AUTOMATED QUALITY CONTROL AND SELECTION

摘要

The present invention relates to a non-destructive inspection method (10) for inline inspection of an object, and a related system. The method comprises moving (11) an object in between a radiation source and an image detector and through a three-dimensional scanner field of view, imaging (12) the object using the image detector to obtain a projection radiograph of an internal structure of the object, scanning (13) an exterior surface of the object using the 3D scanner, fitting (14) a shape model of the object to a point cloud provided by the 3D scanner to obtain a surface model of the exterior surface, creating (15) a solid model of the surface model by taking a grey value distribution of a reference object into account, simulating (16) a reference radiograph from the solid model and comparing (17) the reference and projection radiographs to detect internal deviations of the object.
