Improving Optical Flow Sensor Using a Gimbal for Quadrotor Navigation in GPS-Denied Environment
This paper proposes a new sensor using optical flow to stabilize a quadrotor when a GPS signal is not available. Normally, optical flow varies with the attitude of the aerial vehicle. This produces positive feedback on the attitude control that destabilizes the orientation of the vehicle. To avoid t...
