Patent ID: 8810806

Claim:
System for detecting the position of a mobile object in space, comprising a fixed electro-optical device of known orientation, comprising at least a first transmission point source, image analysis means and a unit comprising an optical cube corner disposed on the mobile object, wherein: the input surface of the cube corner comprises a polygonal-shaped mask, each side of the polygon comprising a geometric marking to identify it, the image of the mask obtained by reflection on the surfaces of the cube corner being the intersection of the projection of the mask and the projection of its image by the cube corner in relation to the center of the cube corner; the fixed electro-optical device comprises optical means for implementing a luminous shape in perspective in a first recording plane and a second luminous shape in perspective in a second recording plane optically offset from the first recording plane, photosensitive means being disposed in said recording planes; and the image analysis means comprising means for determining the two first vanishing points of the first luminous shape in the first recording plane and the two second vanishing points of the second luminous shape in the second recording plane, the knowledge of said four vanishing points enabling the position and orientation of the optical cube corner in relation to the fixed electro-optical device to be determined.
