Abstract
The present invention relates to a device for optically detecting position and/or attitude of an object (5) moving in a given travel range (4), said device comprising electro-optical sensors positioned on said object and distributed in groups, called clusters (6), analysis and computation means (2) making it possible to find the position and/or the attitude of said object, electronic image generation means (1) and optical projection means (1) comprising a display and a projection optic. The optical projection means emit, in a projection cone, a clear image (3) at any point of the travel range, the analysis of the signals received by the sensors of at least one cluster making it possible to identify the position and/or the attitude of the object in the frame of reference defined by the projection means, the latter consisting of a plane perpendicular to the projection axis, called image plane, and the projection axis.
