In heavy industry, 3D surface measurement of large-scale hull pieces is needed for fabrication and assembly. Until now, there is not such an efficient method as a standard ruler on 3D profile measurement of large-scale curvature plates. We suggest an efficient method of 3D profile measurement to obtain the xyz-coordinates of curvature plates. The measurement system comprises a few slit beam lines and performs profile measurement by projecting structured light source on the object surface.
