摘要
在变形监测中,由于监测外界条件的变化,获取的数据中包含有噪声。其中,随机噪声伴随整个观测过程。为了获得较好质量的数据,有必要对数据进行预处理。该文利用线性滑动平滑原理来消除原始观测数据中的随机噪声,这种噪声大部分为高频噪声。
Because of the change of monitoring environment condition, the obtained data includes some noise in deformation monitoring. In which the random noise accompanies along the whole process of observation. In order to get good quality data, we need to have a pretreatment for data. In this article, we use the theory of linear slippage smoothness to eliminate the random noise in data, the noise mostly is high frequency.
