【摘要】 提出了一种基于最小二乘的曲面拟合算法,详细介绍了最小二乘法的原理和方法及其应用。采用该算法进行曲面拟合,使拟合的曲面具有精度高,光滑性好的优点。通过弗格森双三次曲面为研究模型来建立最佳的拟合参数。实验结果表明此算法具有良好的拟合效果,模拟曲面真实。目前利用最小二乘来处理拟合问题已经得到了广泛的应用。更多还原

【Abstract】 This paper introduces an algorithm research on the least-squares method(LSM) based surface fitting,and elaborates on basic principle and approach of LSM.By using this algorithm for surface fitting,the fitting of the surface has the advantages of high degree of accuracy and smoothness.At last,through establishing optimal fitting parameters,it is shaped the model of Ferguson bicubic curved surface to surface fitting.The results show that using this method to fit surface is superior and effective.Nowadays,dealing with fitting problem based on LSM has been used widely.更多还原
