AI Technical Summary
During user exercise, existing technologies struggle to accurately determine heart rate data, especially since ambient light enters the sensor due to the gap between the smart wearable device and the skin, affecting the accuracy of the photoplethysmography (PPG) signal. Data collected by multiple light receivers is inconsistent and cannot be effectively fused.
Vibration acceleration signals and multiple photoplethysmography (PPG) signals are acquired through the user's wearable device. A notch filter is selected to process the target PPG signal to determine the target frequency domain signal. Heart rate data is identified based on each PPG signal. The weight values of candidate heart rate data are determined through the signal spectrum, and finally, the target heart rate data is determined.
It improves the accuracy and consistency of heart rate data during exercise, and achieves more accurate heart rate monitoring through signal processing and data fusion.
