DEVICE AND METHOD FOR INERTIAL/VIDEO HYBRIDIZATION

The invention relates to an inertial/video hybridisation device () intended to be mounted on a carrier (), the device comprising: a camera () configured to acquire a first image showing a predetermined landmark () attached to the carrier (), a processing unit () configured to estimate a velocity of the carrier () from the acquired first image, with a view to hybridising the estimated velocity with inertial data relating to the carrier () produced by an inertial unit (), locating a position of the landmark () in the first acquired image, calculating a deviation between the located position and a reference position of the landmark (), comparing the calculated deviation with a predetermined threshold, and signalling an alert when the calculated deviation is greater than the predetermined threshold.
