Title
(EN) PROCESS AND APPARATUS FOR THE CAPTURE OF PLENOPTIC IMAGES BETWEEN ARBITRARY PLANES
(FR) PROCÉDÉ ET APPAREIL POUR LA CAPTURE D'IMAGES PLÉNOPTIQUES ENTRE DES PLANS ARBITRAIRES
Abstract
(EN)
A process and an apparatus are described for the plenoptic capture of photographic or cinematographic images of an object or a 3D scene (10) of interest, both based on correlated light emitting source and correlation measurement, along the line of "Correlation Plenoptic Imaging" (CPI). A first image sensor (Dɑ) and a second image sensor (Db) detect images along a path of a first light beam (ɑ) and a second light beam (b), respectively. A processing unit (100) of the intensities detected by the synchronized image sensors (Dɑ, Db) is configured to retrieve the propagation direction of light by measuring spatio-temporal correlations between light intensities detected in the image planes of at least two arbitrary planes (Ρ', P"; D'b, D"a) chosen in the vicinity of the object or within the 3D scene (10).

L'invention concerne un procédé et un appareil pour la capture plénoptique d'images photographiques ou cinématographiques d'un objet ou d'une scène 3D (10) d'intérêt, les deux basées sur une source d'émission de lumière corrélée et d'une mesure de corrélation, le long de la ligne de "Imagerie Plénoptique de Corrélation" (CPI). Un premier capteur d'image (D ɑ ) et un second capteur d'image (D b ) détectent des images le long d'un trajet d'un premier faisceau lumineux (ɑ) et d'un second faisceau lumineux (b), respectivement. Une unité de traitement (100) des intensités détectées par les capteurs d'image synchronisés (D ɑ , D b ) est configurée pour récupérer la direction de propagation de la lumière par mesure de corrélations spatio-temporelles entre des intensités lumineuses détectées dans les plans d'image d'au moins deux plans arbitraires (Ρ', P"; D'b, D" a ) choisis au voisinage de l'objet ou à l'intérieur de la scène 3D (10).
