Fifteen Years of Progress at Zero Velocity: A Review

Johan Wahlström, Isaac Skog

Fifteen years have passed since the publication of Foxlin's seminal paper "Pedestrian tracking with shoe-mounted inertial sensors". In addition to popularizing the zero-velocity up…

FootSLAM meets Adaptive Thresholding

Johan Wahlstrom, Andrew Markham, Niki Trigoni

Calibration of the zero-velocity detection threshold is an essential prerequisite for zero-velocity-aided inertial navigation. However, the literature is lacking a self-contained c…

Sensor Fusion for Magneto-Inductive Navigation

Johan Wahlström, Manon Kok, Pedro Porto Buarque de Gusmao +3

Magneto-inductive navigation is an inexpensive and easily deployable solution to many of today's navigation problems. By utilizing very low frequency magnetic fields, magneto-induc…

DeepTIO: A Deep Thermal-Inertial Odometry with Visual Hallucination

Muhamad Risqi U. Saputra, Pedro P. B. de Gusmao, Chris Xiaoxuan Lu +7

Visual odometry shows excellent performance in a wide range of environments. However, in visually-denied scenarios (e.g. heavy smoke or darkness), pose estimates degrade or even fa…

Zero-Velocity Detection - A Bayesian Approach to Adaptive Thresholding

Johan Wahlström, Isaac Skog, Fredrik Gustafsson +2

A Bayesian zero-velocity detector for foot-mounted inertial navigation systems is presented. The detector extends existing zero-velocity detectors based on the likelihood-ratio tes…
