Abstract:

In order to address the problem in color difference between spectrophotometry and spectral imaging when measuring the same fabric, Datacolor 600 spectrophotometer, Datacolor Spectravision and hyperspectral imaging system HIS were chosen to measure the same set of monochromatic cotton knitted fabrics. The reasons and mechanisms for the difference in color and in spectral reflectance measured by the three instruments were discussed. The color difference and spectral similarity between different instruments were calculated, and the data were analyzed by Pearson correlation coefficient method. The results show that HIS has good repeatability with the average color difference being 0.154. The spectral reflectance measured by the three instruments have strong similarity. Compared with Spectravision, the chromatic value of HIS is closer to the spectrophotometer. Spatial feature information is the main factor affecting the color and spectral reflectance. The pixel size of Spectravision are smaller, and Spectravision has a lower brightness due to the influence of shadow of yarns and fabric texture. The pixel size of HIS are proportional to the distance between the camera and the specimen, and HIS is applicable to a broader range.

Key words: fabric, color measurement, spectral imaging, spectrophotometry, color difference, spectral reflectance
