IMU signal-based heart rate variability parameter acquisition and calculation method

The invention relates to an IMU (Inertial Measurement Unit) signal-based heart rate variability parameter acquisition and calculation method, and has the following beneficial effects that the invention provides a non-wearable non-inductive HRV (Heart Rate Velocity) parameter monitoring device which is simple in structure, and the device is used for analyzing and detecting HRV parameters of a human body, and the accuracy is equivalent to that of a traditional wearable device. The invention further provides a method for correspondingly analyzing the HRV parameter by using the IMU signal, the HRV parameter can be correspondingly calculated by using the IMU acceleration signal or angular velocity signal detected by the non-wearable equipment, and by adopting the method, a detected person does not need to wear the equipment all the time, and only needs to lay related equipment on a bed, so that the HRV parameter can be correspondingly analyzed. Therefore, the HRV parameters of the detected person can be detected i
