In recent years, studies on various 3D scanner applications, including those on quality control and reverse engineering, have been conducted in the shipbuilding industry. Appropriate scanner selection, scanning environment setting by targets, and data postprocessing are essential for effective 3D scanning projects for small crafts. In this study, a non-contact handheld-type 3D scanner was used for molds and hull products for the 10– 30-ft class of small crafts. Small crafts have fewer geometric features and several glare surfaces; thus, anti-glare and texture feature addition preprocessing is critical. The 3D scanning results are used for geometry quality control of single panels and curved surfaces in craft hulls. Consequently, international rule-based weight estimation calculation sheets have been developed and applied for product weight quality control.
