To quickly obtain the digital model of ship surface for detection and redesign, a reconstruction method for propeller and ship surface is proposed. Three-dimensional point cloud data of ship hull was obtained by laser scanning technology and the cloud data was preprocessed by iterative closest point (ICP) algorithm and chord deviation method. Then the surface was reconstructed with traditional surface modeling method and fast surface modeling method. By comparing the reconstructed surface with the initial point cloud data, the error of the reconstructed model was obtained. The result shows that the reconstructed surface gains good smoothness and small error. With this method, ship surface can be reconstructed quickly and the reconstructed digital model is of good quality which can be used in detection and redesign.
