In order to accurately present the complex hull structure and curved surface shape and improve the rationality of ship styling design, the styling design method of large ships based on digital technology is studied. Through the non-uniform B-spline method in digital technology, the surface of the large master ship is reconstructed, and a three-dimensional digital model of the large master ship is established to accurately present the complex hull structure and surface shape. In the Visual Basic operation line library of digital technology, the three-dimensional digital model is imported. Through the rhombus coefficient adjustment method and the transfer method, the rhombus coefficient and the longitudinal position of the floating center of the master ship are adjusted to obtain the preliminary design results of the large ship's modeling. By using Gauss's theorem, calculate the hydrostatic parameters of the large ships in the preliminary design, adjust the preliminary design results, ensure that the large ships meet the hydrostatic requirements, and obtain the fine modeling design results of the large ships. Experiments prove that this method can effectively reconstruct the surface of large master ships and establish three-dimensional digital models. This method can effectively complete the styling design of large ships and meet the hydrostatic requirements.
