Title (EN) SPECULAR REFLECTION REMOVAL IN TIME-OF-FLIGHT CAMERA APPARATUS
(FR) SUPPRESSION DE RÉFLEXION SPÉCULAIRE DANS UN APPAREIL DE CAMÉRA À TEMPS DE VOL
Abstract:
(EN) A method for facilitating removal of specular reflection noise from light data can include illuminating, using an illumination unit, a target with a light source. The illumination unit is configured to project light with a spatial light pattern onto the target. The method can also include acquiring, with a sensor unit, light data that is reflected from the target. The light data may comprise a directly reflected spatial light pattern and a specular reflected spatial light pattern. The directly reflected spatial light pattern and the specular reflected spatial light pattern comprise at least one spatial distinction that distinguishes the directly reflected spatial light pattern from the specular reflected spatial light pattern. The method can further comprise processing the light data to distinguish the directly reflected spatial light pattern from the specular reflected spatial light pattern based upon the at least one spatial distinction.
(FR) L'invention concerne un procédé pour faciliter la suppression d'un bruit de réflexion spéculaire provenant de données de lumière, qui peut consister à éclairer, à l'aide d'une unité d'éclairage, d'une cible avec une source de lumière. L'unité d'éclairage est configurée pour projeter une lumière ayant un motif de lumière spatial sur la cible. Le procédé peut également consister à acquérir, à l'aide d'une unité de capteur, des données de lumière qui sont réfléchies par la cible. Les données de lumière peuvent comprendre un motif de lumière spatial directement réfléchi et un motif de lumière spatial réfléchi de façon spéculaire. Le motif de lumière spatial directement réfléchi et le motif de lumière spatial réfléchi de façon spéculaire comprennent au moins une distinction spatiale qui distingue le motif de lumière spatial directement réfléchi du motif de lumière spatial réfléchi de façon spéculaire. Le procédé peut en outre consister à traiter les données de lumière pour distinguer le motif de lumière spatial directement réfléchi du motif de lumière spatial réfléchi de façon spéculaire sur la base de ladite au moins une distinction spatiale.
