摘要 结合NURBS曲面的构建理论,以工程软件UG为平台,探讨了基于截面特征点云的NURBS自由曲面构建的工程实现方法。实现了由截面特征点云进行NURBS曲线拟合,再由拟合曲线进行自由曲面的构建过程,并从曲面的表面状态与误差两个方面对构建的自由曲面进行评估。实践表明:采用该方法构建的自由曲面能保证NURBS曲面拟合质量,且精度高,能有效地反映实物原型。 By combining the theory of NURBS surface construction,using UG as an engineering software platform,discussed the method of engineering implementation for NURBS freeform construction from points-cloud of sectional feature.With an example,achieved the process by the NURBS curve fitting from points-cloud of sectional feature,and then by the NURBS surface construction from fitted curves,also assessed the constructed freeform surface from both of the surface state and errors.Example showed：by this method,could guarantee the quality of NURBS surface fitting,could construct a high precision surface and could effectively reflect the physical prototype.
