Method and telemetric device for resampling time series data

Abstract

The present invention relates to a method for resampling time series data and to a telemetric device configured to resample measured time series data. A method for resampling time series data comprises the following steps: determining a first time series 10 comprising a sequence of data points Pi; determining a variation V of the data points Pi within a selected sequence of data points, wherein the variation V is determined by determining linearly interpolated data points Qi for the data points Pi of the selected sequence and by determining a maximum absolute difference V between the data point value Pi and the corresponding interpolated data point value Qi for the data points of the selected sequence. If a determined variation V of the data points within the first time series 10 is greater than a predetermined error value ε, subsequences are selected by repeatedly dividing the first time series 10 into adjacent subsequences until the first time series 10 comprises a set of subsequences, wherein a determined variation V for each of the subsequences is smaller than the predetermined error value ε. A resampled time series 100 is created by adding the data points Pi of the first time series 10 that correspond to a first or last data point of the selected subsequences to the resampled time series 100, wherein every data point Pi is added only once to the resampled time series 100.
