[0002] As consumers' demands for personalization and customization increase, the quality requirements for fabrics are also getting higher and higher. Appearance inspection is the first step in fabric inspection, which mainly includes checking the surface quality, color, texture, defects, etc. of the fabric; through appearance inspection, it can be preliminarily judged whether the quality of the fabric meets the requirements. At present, the appearance inspection of fabrics mainly cuts out the corners of a piece of fabric for sampling, and puts the sample into the equipment to detect and evaluate the quality of the fabric; however, this method causes fabric loss, and only checks the sample, which will miss some problems, and the evaluation is not comprehensive and accurate.
