Hyperspectral Imaging for Textile Quality Assessment
topic
Hyperspectral imaging systems collect spatially resolved reflectance spectra at 400 to 2500 nanometre wavelength from fabric surfaces at each image pixel, enabling chemical composition mapping that identifies dye distribution uniformity, finish chemical concentration variation, and fibre blend heterogeneity that cause the colour and property non-uniformities not detectable in conventional RGB camera images used for visual appearance inspection.
Role
Provides chemical information from fabric surfaces that standard colour cameras cannot measure, enabling the detection of chemical non-uniformity including patchy finish application, dye migration patterns, and blend irregularities that cause performance variation in finished fabric, with hyperspectral imaging being particularly valuable for process diagnostic investigation of finishing and dyeing non-uniformity problems where the spatial distribution of chemical composition provides causal insight that appearance images alone cannot reveal.
