Abstract

L'invention concerne un procédé de génération d'une image d'une vue autour d'un véhicule, qui consiste à estimer des coordonnées de polygone dans une image de distorsion obtenue par une caméra grand angle, et à cartographier en polygone les coordonnées de polygone estimées en une image standard. A cette fin, le procédé de génération d'une image d'une vue autour d'un véhicule consiste à corriger la distorsion radiale d'une image obtenue à partir de plusieurs caméras grand angle afin de générer une image de la vue, et comprend les étapes suivantes : définir une valeur de coordonnées standard par rapport à chaque point d'intersection d'un motif de grille standard et générer une image standard divisée par plusieurs polygones standards ayant des sommets standards (A', B', C') par rapport à une image de motif de grille ; capturer un motif en échiquier en utilisant plusieurs caméras grand angle afin d'obtenir chaque image de distorsion ; détecter le bord du motif d'échiquier dans chaque image de distorsion ; estimer plusieurs points de correction en utilisant des quantités de changement de répartition de luminosité dans une direction verticale et dans une direction parallèle pendant le suivi de ligne le long de la zone de bord détectée, et choisir un ordre de correction pour les points de correction estimés ; diviser chaque image de distorsion en plusieurs polygones de distorsion ayant des sommets de correction (A, B, C) ; cartographier chaque coordonnée de pixel de l'image de distorsion sur une coordonnée standard afin que le polygone de distorsion corresponde à un polygone standard en fonction de l'ordre de correction afin d'obtenir chaque image de correction ; et générer une image de la vue autour du véhicule en combinant chaque image de correction avec une image en plan du véhicule.
