Abstract

In heavy industry, especially in the shipbuilding process, 3D profile measurement of large-scale hull pieces is needed for fabrication and assembly. Currently, using many kinds of templates made of wood or plastic still do an important role as a standard ruler. We suggest an efficient method of 3D profile measurement to obtain the xyz-coordinates of curvature plates. The measurement system comprises multiple line structured laser sources and performs profile measurement by projecting structured light source on the object surface. The measurement results show that measurement accuracy is within the boundary of accuracy required in the shipbuilding process.
