Title (EN) TIME-OF-FLIGHT AUGMENTED STRUCTURED LIGHT RANGE-SENSOR
(FR) CAPTEUR DE PLAGE DE LUMIÈRE STRUCTURÉE AUGMENTÉE DE TEMPS DE VOL
Abstract:
(EN) The technology described herein is a depth camera that uses structured light and modulated light to produce a depth image. The modulated and structured light allows a time-of-flight depth to be calculated for each unit (e.g., a single dot) of the reflected structured light image captured by the depth camera's image sensor. The time-of-flight depth can be used to accurately identify each unit of the reflected structured light image. Once each unit of the reflected structured light image is identified, a structured light triangulation algorithm can be used to calculate a depth for each unit of the reflected structured light image. The present technology also allows a confidence score to be generated for the assigned depths within the depth image by comparing the structured light depth for each unit to the TOF depth for each unit.
(FR) La présente invention concerne une technologie comprenant une caméra de profondeur qui utilise une lumière structurée et une lumière modulée pour produire une image de profondeur. La lumière modulée et structurée permet de calculer une profondeur de temps de vol pour chaque unité (par exemple, un point unique) de l'image de lumière structurée réfléchie capturée par le capteur d'image de la caméra de profondeur. La profondeur de temps de vol peut être utilisée pour identifier avec précision chaque unité de l'image de lumière structurée réfléchie. Une fois que chaque unité de l'image de lumière structurée réfléchie est identifiée, un algorithme de triangulation de lumière structurée peut être utilisé pour calculer une profondeur pour chaque unité de l'image de lumière structurée réfléchie. La présente technologie permet également de générer un score de confiance des profondeurs attribuées dans l'image de profondeur par la comparaison de la profondeur de lumière structurée pour chaque unité avec la profondeur de TOF pour chaque unité.
