Abstract

Information and communication technology (ICT) can enhance the performance of conventional fibers and the textile manufacturing process. In this work, an image-processing technique was adapted for the automatic inspection of the winding form of yarn packages, which is a critical factor for effective and seamless fiber/textile manufacturing. Raw images were dissected to quadrantal formats and then transformed to rectangular shapes for the ease of processing. Two parameters, fiber orientation angle and shape factor of the fiber orienting bounding box were proposed to filter out badly aligned fibers on the package surface. Various sizes and shapes of packages were used for verification of the proposed method.
