Title:
METHOD AND DEVICE FOR DETERMINING EVENT PERIOD VALUE
Document Type and Number:
WIPO Patent Application WO/2019/028931
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and a device for determining an event period value, said method comprising: acquiring a time sequence of a target event, the time sequence comprising a pre-set number of sequence values; calculating an autocorrelation sequence of the time sequence, and determining, according to a wave peak value and a wave trough value in the autocorrelation sequence, a first candidate period set corresponding to the autocorrelation sequence; calculating a Fourier transform result of the time sequence, and determining, according to a magnitude value of a frequency point in the Fourier transform result, a second candidate period set corresponding to the Fourier transform result; taking the union set of the first candidate period set and the second candidate period set, determining a total confidence value corresponding to the candidate period values in the union set, and determining a period value of the target event according to the total confidence value. The technical solution provided by the present application can improve the determination accuracy of the event period value in cases where the event period value is automatically determined.
