Double Coupling Between Inertial Sensors and Visual Odometry in Multicopters

Abstract

This article presents a system for determining the position and orientation of unmanned aerial vehicles. The system has two hardware layers coupled in both directions. One layer stabilizes the vehicle while the other determines lateral displacements. The two-directional coupling between layers allows the system to minimize estimation errors. The proposed implementation is evaluated on real hardware and evaluation results show that a real time implementation is feasible.
