Positioning Method of Pedestrian Dead Reckoning Based on Human Activity Recognition Assistance
International Conference on Indoor Positioning and Indoor Navigation, 2022Aiming at the problem that the traditional Pedestrian Dead Reckoning (PDR) cannot adapt to the reliable positioning of the target in different motion states, this paper designs and proposes a positioning method based on deep learning for Human Activity ...

A Pedestrian Dead Reckoning Method with Heuristic Motion Direction Estimation for Multiple Gaits
International Conference on Indoor Positioning and Indoor NavigationPedestrian 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

Multi-Source Adaptive Selection and Fusion for Pedestrian Dead Reckoning
IEEE/CAA Journal of Automatica Sinica, 2022Accurate 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), 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.

Deep LSTM-Based Multimode Pedestrian Dead Reckoning System for Indoor Localization
International Conference on Electronics, Information and Communications, 2022We 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, 2011In 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 ...

Doppler Shift Mitigation in Acoustic Positioning Based on Pedestrian Dead Reckoning for Smartphone
IEEE Transactions on Instrumentation and Measurement, 2021Acoustic localization is a viable solution for high-precision indoor positioning with current built-in smartphone sensors. However, the Doppler shift produces an additional error in the time difference of arrival (TDOA) estimation when the smartphone is ...

Pedestrian dead reckoning with waist-worn inertial sensors
2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings, 2012We 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 ...
