- A method for measuring dimensions of at least one region to be inspected of empty glass containers of a series each having a wall forming a neck and a body and delimited by an inner surface and an outer surface, the method consists in: - selecting at least one region to be inspected comprising at least part of the neck and/or part of the container body; - transporting the containers placed on their bottom in a conveying plane ( Pc ) along a flat trajectory with a direction materialized by a displacement vector ( T ), these containers generating a conveying volume ( Vt ) during their displacement; - positioning, on either side of the region to be inspected, at least one focus ( Fj ) of an X-ray generator tube and X-ray sensitive image sensors ( Cji ) and each exposed to X-rays obtained from an associated focus ( Fj ), these X-rays having passed through at least the region to be inspected producing on each image sensor a radiographic projection in a projection direction ( Dji ); - acquiring using image sensors ( Cji ) for each container during its displacement, at least three radiographic images of the inspected region, obtained from at least three radiographic projections of the region to be inspected, the projection directions of which are different; - constructing, using a computer system, a digital geometric model of the region to be inspected for each container, from at least three radiographic images, said geometric model containing the three-dimensional coordinates of a set of points, calculated from the at least three radiographic images, this set of points belonging to the inner and/or outer surface of the wall of the container, with at least two points located in a plane not orthogonal to one of the said projection directions ( Dji ), - deducing at least one inner diameter of the neck measured on the model in a plane not orthogonal to one of the said projection directions ( Dji ), and/or at least one thickness of the wall of the body measured on the model in a plane not orthogonal to one of the said projection directions ( Dji ). - selecting at least one region to be inspected comprising at least part of the neck and/or part of the container body; - transporting the containers placed on their bottom in a conveying plane ( Pc ) along a flat trajectory with a direction materialized by a displacement vector ( T ), these containers generating a conveying volume ( Vt ) during their displacement; - positioning, on either side of the region to be inspected, at least one focus ( Fj ) of an X-ray generator tube and X-ray sensitive image sensors ( Cji ) and each exposed to X-rays obtained from an associated focus ( Fj ), these X-rays having passed through at least the region to be inspected producing on each image sensor a radiographic projection in a projection direction ( Dji ); - acquiring using image sensors ( Cji ) for each container during its displacement, at least three radiographic images of the inspected region, obtained from at least three radiographic projections of the region to be inspected, the projection directions of which are different; - constructing, using a computer system, a digital geometric model of the region to be inspected for each container, from at least three radiographic images, said geometric model containing the three-dimensional coordinates of a set of points, calculated from the at least three radiographic images, this set of points belonging to the inner and/or outer surface of the wall of the container, with at least two points located in a plane not orthogonal to one of the said projection directions ( Dji ), - deducing at least one inner diameter of the neck measured on the model in a plane not orthogonal to one of the said projection directions ( Dji ), and/or at least one thickness of the wall of the body measured on the model in a plane not orthogonal to one of the said projection directions ( Dji ). <EOS>
