A non-destructive inspection method for inline inspection of an object, the non-destructive inspection method comprising: - moving, using an inline transport system, an object, that is at least partially transparent to radiation of a predetermined radiation quality, along a predetermined path in between a stationary radiation source, for emitting radiation of said predetermined radiation quality, and a stationary image detector, and through a field of view of a three-dimensional scanner; - imaging said object using the image detector by detecting said radiation emitted by the radiation source and transmitted through said object to obtain a projection radiograph of an internal structure of said object; - scanning an exterior surface of said object using the three-dimensional scanner 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; - fitting, using a processor, a deformable shape model of said object to said point cloud to obtain a surface model of said exterior surface; - creating, using said processor, a solid model of said surface model by taking a grey value distribution of a reference object into account; - simulating, using said processor, a reference radiograph from said solid model; and - comparing, using said processor, said reference radiograph with said projection radiograph to detect and/or measure internal deviations of said object with respect to the reference object, wherein said step of creating the solid model and/or said step of simulating said reference radiograph takes a predetermined relative spatial configuration of said image detector, said radiation source and said three-dimensional scanner into account, wherein said three-dimensional scanner is a 3D scanner selected from the group consisting of a laser line scanner, multiple RGB cameras, an optical 3D scanner, a non-contact active scanner using light or ultrasound emissions, a time-of-flight 3D laser scanner, a triangulation-based 3D laser scanner, a conoscopic holographic laser scanner, a structured light 3D scanner, a modulated light 3D scanner, a stereoscopic optical imaging system, a photometric imaging system, a laser line in combination with an RGB camera system and a silhouette imaging 3D scanner, wherein said scanning of said exterior surface comprises generating a partial point cloud of said object, wherein said fitting comprises estimating the complete exterior surface and position of the object by fitting said shape model, wherein said creating of the solid model comprises filling in a volume defined by said surface model with said grey value distribution, said volume corresponding to the space coordinates of the object when imaged by the image detector, and wherein said simulating of said reference radiograph comprises simulating an imaging process of the solid model by forward projection using said predetermined spatial configuration of the image detector and radiation source in said space coordinates. - moving, using an inline transport system, an object, that is at least partially transparent to radiation of a predetermined radiation quality, along a predetermined path in between a stationary radiation source, for emitting radiation of said predetermined radiation quality, and a stationary image detector, and through a field of view of a three-dimensional scanner; - imaging said object using the image detector by detecting said radiation emitted by the radiation source and transmitted through said object to obtain a projection radiograph of an internal structure of said object; - scanning an exterior surface of said object using the three-dimensional scanner 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; - fitting, using a processor, a deformable shape model of said object to said point cloud to obtain a surface model of said exterior surface; - creating, using said processor, a solid model of said surface model by taking a grey value distribution of a reference object into account; - simulating, using said processor, a reference radiograph from said solid model; and - comparing, using said processor, said reference radiograph with said projection radiograph to detect and/or measure internal deviations of said object with respect to the reference object,
