Abstract
This application discloses a vital sign detection method and an electronic device. The method includes: obtaining an acceleration signal and PPG signals of a plurality of channels within a preset time period; calculating, in a case that there is at least one correlation coefficient in the correlation coefficient matrix less than or equal to a first threshold, a variance of the PPG signals of each channel in the plurality of channels; performing frequency domain fusion after performing a FFT on the PPG signals of the plurality of channels, to obtain a frequency domain signal of the fused PPG signal; performing the FFT on the acceleration signal to obtain a frequency domain signal of the acceleration signal; inputting the frequency domain signal of the fused PPG signal and the frequency domain signal of the acceleration signal into a deep neural network to obtain a value of a vital sign.
