A shoe midsole is manufactured by the phylon mold method in which each product is manufactured successively with differing dimensions due to deformation, and it hinders the automation of shoe manufacture with issues such as size inspection or cement spraying. To address this drawback, it is necessary to perform real-time 3D scanning of the inline conveyor. For the footwear industry, a 3D scanner should have the necessary precision, reasonable cost, and processing speed higher than a commercially available 3D scanner. The optical non-contact method with a line laser is adopted for 3D shape measurement. A laser stripe extraction method and a mathematical model for constructing 3D information are proposed. Unique jig shape and a mathematical method for estimating machine parameters are also expressed. The method of extracting meaningful features from the acquired point cloud and treating the abnormal data in toe and heel is discussed.
