Pedestrian Dead Reckoning with Turn-Based Correction
2018 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2018Pedestrian dead reckoning (PDR) is a popular localization approach. However, PDR is error prone at turning points. During a turn, a small error in heading estimation can cause severe accumulated positioning errors thereafter. In this paper, we propose a turn-based correction approach which aims to reduce the potential accumulated errors caused by ...

Strap-down Pedestrian Dead-Reckoning system
2011 International Conference on Indoor Positioning and Indoor Navigation, 2011This paper presents a waist-worn Pedestrian Dead Reckoning (PDR) System that requires minimal end-user calibration. The PDR system is based on an Inertial Measurement Unit (IMU) comprising of a tri-axial accelerometer, a tri-axial magnetometer and a tri-axial gyroscope.

An Indoor Collaborative Pedestrian Dead Reckoning System
2013 42nd International Conference on Parallel Processing, 2013Indoor localization has become a popular topic in recent years. While self-contained pedestrian dead reckoning (PDR) systems can be conveniently implemented on a smartphone with built-in inertial sensors for indoor localization, the error of the estimated position for a PDR system can accumulate quickly and results in an unacceptable position accuracy.

Pedestrian Dead Reckoning with Particle Filter for handheld smartphone
2016 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2016Commonly used Global Navigation Satellite Systems (GNSS) are inappropriate as Location Based Services (LBS) in indoor environment. Therefore research teams are developing different systems, which can be used as a suitable alternative. One of options is to use Inertial Navigation System (INS) which consists of inertial sensors and mathematic procedures.

Pedestrian Dead Reckoning With Smartglasses and Smartwatch
IEEE Sensors Journal, 2016Wearable miniature inertial sensors have been widely used for pedestrian dead reckoning (PDR). Typical low-cost PDR systems use sensors attached to either the human trunk or feet. The recent emergence of smartglasses and smart watches provides an opportunity to use both types of wearable devices in position tracking.

A Study on Direction Estimation for Pedestrian Dead Reckoning
2014 Second International Symposium on Computing and Networking, 2014The concern with the location estimation techniques has been growing. One of them is a Dead-Reckoning (DR) technique which tracks the position by estimating relative movement. It is possible to estimate the relative movement which consists of the distance and direction. We can measure them by several sensors.

Method of pedestrian dead reckoning using speed recognition
2010 Ubiquitous Positioning Indoor Navigation and Location Based Service, 2010Accurate and robust ubiquitous localization is one of the most demanding challenges that the navigation research community faces currently. The GNSS offers a perfect solution for open sky environment, however, in GPS-denied or unfavourable environments, for example urban canyons or indoors, the traditional GNSS standalone solution cannot provide the ...

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), 2015This 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 ...

Quaternion Vector Based Pedestrian Dead-Reckoning with Smartphones
2019 27th Signal Processing and Communications Applications Conference (SIU), 2019Global Positioning System (GPS) is frequently used for location determination in military and civil aviation sector, vehicles, smartphones etc. However, when satellite signal is weak or there is not any signal to connect and also for indoor navigation problems, an alternative solution is needed for location estimation.

Padati: A Robust Pedestrian Dead Reckoning System on Smartphones
2012 IEEE 11th International Conference on Trust, Security and Privacy in Computing and Communications, 2012Location based services are proving to be the next driving factors for growth in smartphones. While GPS solves the problem of accurate localization in outdoor environments, indoor localization is still an area of active research. Emergence of new generation smartphones with low cost sensors, have provided an effective way of indoor localization by ...
