Pedestrian dead reckoning for MARG navigation using a smartphone
The demand for navigating pedestrian by using a hand-held mobile device increased remarkably over the past few years, especially in GPS-denied scenario. We propose a new pedestrian dead reckoning (PDR)-based navigation algorithm by using magnetic, angular rate, and gravity (MARG) sensors which are equipped in existing commercial smartphone. Our proposed navigation algorithm consists of step det...
متن کاملVector Graph Assisted Pedestrian Dead Reckoning Using an Unconstrained Smartphone
The paper presents a hybrid indoor positioning solution based on a pedestrian dead reckoning (PDR) approach using built-in sensors on a smartphone. To address the challenges of flexible and complex contexts of carrying a phone while walking, a robust step detection algorithm based on motion-awareness has been proposed. Given the fact that step length is influenced by different motion states, an...
متن کاملDead Reckoning from the Pocket
We present a novel approach to enable dead reckoning in a scenario with unconstrained placement of a device in the user’s trouser pockets. Utilizing the rotation of the device due to body motion, we estimate the user’s walking direction robustly to different placements in the pocket and without additional body-worn sensors.
متن کاملContinuous Motion Recognition for Natural Pedestrian Dead Reckoning Using Smartphone Sensors
Among various indoor navigation technologies, Pedestrian Dead Reckoning (PDR) is an algorithm based on Magnetic Angular Rate and Gravity (MARG) sensor arrays including accelerometers, gyroscopes and magnetometers which are gradually integrated into smartphones along with the continuous miniaturization of micro electromechanical system (MEMS). Usually, PDR is adopted to provide means of reducing...
متن کاملPedestrian Dead Reckoning and its applications
First, we briefly introduce the technologies of PDR (Pedestrian Dead Reckoning) that can be used to track the location and orientation of a pedestrian. Secondly, we show some enhancement of the PDR to improve its performance on accuracy. Finally, we describe the applications of the PDR.
