Dead reckoning supports stereo vision in pedestrians tracking

Fourth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PERCOMW'06), 2006
This "work in progress" paper reports on a novel approach to pedestrian tracking in confined areas which is based on a combined use of a stereo vision tracking system and a set of sensors available on a mobile platform. This platform is a hands-free, sensory augmented, wearable computer, designed to support visits to museums and archaeological sites ...

A Double-Step Unscented Kalman Filter and HMM-Based Zero-Velocity Update for Pedestrian Dead Reckoning Using MEMS Sensors

IEEE transactions on industrial electronics (1982. Print), 2020
In this paper, we propose a novel method for pedestrian dead reckoning (PDR) using microelectromechanical system magnetic, angular rate, and gravity sensors, which includes a double-step unscented Kalman filter (DUKF) and hidden Markov model (HMM)-based ...

Robust pedestrian dead reckoning using anchor point recalibration

2017 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2017
All indoor positioning approaches face the challenge to deal with erroneous input data from sensors. Especially independent systems like dead reckoning rely on highly accurate input data from accelerometers and gyroscopes for an accurate prediction of the user's position.

An enhanced pedestrian dead reckoning approach for pedestrian tracking using smartphones

2015 IEEE Tenth International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), 2015
This paper proposes an approach for pedestrian tracking using dead reckoning on a standard smartphone. Previous studies report tracking pedestrians when the mobile device is carried in a defined way within the tracking period. This paper presents a new approach which extends and enhances previous methods by identifying three typical modes of carrying ...

A method for dead reckoning parameter correction in pedestrian navigation system

IMTC 2001. Proceedings of the 18th IEEE Instrumentation and Measurement Technology Conference. Rediscovering Measurement in the Age of Informatics (Cat. No.01CH 37188), 2002
This paper presents a method for correcting dead reckoning parameters, which are heading and step size, for a pedestrian navigation system. In this method, the compass bias error and the step size error can be estimated during the period that the global positioning system (GPS) signal is available. The errors are used for correcting those parameters to

Adaptive pedestrian activity classification for indoor dead reckoning systems

International Conference on Indoor Positioning and Indoor Navigation, 2013
A pedestrian activity classification (PAC) system classifies pedestrian motion data into activities related to the usage of specific building facilities, such as going up on an escalator or descending a staircase. Recent studies confirm that use of PAC significantly reduces indoor localization errors of a pedestrian dead reckoning (PDR) system as exact
