Automated quality control and selection

A non-destructive inspection method for inline inspection of an object comprises moving an object in between a radiation source and an image detector and through a three-dimensional scanner field of view, imaging the object using the image detector to obtain a projection radiograph of an internal structure of the object, scanning an exterior surface of the object using the 3D scanner, fitting 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 a solid model of the surface model by taking a grey value distribution of a reference object into account, simulating a reference radiograph from the solid model and comparing the reference and projection radiographs to detect internal deviations of the object.
