| 摘 要： | 提出一种新的高斯滤波器B样条函数实现方法。在B样条函数理论基础上,通过对变分原则引入约束条件的方法,并结合小尺度高斯滤波器级联的特性,得出了高斯滤波器的逼近滤波器。其与高斯滤波器的最大幅度偏差小于1%,并且也具有零相移的特性。在相应的滤波算法中,包括了一级零相移滤波和一级加权滤波,只进行二次循环,算法结构简单,计算效率高。对实际表面测量数据进行应用试验,能够满足高斯滤波器实现方法高精度、高效率的要求。

| Abstract: | A new implementation approach for Gaussian filter is presented .Based on the theory of B-spline function, the variational principle with constraint condition and the cascade characteristic of small-scale Gaussian filter, the approximation filter of Gaussian filter is obtained, and its maximum amplitude deviation from Gaussian filter is less than 1%, and it also has the zero-phase-shift characteristic.The algorithm for the approximation filter consists of the zero-phase-shift filtering and the weighing filte... |
