摘要
Abstract
Step counting is an important part of inertial navigation.MEMS sensors are widely used in inertial navigation.The traditional algorithm of step counting uses the acceleration data based on the peak detection method based on the accelerometer data.This algorithm combines the peak detection algorithm with the crossing middle threshold algorithm.The MEMS device obtains the accelerometer data and calculate the steps and routes with the algorithm.The algorithm can determine the possible points from the accelerometer data,judge the valid pedometer point,and calculate the walking steps.It can also give the walking routes combining with step length,step numbers and the direction.Experimental results show that the error of the proposed algorithm is about 0.75%,and tracks are close to the actual walking routes.This algorithm has good performance with different people and in different circumstances.关键词
