Title (EN) SYSTEM AND METHOD FOR RECTIFYING A WIDE-ANGLE IMAGE
(FR) SYSTÈME ET PROCÉDÉ DE CORRECTION D'UNE IMAGE GRAND ANGLE
Abstract:
(EN) System and method can rectify a wide-angle image captured using a wide-angle lens. The system can obtain a projection model for the wide-angle lens, wherein the projection model corresponds the wide-angle image with a plurality of target image portions in a target image. Furthermore, the system can determine, based on the projection model, a plurality of reference pixels in the wide-angle image for a target pixel in the plurality of target image portions. Then, the system can calculate one or more pixel values for said target pixel based on the plurality of reference pixels in the wide-angle image.
(FR) Le système et le procédé permettent de corriger une image grand angle capturée à l'aide d'une lentille grand angle. Le système peut obtenir un modèle de projection pour la lentille grand angle, le modèle de projection correspondant à l'image grand angle avec une pluralité de parties d'image cibles dans une image cible. En outre, le système peut déterminer, sur la base du modèle de projection, une pluralité de pixels de référence dans l'image grand angle pour un pixel cible dans la pluralité de parties d'image cible. Ensuite, le système peut calculer une ou plusieurs valeurs de pixel pour ledit pixel cible sur la base de la pluralité de pixels de référence dans l'image grand angle.
