PROBLEM TO BE SOLVED: To acquire similar sections among a plurality of time-series data without using a histogram.SOLUTION: Calculation means includes: generating circle-shaped circular series data f(t) by connecting a plurality of series data; setting a range [t,t-T] of t to a section length T as reference data Z(τ) and a section [t,t+L-T-1] of the circular series data f(t) as input data g(x); acquiring a spotting point (x,τ) of the reference data Z(τ) and the input data g(x) using consecutive DP processing; detecting a similar section of the input data g(x) similar to a range [1,τ] of the reference data Z(τ); detecting similar sections of all sections of the circular series data by detecting the similar sections by changing the t from 1 to L; and determining to which section of the plurality of series data the detected similar sections correspond. |
