A method and apparatus for testing luggage screening equipment operators is provides. A sequence of images of contents of luggage items derived from a device that scans the luggage items with penetrating radiation are received. The image generation device is characterized by introducing a certain distortion into these images of contents of luggage items. A display device is caused to display images derived from this sequence of images. Occasionally, the display device is caused to show a simulated threat in a luggage item by displaying a combined image derived based at least in part on an image in the sequence of images and a distorted threat image. The distorted threat image was derived by applying a distortion insertion process to a reference threat image wherein the distortion insertion process tends to approximate the certain distortion introduced in the images of contents of luggage items by the device that scans the luggage items with penetrating radiation.

L'invention concerne un procédé et un dispositif de test d'utilisateurs d'équipements de contrôle des bagages. Une séquence d'images de contenus de bagages dérivée d'un dispositif balayant les bagages avec un rayonnement pénétrant est reçue. Le dispositif de production d'images est caractérisé par l'introduction d'une certaine distorsion dans ces images de contenus de bagages. Un dispositif d'affichage affiche les images dérivées de cette séquence d'images. Le dispositif d'affichage peut occasionnellement être amené à afficher une menace simulée dans un bagage par affichage d'une image combinée dérivée au moins partiellement sur la base d'une image de la séquence d'images et d'une image de menace distordue. L'image de menace distordue est dérivée par application d'un processus d'insertion de distorsion à une image de menace de référence, le processus d'insertion de distorsion tendant à approcher la distorsion introduite dans les images de contenus de bagages par le dispositif balayant les bagages avec un rayonnement pénétrant.
