Recursive Bayesian Initialization of Localization Based on Ranging and Dead Reckoning
, 2013 The initialization of the state estimation in a localization scenario based on ranging and dead reckoning is studied. Specifically, we start with a cooperative localization setup and consider the problem of recursively arriving at a uni-modal state ...

A Multi-Mode PDR Perception and Positioning System Assisted by Map Matching and Particle Filtering
ISPRS International Journal of Geo-Information, 2020 Currently, pedestrian dead reckoning (PDR) is widely used in indoor positioning. Since there are restrictions on a device’s pose in the procedure of using a smartphone to perform the PDR algorithm, this study proposes a novel heading estimation ...
