Abstract
There is provided a data similarity calculation method. The method includes: (a) acquiring a first waveform; (b) storing time series data; (c) converting the stored time series data into a waveform on two-dimensional coordinates, wherein the two-dimensional coordinates consists of a time axis and an a value axis representing values of the time series data, and the time axis is orthogonal to the value axis; (d) shifting the converted waveform in both directions of the time axis and the value axis so as to generate a second waveform; (e) calculating a similarity between the first waveform and the second waveform; and (f) extracting a shift amount in the direction of the time axis and a shift amount in the direction of the value axis when the similarity is the highest by repeatedly performing steps (d) and (e).
