Abstract

L'invention concerne un capteur destiné à un véhicule, logé de façon mobile sur celui-ci. Ledit capteur comporte au moins un capteur d'image (4) et/ou le capteur est conçu pour le domaine spectral visible ou infrarouge. Une source lumineuse (3), notamment une DEL, est prévue dans une position fixe par rapport au capteur ou dans le capteur. Ladite source lumineuse émet un faisceau de référence (11) dans le domaine spectral visible et peut être activée pour l'orientation du capteur. Le capteur selon l'invention est particulièrement destiné à être employé dans des caméras et systèmes de LIDAR et RADAR montés dans des véhicules, l'ajustage étant réalisé au moyen d'un dispositif de réglage de phare habituel (9).
