    Abstract: The general field of the invention is that of systems for detecting the posture of a mobile object. The systems according to the invention comprise a fixed electro-optical device comprising an emission source and a photosensitive sensor. The optical corner cube is arranged on the mobile object. The entry face of the corner cube has a predetermined geometry, the light coming from the source and reflected back by the corner cube forming a luminous contour on the matrix sensor. The fixed electro-optical device comprises an optical element with a known shape and location, which is placed in the vicinity of the said source and is arranged so as to form a dark zone in the central part of the luminous contour. The detection system comprises analysis means determining the position and the orientation of the mobile object from knowledge of the vanishing points of the luminous contour and the position and shape of the dark zone.

    Abstract: The invention relates to a method for verifying a character to be displayed on a screen, compared to a reference character. The character to be displayed and the reference character each comprise at least several characteristic points. The method comprises: a) determining a barycenter of the characteristic points of the character to be displayed, b) computing geometric coordinates of each characteristic point of the character to be displayed in a coordinate system centered on the determined barycenter, and c) computing a deviation between the character to be displayed and the reference character, as a function of the geometric coordinates computed for the character to be displayed and predetermined geometric coordinates for the reference character. The character to be displayed is considered correct only if the computed deviation is below the predetermined threshold.

    Abstract: The general field of the invention is that of systems for detecting the posture of a mobile object in space. The system according to the invention comprises an electro-optical device comprising a light source, a photoreceptor and means of analysis, and a retro-reflecting cube corner disposed on the mobile object. The cube corner comprises a mask disposed on its entry face. The source emits a parallel or almost-parallel pencil beam. The electro-optical device comprises means for deviating, about a fixed point, the said pencil beam of light by an angle varying as a function of time. The photoreceptor is configured for receiving the pencil beam of light retro-reflected by the cube corner. The means of analysis are configured in such a manner as to determine, based on the signal coming from the photoreceptor, the position of a number of points representative of the borders of the mask and, using this positional information, the posture of the cube corner in space.
