(FR) PROCÉDÉS ET APPAREIL DE MAILLAGE OPTIMISÉ DE CONTENU DE SURCAPTURE
Abstract
(EN)
Apparatus and methods for optimized stitching of overcapture content. In one embodiment, the optimized stitching of the overcapture content includes capturing the overcapture content; producing overlap bands associated with the captured overcapture content; downsampling the produced overlap bands; generating derivative images from the downsampled overlap bands; generating a cost map associated with the generated derivative images; determining shortest path information for the generated cost map; generating a warp file based on the determined shortest path information, the generated warp file being utilized for the optimized stitching of the overcapture content. Camera apparatus and a non-transitory computer-readable apparatus are also disclosed.

L'invention concerne un appareil et des procédés pour de maillage optimisé de contenu de surcapture. Dans un mode de réalisation, le maillage optimisé du contenu de surcapture consiste : à capturer le contenu de surcapture ; à produire des bandes de chevauchement associées au contenu de surcapture capturé ; à sous-échantillonner les bandes de chevauchement produites ; à générer des images dérivées à partir des bandes de chevauchement sous-échantillonnées ; à générer une carte de coût associée aux images dérivées générées ; à déterminer des informations de trajet le plus court pour la carte de coût générée ; à générer un fichier de chaîne sur la base des informations de trajet le plus court déterminées, le fichier de chaîne généré étant utilisé pour le maillage optimisé du contenu de surcapture. L'invention concerne également un appareil photographique et un appareil lisible par ordinateur non transitoire.
