Abstract

Une cible, comprenant une coque (100), un écran d'affichage (200) et une carte de circuit imprimé de commande (300). La carte de circuit imprimé de commande (300) est électriquement connectée à l'écran d'affichage (200) et sert à commander l'écran d'affichage (200), afin d'afficher un motif prédéfini, pour qu'un dispositif externe de détection acquière, par un appareil de collecte d'images, une image comportant le motif prédéfini et exécute, selon l'image, un processus correspondant de détection sur un véhicule à détecter. Le motif prédéfini que présente la cible n'est pas formé par une impression à l'encre, mais est plutôt formé par l'affichage de l'écran d'affichage (200) sous la commande de la carte de circuit imprimé de commande (300). L'inconvénient associé, affectant l'effet d'affichage du motif prédéfini à cause de la diffusion facilitée vers l'extérieur d'encre présente au bord du motif prédéfini, peut être efficacement évité. Un système d'alignement pour quatre roues et un procédé d'alignement pour quatre roues sont également divulgués.
