Automated Optical Inspection System for Leather

This technical report presents an automated optical inspection (AOI) system specifically designed for the detection of natural marks on genuine leather. Developed by Dr Schenk, the system integrates proprietary high-speed smart line scan cameras and dedicated illumination units to facilitate the identification of quality zones in leather, a task previously hindered by the diverse appearance of natural marks. The report outlines the components of the system, including the use of multiple illumination configurations that enhance the visibility of color, gloss, and surface structure, allowing for precise flaw detection. The system employs advanced artificial intelligence models to analyze images captured during inspection, ensuring reliable results. Furthermore, it addresses the challenges of handling hides for inspection while maintaining throughput. By automating the inspection process, the system improves defect detection accuracy and increases the yield of usable leather while minimizing manual intervention. The findings indicate potential benefits for various industries that utilize leather, including automotive and fashion sectors.
