| 摘 要： | 通过对NURBS曲面重构技术的理论分析和实验研究,得知自由曲面的控制点数量对曲面重构精度有很大影响。在一定曲率半径时,适当增加控制点数量能减少曲面拟合误差,并使所重构的自由曲面更加光顺;而在相同控制点的情况下,曲率半径越小则精度越高,并用具体实例进行了验证。

| Abstract: | By the theoretical and experimental research of NURBS surface reconstruction technology, it is pointed out that the quantity of control points on a free surface has direct effect on the precision of the surface reconstruction. When the radius of curvature is constant, a proper increment of control points improves the precision and smoothness of the reconstructed surface. Similarly, given a set quantity of control points, better precision may be obtained over a surface with a small radius of curvature. Finally, an experiment using NURBS free surface reconstruction method verified the above conclusion. |
