RESEARCH ON DESIGN METHOD OF HULL SURFACE BASED ON REVERSE ENGINEERING

To shorten the development cycle of new ship form and improve the efficiency of ship design, this paper proposes a digital design method of hull surface based on reverse engineering. The point cloud information of the hull surface is obtained by a 3D laser scanner. The point cloud is aligned, denoised, and simplified by the improved ICP algorithm and chord height difference method. The hull surface is reconstructed in CATIA and the error analysis is performed. The smooth surface with considerable accuracy is obtained. The offsets of the reconstructed hull surface are obtained by the secondary development of CATIA. The lines plan is generated, which can be used in the subsequent redesign. This method provides a novel idea for the design of the new ship form.
