Title:
複数の製造物体のインライン寸法制御のための方法及び設備
Document Type and Number:
Japanese Patent JP7323517
Kind Code:
B2
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.
