Automated quality control and selection

A non-destructive inspection system for inline inspection of an object, the non-destructive inspection system comprising:

• a radiation source and an image detector forming a radiographic imaging system for detecting radiation emitted by the radiation source and transmitted through an object that is at least partially transparent for said radiation, to provide a projection radiograph of an internal structure of said object;
• a three-dimensional scanner for scanning an exterior surface of said object to obtain three-dimensional scanning data of said object in the form of a point cloud representative of at least part of said exterior surface;
• an inline transport system for moving the object along a predetermined path in between the radiation source and the image detector and through a field of view of the three-dimensional scanner;
• and
• a processor adapted for:
• obtaining said projection radiograph from said image detector,
• obtaining said point cloud from said three-dimensional scanner,
• fitting a shape model of said object to said point cloud to obtain a surface model of said exterior surface,
• creating a solid model of said surface model by taking a grey value distribution of a reference object into account,
• simulating a reference radiograph from said solid model;
• and
• comparing said reference radiograph with said projection radiograph to detect and/or measure internal deviations of said object with respect to the reference object,
• wherein the processor is further adapted for creating said solid model and/or simulating said reference radiograph by taking a predetermined relative spatial configuration of said image detector, said radiation source and said three-dimensional scanner into account.
