Wearable indoor pedestrian dead reckoning system
Pervasive and Mobile Computing, 2010We introduce a wearable pedestrian indoor localization system with dynamic position correction. The system uniquely combines dead reckoning and fiducial marker-based localization schemes, exclusively using widely available, low end and low power consumer hardware components. The proposed system was tested with various walking patterns inside a building,

Waist mounted Pedestrian Dead-Reckoning system
2012 9th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2012This paper proposes a waist mounted PDR(Pedestrian Dead-Reckoning) algorithm using a low cost MEMS IMU(Inertial Measurement Unit). The PDR algorithm is consist of three algorithms which are step detection, step length estimation and heading estimation. The step detection is to detect a gait of pedestrian in walking.

Heading Estimation for Multimode Pedestrian Dead Reckoning
IEEE Sensors Journal, 2020The 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

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 ...

Effective integration algorithm for pedestrian dead reckoning
2018 Moscow Workshop on Electronic and Networking Technologies (MWENT), 2018Robust and reliable pedestrian navigation in GNSS (Global Navigation Satellite System) denied or hindered environments is still an actual problem. There is the range of different known solutions, one of which is to utilize MEMS (Microelectromechanical Systems) sensors and GNSS receiver measurements in integration algorithm.

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 ...
