Comparison of Time Domain Step Counting Method for Pedestrian Dead Reckoning

Abstract

The problem of step counting has been considered for personal navigation while walking and using mobile sensors with low accuracy.Step counting has been realized by three main methods of processing the acceleration vector magnitude in time domain. The comparison of this methods has been done while processing the data from mobile phone sensors for different conditions and types of pedestrian/their motion patterns. In order to have representative statistics the walking trajectories have been selected long enough (at least 100 meters) except the method of normalized auto-correlation based step counting where short distances have been processed. The requirements to definite method of step counting have been formulated.
