| description | The invention discloses a frequency determination method and device, a nonvolatile storage medium and computer equipment. The method comprises the steps that a first time domain signal is acquired, and the first time domain signal comprises a vital sign time domain signal; continuous wavelet transform is carried out on the first time domain signal to obtain corresponding first multi-dimensional information, and the first multi-dimensional information comprises time, frequency and amplitude; identifying an interference fragment from the first multi-dimensional information, and setting the amplitude corresponding to the interference fragment to zero to generate second multi-dimensional information; and determining a vital sign frequency corresponding to the vital sign time domain signal according to the second multi-dimensional information. The technical problem that the precision is not high when the frequency of the vital sign signal is determined based on the body surface vibration signal is solved.
