摘要
应用等距结点Ｂ样条的理论，根据船舶型线的形式．建立了三次Ｂ样条的插值 算法。计算结果表明，算法具有较高的精确度，计算灵活．正反插值均可进行．文 中还给出了曲线几何特性的算法及船舶型线边界条件的算法．
The cubic B-spline approximation of equidistant nodes is applied. Three kinds of interpolating methods bascd. on B-spline theory are proposed according to the local characteristics of ship-shape lines. It has been shown that these methods can achieve higher precision in computation and can be used easily in direct or inverse operations.
