摘　　要：主要介绍自由识别和指定位置识别2种自动识别船体型线的方法。运用AutoLISP语言直接读取绘制二维型线时所有控制节点的二维坐标,获取二维型线上指定位置插值点的二维坐标,并利用型线与指定位置在船体上的实际位置的关系将这些节点坐标转化为三维型值。通过算例验证采用该方法求取船体型线三维型值的高效性和准确性,以及导入Solidworks软件进行三维建模生成船体曲面的可行性,为船舶设计由二维向三维转化提供参考。This article mainly introduces two methods for automatic recognition of hull lines which are free identification and designated position identification.AutoLISP language is used to directly read the 2D coordinates of all control nodes when drawing a 2D profile,and to obtain the 2D coordinates of interpolation points at specified positions on the 2D profile,then convert these node coordinates into 3D values using the actual position relationship between the profile and the specified position on the ship's hull.The efficiency and accuracy of using this method to obtain the threedimensional values of hull lines with numerical examples,as well as the feasibility of importing Solidworks software for threedimensional modeling to generate ship surface are verified.This study provides a reference for the transformation of ship design from twodimensional to threedimensional.
