Description

Technical Field

[0001] The present invention relates to the field of optical detection technology, and more particularly to an aurora testing system and method for uniform fabrics. Background Art

[0002] The aurora phenomenon refers to the abnormal increase in surface gloss or the appearance of mottled light spots when a fabric is subjected to frequent friction, pressure, or stretching, seriously affecting the appearance of clothing. This problem is particularly prominent in wool and blended uniform fabrics. In the early days, the industry relied on manual visual judgment of the degree of aurora, but this was highly subjective and lacked quantitative standards, resulting in large fluctuations in the quality of different batches of fabric. Currently, the detection of aurora phenomenon in uniform fabrics mainly relies on traditional gloss metering, which has obvious limitations. Manual visual inspection is highly subjective, greatly affected by ambient light and personnel experience, and cannot provide quantitative data. While ordinary gloss meters can measure surface reflectivity, they have difficulty distinguishing aurora from normal highlight areas, resulting in a high rate of misjudgment.

[0003] In recent years, machine vision and artificial intelligence technologies have been gradually applied in the field of textile inspection, providing new solutions for aurora testing. Through multi-angle light source imaging and image analysis algorithms, the reflective characteristics of the fabric surface can be accurately captured. Combined with AI models, aurora can be distinguished from ordinary gloss, enabling automated inspection. However, existing technologies lack intelligent measurement of fiber orientation, relying solely on surface reflective characteristics for judgment. They lack quantitative measurement of the microscopic arrangement direction of fibers and fail to combine fiber orientation with gloss changes for comprehensive analysis. As a result, the accuracy and reliability of aurora detection still need to be improved. Furthermore, there is a lack of quantitative comparison of aurora test gloss, making it impossible to accurately assess the impact of aurora on the gloss of uniform fabrics. Summary of the Invention
