Physiological parameter detection method and related apparatus

An electronic device, comprising a photoplethysmography (PPG) assembly, a memory, one or more processors, and one or more programs, wherein the PPG assembly comprises m groups of detection modules, n is an integer that is greater or equal to 2, each group of detection modules comprises one or more detection modules, each detection module comprises one light source and one photoelectric detector, and when the one or more processors execute the one or more programs, the electronic device is caused to perform operations comprising:

• collecting m groups of PPG signals via the m groups of detection modules, wherein each group of PPG signals comprises one PPG signal collected by each detection module in a respective group of detection modules, one PPG signal is obtained in a manner in which a light source in one detection module emits a light ray toward skin and a photoelectric detector in the one detection module detects a light ray reflected from the skin, the m groups of PPG signals comprise a first group of PPG signals, the first group of PPG signals comprises at least signals respectively collected by two detection modules with different spacings, and a spacing of a detection module is a distance between a light source and a photoelectric detector in the detection module;
• determining m physiological parameter values based on the m groups of PPG signals, wherein each physiological parameter value is determined based on one group of PPG signals;
• and
• determining a physiological parameter value of a user based on the m physiological parameter values, wherein the physiological parameter value is related to an arterial activity of the user.
