Title (EN) TIME OF FLIGHT DEPTH CAMERA
(FR) CAMÉRA DE PROFONDEUR À TEMPS DE VOL
Abstract:
(EN) A method for operating a time of flight, TOF, depth camera is provided. The method includes, using an image processing module (110), interpolating an updated timing delay calibration for each of a plurality of pixel sensors (122) based at least on an updated set of modulation frequency and duty cycle calibration combinations received by the image processing module, the plurality of pixel sensors coupled to a timing clock, and receiving light generated by a light source (116) and reflected in a 3-dimensional environment, the updated set of modulation frequency and duty cycle calibration combinations replacing the corresponding factory-preloaded timing delay calibrations. The method further includes applying the updated timing delay calibrations to pixel data corresponding to each of the plurality of the pixel sensors (122) to generate a depth map of the 3- dimensional environment.
(FR) L'invention concerne un procédé d'exploitation d'une caméra de profondeur à temps de vol (TOF). Le procédé comprend, au moyen d'un module de traitement d'image (110), l'interpolation d'un étalonnage de délai de temporisation mis à jour pour chacun parmi une pluralité de capteurs de pixel (122) au moins sur la base d'un ensemble mis à jour de combinaisons d'étalonnage de fréquence de modulation et de cycle de service reçues par le module de traitement d'image, de la pluralité de capteurs de pixel couplés à une horloge de temporisation, et de la réception de la lumière de réception générée par une source lumineuse (116) et réfléchie dans un environnement tridimensionnel, l'ensemble mis à jour de combinaisons d'étalonnage de fréquence de modulation et de cycle de service remplaçant les étalonnages de délai de temporisation correspondants préchargés en usine. Le procédé comprend en outre l'application des étalonnages de délai de temporisation mis à jour aux données de pixel correspondant à chacun parmi la pluralité de capteurs de pixel (122) pour générer une carte de profondeur de l'environnement tridimensionnel.
