The paper adopts the RBF neural network to fit ship lines at the first time and puts forward the method determining the RBF center point sets suitable for fitting ship lines. It shows that the method is of much higher learning speed compared with BP neural network, and is both practical and feasible based on the examination of the fitting precision by using the power function and circular function.

采用RBF神经网络拟合船舶型线，提出了适合船舶型线拟合的RBF中心点集的选取方式，与BP网络相比大大提高了学习速度和精度，用幂函数和圆函数检验本方法拟合曲线的精度，充分证明本方法拟合船舶型线是实用可行的。
