| abstract |
The invention relates to a method and installation for automatically measuring linear dimensions of manufactured objects (2) of a run comprising: - arranging at least one X-ray focal point (Fj) on a given base line parallel to the rectilinear trajectory of movement of the objects and providing one or more image sensors (Ci); - acquiring, for each object over the course of its movement, a set of one-dimensional images comprising, for a number (NK) of distinct sectional planes (Pk) containing the base line, a number (NP) of said images obtained in at least three different directions of projection (Dijk) in the sectional plane; - for each object, and for each distinct sectional plane (Pk), determining, on the basis of the obtained images, a delineation of the object in the sectional plane (Pk) in question. |
