摘要
Abstract
Recently,heart rate monitoring using wrist-type PPG (PhotoPlethysmoGraphy) is the main measurement device for the heart rate detection.But it is a difficult problem,since the signals during subjects' intensive exercise are contaminated by strong motion artifacts caused by subjects' hand movements.The accuracy of the algorithm based on PPG signal to obtain heart rate is greatly reduced,and the existence of motion artifact increases the difficulty of spectrum analysis of PPG signals.In this study,we propose a modified algorithm for heart rate monitoring based on three-axis accelerometric data,it consists of two key parts,and heart rate estimated by exercise intensity and obtained final heart rate by caiman filter.Experimental data recorded the fast running results of ten subjects with 10 ~ 16 km/h,and the test data showed the absolute mean error of the proposed heart rate correction algorithm was 2.05 BPM.关键词
