Pedometer Algorithm Research Based-Matlab

摘要

Pedometer can help people grasp the exercise in real time, through the detection of human walking and running to calculate the distance. In order to improve the accuracy of pedometer, the paper,with the help of Matlab simulation tools, take advantage of the acceleration sensor (ADXL330) axis output signals and the signal energy-based adaptive threshold to detect the number of peak for acceleration signal, in order to accurately calculate the number of steps of human walking.The experimental results show that compared with traditional method, based on signal energy adaptive threshold detection method has better performance, can effectively improve the accuracy of a pedometer.
