The colorful nature of ribbons makes automatic optical inspection difficult. Due to the complex fabric patterns, it is difficult to find specific feature points. Automatic optical inspection (AOI) is prone to missed detection or misjudgment of defects due to changes in patterns and colors.Using the Segmentation technology in SolVision to detect ribbons of various colors and patterns can accurately find the location, size and shape of defects such as holes and loose threads. Both the detection speed and accuracy can meet the standards. By recording and analyzing the appearance of defects, it is possible to trace back the problems in the manufacturing process and improve the product process.
