Abstract: An apparatus and method for three-dimensional inspection of an object by X-rays. The apparatus includes an X-ray generator and a digital imaging device spaced from each other by a distance which defines a magnification by 1 on the imaging device. The apparatus also includes a means for moving the X-ray generator and identically the imaging device by unitary movements in two orthogonal directions. Each unitary movement corresponds to an integer number fraction of the side of the imaging device, and obtains, by successive shots after each unitary movement, a matrix set of sub-images overlapping in the plane of extension of the imaging device. Each sub-image has a center with coordinates in a plane of magnification equal to N. An image processing means performs magnification of each sub-image and determines a stretch factor enabling the coincidence of the sub-images representing all or part of a predefined element of interest.

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.
