摘要

本文提出了一种基于特征值分析的带宽选择方法，用于噪声点云的拟合曲线。首先利用归一化最大特征值选择合适的局部区域半径(带宽);然后利用局部区域的回归线对数据进行排序。最后，利用最小二乘法对局部数据拟合出一个3阶多项式。

An eigenvalue analysis based bandwidth selection method for curve reconstruction from noisy point clouds

In this paper, we propose an eigenvalue analysis based bandwidth selection method for fitting curves to noisy point clouds. Firstly the selection of a suitable local region radius (bandwidth) is carried out by using the normalized maximum eigenvalue. Then the regression line of the local region is used for ordering the data. Finally, a 3th order polynomial is fitted to the local data by using least squares method.
