| 摘 要： | 回顾了密集散乱数量数据点面拟合研究发展情况，针对异形边界自由曲面密集散乱测量数据点，提出一种B样条曲面多步拟合算法，其中涉及边界插值B样条曲面生成、Hardy′s双二次局部插值、规则网格数据点B样条曲面最小二乘拟合等关键技术，通过一个工程实例，对文中提出的B样条曲面多步拟合算法进行了实验验证。

| Abstract: | Many researches about surface approximation for cloudy measured points are reviewed. Focusing on the scattered cloudy points of free form surface with irregular boundaries, a multi-step B-spline surface approximation algorithm is presented, in which some key techniques, such as creation of boundary interpolation B-spline surface, Hardy's multiquadric local region interpolation, least square approximation of B-spline surface for regularized points, are involved. Presented algorithm is tested by an engineering experiment. |
