Abstract :
This work deals with the control by vision of the Gough-Stewart platform. For that, a central catadioptric camera is used to observe the platform legs. This allows to obtain a large field of view, and then avoids the occlusion problems observed when a classical perspective camera is used. The leg projections onto the catadioptric plane are used to determine their orientation in the camera frame. Finally, the computed orientations will be used in a visual servoing scheme of the platform effector.
