摘要
将二维Vondrak滤波与多面函数拟合相结合应用到高程异常的拟合中,实例证明此方法在高程异常拟合中的应用是可行的,与单纯的多面函数拟合法相比,最大精度可提高76.4%,中误差降低54.72%。
The 2D Vondrak filter combined with the multisurface function was used in the height anomaly fitting.The experimental result shows that it is a practicable method in the height anomaly fitting.Compared with the multisurface function fitting method,the accuracy have been greatly improved to 76.4% at most.The standard error has decreased up to 54.72%.
