Robust Nonlinear Fusion of Inertial and Visual Data for position, velocity and attitude estimation of UAV

Cheviron, Thibault; Hamel, Tarek; Mahony, Robert; Baldwin, Grant

Description

This paper presents a coupled observer that uses accelerometer, gyrometer and vision sensors to provide estimates of pose and linear velocity for an aerial robotic vehicle. The observer is based on a non-linear complimentary filter framework and incorporates adaptive estimates of measurement bias in gyrometers and accelerometers commonly encountered in low-cost inertial measurement systems. Asymptotic stability of the observer estimates is proved as well as bounded energy of the observer error...[Show more]
