Due to various factors in the production process of textiles and leather, non-woven fabrics often exhibit defects such as dirt, loose threads, damage, poor dyeing, and localized texture irregularities on their surface, severely impacting product quality and corporate image. The textile and leather surface defect detection system, based on advanced machine vision technology and combined with the sparse and textural characteristics of the product, utilizes a combination of front-side illumination and back-side transmission imaging to perform high-speed and accurate online surface defect detection. This equipment also provides online alarm, quality report statistics, and product quality classification functions. It offers an effective solution for improving enterprise production informatization and enhancing product quality.
