Abstract :
In this paper, the vision regulation of a quadrotor is introduced. The objective of the regulation is to maintain the vehicle in a desired and constant position. The proposed strategy consists in three steps: 1) a camera is employed as a retro to obtain the position, 2) the optical flow of the Lucas and Kanade method is applied to obtain the linear velocity, 3) the position and velocity are employed by a proportional integral derivative control (PID) with nested saturation for the quadrotor regulation. In addition, the comparison between the monocular and stereo visions is showed.
