摘要
提出了一种基于NURBS曲面的散乱点参数曲面拟合方法,可以对散乱点云数据进行插值或基于最小二乘意义下的光顺拟合。完成了软件开发并在汽车车身外形曲面设计中得到了应用。NURBS曲面的优良品质保证了这种方法计算稳定,生成的曲面满足光顺要求。
A parametric surface fitting method based is presented on NURBS, which enables scattered points to be used for interpolation and approximation and then to generate smooth surfaces with the least square method. The algorithms and relevant software derived and developed are successfully applied in automotive body outer surface design. The method ensures the calculation stability and smooth surface quality.
