Abstract

L’invention concerne un procédé de contrôle d’un dispositif lumineux (1) d’un véhicule automobile comprenant un ou plusieurs modules lumineux (3, 4), chaque module comprenant une pluralité de sources lumineuses (31, 41) et un dispositif optique (32, 42) agencés pour émettre un faisceau lumineux pixélisé (F3, F4) dans une zone d’émission prédéterminée (Z3, Z4), le procédé comportant les étapes suivantes : (E1) Réception d’une instruction d’émission (It) d’une fonction lumineuse pixélisée souhaitée ; (E2) Pour chacun des modules lumineux, création d’une image numérique (I3, I4) réalisant une portion de la fonction lumineuse pixélisée souhaitée dans un cadre (C3, C4) correspondant à la zone d’émission prédéterminée du module lumineux, l’image numérique étant indépendante des types de sources lumineuses et de dispositif optique du module lumineux ; (E3) Pour chacun des modules lumineux, correction de ladite image numérique créée en fonction des types de sources lumineuses et de dispositif optique du module lumineux ; et (E4) Pour chacun des modules lumineux, émission par le module lumineux d’un faisceau lumineux pixélisé dans la zone d’émission prédéterminée correspondant à l’image numérique corrigée (I3’, I4’). Figure à publier avec l’abrégé : Fig. 4
