Strap-down Pedestrian Dead-Reckoning system

2011 International Conference on Indoor Positioning and Indoor Navigation, 2011
This 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.

Pedestrian Dead Reckoning with Particle Filter for handheld smartphone

2016 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2016
Commonly 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.

A Study on Direction Estimation for Pedestrian Dead Reckoning

2014 Second International Symposium on Computing and Networking, 2014
The 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, 2010
Accurate 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 ...

Pedestrian Dead Reckoning With Smartglasses and Smartwatch

IEEE Sensors Journal, 2016
Wearable 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.

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 ...

Quaternion Vector Based Pedestrian Dead-Reckoning with Smartphones

2019 27th Signal Processing and Communications Applications Conference (SIU), 2019
Global 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, 2012
Location 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 ...

Heading Estimation for Multimode Pedestrian Dead Reckoning

IEEE Sensors Journal, 2020
The flexible carrying mode of smartphone brings challenge for Pedestrian Dead Reckoning (PDR) especially for heading estimation with build-in sensors. This paper focuses on POCKET mode and SWING mode and analyzes the correlation between smartphone's rotational motion and pedestrian's walking cycle states and walking direction. Based on the analysis, we

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 ...
