织物颜色测量方面的有效性。Objective In the textile industry,fabric color is a critical factor affecting the final product′s appearance and quality.With the dynamic shifts in fashion trends and increasing diversity in consumer demands,the production pace in the textile sector has accelerated,necessitating more diverse and rapidly updated color options.Consequently,developing a convenient and efficient textile color measurement system is vital to meet the industry′s evolving demands.This system is designed for scenarios such as offline trading where traditional measurement system may not be feasible,thereby facilitating accurate color assessment and transactional decisions in the textile domain.Method In this research,a portable fabric image color measurement system compatible with multiple devices was developed,which comprises a foldable,enclosed image acquisition device and an algorithm for color measurement.The design of image acquisition device incorporated a detachable and collapsible structure,enhancing the system′s portability.To ensure accurate color measurement,the study integrated polynomial regression and K-Means clustering algorithms to devise a categorical approach to color measurement.This method involved applying different polynomial regression models based on the specific color categories of the fabrics,thereby facilitating precise color measurement.Results The process began with capturing images of Datacolor SpyderCheckr24 color swatches using a smartphone.Subsequently,these images underwent processing through a classification correction algorithm developed in this study.The analysis of color differences after correction indicated that the performance of this system closely matched that of the Digieye color measurement system,suggesting that smartphone-captured images,when processed through this system,can approximate actual colors.Furthermore,the system was applied to a set of 25 solid-color woven fabrics.The color measurements obtained from these samples were then compared with the results from the Digieye system.Th
