Abstract: The invention concerns a method for measuring the dimensions of empty glass containers (2) consisting in: selecting at least one region to be inspected of the container, transporting the containers, positioning, on either side of the region to be inspected, at least one focus of an X-ray generator tube and image sensors, acquiring, using image sensors, for each container during its displacement, at least three radiographic images of the inspected region, analyzing the at least three radiographic images so as to determine the three-dimensional coordinates of a set of points to deduce at least one inner diameter of the neck and/or one thickness of the body.

Abstract: A method of determining the capacity of containers (1) comprises using an X-ray computed-tomography apparatus (10) to acquire a plurality of X-ray images (I) of the container at different projection angles. The X-ray images are analyzed in order to construct a model of the container from the X-ray images, determine the inside surface of the digital model of the container, position a filling level plane on the digital model of the container parallel to the support surface and at a nominal distance from the top of the digital model of the container, and measure by calculation the inside volume of the digital model of the container as defined by the inside surface of the digital model and by the filling level plane, the measurement being the filling capacity of the container.

Abstract: An inspection device comprises movable equipment (6) driven relative to a stand (7) and fitted with at least one inspection gauge (14, 15). The device also includes a measurement system (30) comprising a contactless transceiver system (30a) for emitting and receiving a light beam (F) along a path in which there is arranged a target (30b) that is securely mounted to the first inspection gauge, the transceiver system being secured to the stand, and delivering measurements continuously of the position of the first inspection gauge relative to the stand (7). A processor unit (31) is provided that means for detecting when the measurements of the position of the inspection gauge delivered by the transceiver system (30a) cease varying, in order to determine that contact has occurred between the inspection gauge and the container.

Abstract: A measurement method comprises acquiring, using image sensors (Cji) for each object during its displacement, at least three radiographic images of the region to be inspected. The images are obtained from at least three radiographic projections of the region to be inspected, the directions of projection (Dji) of which are different from each other. A computer system is provided with an a priori geometric model of the region to be inspected for the series of objects. Using the computer system and considering a constant attenuation coefficient and, from the a priori geometric model, at least three radiographic images of the region to be inspected, a digital geometric model of the region to be inspected is determined. For each object of the series, from the digital geometric model of the region to be inspected, at least one linear dimension measurement of the region to be inspected is determined.

Abstract: A method of inspecting containers (3) moving between a linear camera and a light source (7) presents continuous variation of light intensity with a periodic pattern (71) along at least one variation direction (D). According to the method, for each movement increment of the container, a sequence of N successive image lines of the container is acquired cyclically so that for each image line; the container (3) is illuminated by the light source (7); the image line of the container is acquired; and the periodic pattern (71) is shifted for the next line along the variation direction (D). For each increment of the container (3), at least one phase image line is calculated; and the phase image lines (LP(k)) are analyzed.

Abstract: The invention relates to a method and an installation for automatically measuring linear dimensions of manufactured objects (2) of a series comprising:



the disposition of at least one focal point (Fj) of X-rays, on a same base straight line parallel to the rectilinear trajectory of displacement of the objects and of one or several image sensors (Ci);
the acquisition, for each object during its displacement, of a set of one-dimensional images comprising, for a number (NK) of distinct section planes (Pk) containing the base straight line, a number (NP) of said images obtained along at least three different directions of projection (Dijk) in the section plane;
for each object, and for each distinct section plane (Pk), the determination, from the images obtained, of a delineation of the object in the considered section plane (Pk).

Abstract: An inspection line comprises: at a finish inspection station, a finish inspection installation capable of detecting without contact, by light rays, check-type defects in the neck of the containers; at a base inspection station, a base inspection installation capable of detecting without contact, by light rays, check-type defects in the base of the containers; and at a radiographic measuring station, a radiographic installation for automatically measuring linear dimensions of at least one region to be inspected of containers. The three installations are each arranged at stations distinct from each other along a trajectory of displacement of the containers. In each installation, a section of the transport device ensures, in the inspection area of the installation, the transport of the containers along a rectilinear portion of the trajectory (T) in a horizontal conveying plane (Pc) perpendicular to the central axis of the containers.
