Method to determine a direction and amplitude of a current velocity estimate of a moving device

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod

A new method for the estimation of ego-motion (the direction and amplitude of the velocity) of a mobile device comprising optic-flow and inertial sensors (hereinafter the apparatus). The velocity is expressed in the apparatus's reference frame, which is mo ...
