Abstract
L’invention décrit un procédé de calibrage d’une caméra plénoptique, comprenant une étape S1 d’acquisition d’un point objet réel (P_obj_r) d’une mire de calibrage par la caméra plénoptique, une étape S6 de détermination d’un ensemble de rayons lumineux objets (60), à partir de rayons lumineux images (50) associés et de paramètres de projection (Par_Proj) d’un modèle de projection de la caméra plénoptique, une étape S7 de détermination d’un point objet théorique (P_obj_th) associé au point objet réel (P_obj_r), le point objet théorique (P_obj_th) correspondant à un barycentre de l’ensemble des intersections des rayons lumineux objets (60) avec la mire de calibrage, et une étape S8 de calcul d’une erreur de calibrage (Δcal) en fonction d’une position du point objet théorique (P_obj_th) et de la position du point objet réel (P_obj_r).
