基于NURBS曲面数据的船体体积计算方法的研究

Research on Calculation Method of Hull Volume Based on NURBS Surface Data

应用ObjectARX在AutoCAD上进行二次开发,设计并实现了基于NURBS曲面数据的船体体积的计算程序。与传统的先建立数学模型,再测出特征点、关键点后进行拟合计算的单点测量方法相比,在效率和技术上得到了更好的改进,提高了计量的准确性和可靠性。

Using AutoCAD secondary development with ObjectARX,this paper designs and programs the volume of ship based on NURBS surfaces data. Traditionally, it should establish mathematical model, and then survey feature points and key points to fit the surface. Comparing with the traditional single-point measurement method, the program improves the accuracy and reliability of measurement, having better improvement of efficiency and technology.
