Multi-Source Adaptive Selection and Fusion for Pedestrian Dead Reckoning

IEEE/CAA Journal of Automatica Sinica, 2022
Accurate multi-source fusion is based on the reliability, quantity, and fusion mode of the sources. The problem of selecting the optimal set for participating in the fusion process is nondeterministic-polynomial-time-hard and is neither sub-modular nor ...

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.

A Pedestrian Dead Reckoning Method with Heuristic Motion Direction Estimation for Multiple Gaits

International Conference on Indoor Positioning and Indoor Navigation
Pedestrian dead reckoning (PDR) based on inertial measurement units (IMU) is widely applied due to its robustness and low requirements for wear. However, traditional PDR methods only estimate forward motion, and cannot accurately position in backward and

Deep LSTM-Based Multimode Pedestrian Dead Reckoning System for Indoor Localization

International Conference on Electronics, Information and Communications, 2022
We propose a multimode pedestrian dead reckoning (PDR) system using a recurrent neural network. We adopt a long short-term memory (LSTM) layer to extract latent features from the sensor data.

Pedestrian dead reckoning towards indoor location based applications

2011 8th International Conference on Electrical Engineering, Computing Science and Automatic Control, 2011
In this work a pedestrian dead reckoning (PDR) algorithm is proposed in which 3-axis inertial sensors (accelerometer and gyroscope) are used. This work consists of the first stage of a project, in which inertial sensors will be integrated with a global position system (GPS) sensor and a camera in a hand-held platform which performs monocular ...

Learning-Based Stance Phase Detection and Multisensor Data Fusion for ZUPT-Aided Pedestrian Dead Reckoning System

IEEE Internet of Things Journal
In a closed environment lacking global positioning system (GPS) signals, how to achieve accurate navigation and positioning is a very challenging task. Zero velocity update (ZUPT) is a highly effective foot-mounted inertial pedestrian navigation systems ...

Pedestrian dead reckoning with waist-worn inertial sensors

2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings, 2012
We present a waist-worn personal navigation system based on inertial measurement units. The device makes use of the human bipedal pattern to reduce position error. We describe improved algorithms, based on detailed description of the heel strike biomechanics and its translation to accelerations of the body waits, to estimate the periods of zero ...

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 ...

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.
