局部数据集与噪声数据曲线的平滑过滤

Smoothing Noise Data Curves by Using Local Data Sets

文中提出了“局部数据集”的概念,并根据“局部数据集”中数据内在的相关性,利用最小二乘法等方法,来达到过滤工程测量数据中的噪声,平滑工程曲线的目的。

The paper elaborates on the concept of Local Data Sets. According to theinherent relevancy of data in the Local Data Sets, and by using the least square method,the aims of filtering noise in engineering survey data and smoothing the engineering curves are obtained.
