摘要
提出一种改进的散乱数据曲面拟合算法,利用自适应区域分解法和QR分解法,提高了算法的稳定性,采用双三次Bezier曲面插值拟合散乱数据点,解决了拟合曲面的光滑性问题,最后给出了算法实例和结果分析.
An improved algorithm of surface fitting for the scattered data is introduced. The adaptive domain decomposition method and QR decomposition method are used to improve the stability. The bicubic Bezier patches interpolation is used to deal with the smoothness of the surface. In the end, the algorithm implementation and the results analysis are given.
