개인항법시스템을 위한 GPS 기반 실시간 보폭 보정

Abstract

PDR(Personal Dead-Reckoning) is a kind of navigation system that provides pedestrians position using own inertial and magnetic sensors. The main algorithm of PDR is composed of step detection, step length estimation and heading estimation algorithms. In this work, a step length compensation algorithm using GPS is introduced. This algorithm calibrates step length parameters using GPS and provides more convenient process for users.
