The VTOL vehicle is assumed to be equipped with a minimum sensor suite -i.e. a camera, altitude sensor and IMU-and to hover over a featured flat plane. This paper first presents a fast feature-based global motion estimation method, and then proposes a control strategy based on this method. Finally, experimental results using a quadrotor demonstrate the performance of the proposed control strategy and feature-based motion estimation.
