[0002] 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. With the increasing demand of consumers for personalization and customization, the market's requirements for color diversity and accuracy are becoming increasingly stringent. However, whether it is caused by the quality of the dye, the absorption and dyeing properties of the textile material, or slight changes in the production process, the color of the final product may not match the original design or customer requirements. Therefore, the final color of the fabric is one of the key indicators of product quality.

[0003] Due to different lighting conditions, the color of fabrics will be visually different. In order to ensure the consistency and accuracy of color evaluation in each link of the entire supply chain from raw material procurement to finished product delivery, the industry widely uses light boxes to test fabrics.
