Title
(EN) MERGING WEBCAM SIGNALS FROM MULTIPLE CAMERAS
(FR) FUSION DE SIGNAUX WEBCAMÉRA PROVENANT DE MULTIPLES CAMÉRAS
Abstract
(EN) A system includes a camera (100a) for capturing a first panorama view. The system determines a first bearing (Bla, B2a, B3a) of a person (Ml, M2, M3) within the first panorama view, and a first gaze direction (G) of the person within the first panorama view. The system receives, from an external source (100b), a second panorama view, a second bearing (Bib, B2b, B3b) of the person within the second panorama view, and a second gaze direction of the person within the second panorama view. The system selects, by comparing the first gaze direction and the second gaze direction, a selected panorama view and a selected bearing of the person. The system forms a localized subscene video signal based on the selected panorama view along the selected bearing of the person. The system generates a stage view signal based on the localized subscene video signal, and composites a composited signal comprising the stage view signal.
(FR) Selon la présente invention, un système comprend une caméra pour capturer une première vue panoramique. Le système détermine une première posture d'une personne dans la première vue panoramique et une première direction du regard de la personne dans la première vue panoramique. Le système reçoit, en provenance d'une source externe, une seconde vue panoramique, une seconde posture de la personne dans la seconde vue panoramique, et une seconde direction du regard de la personne dans la seconde vue panoramique. Le système sélectionne, par comparaison de la première direction du regard et de la seconde direction du regard, une vue panoramique sélectionnée et une posture sélectionnée de la personne. Le système forme un signal vidéo de sous-scène localisée sur la base de la vue panoramique sélectionnée conjointement avec la posture sélectionnée de la personne. Le système génère un signal de vue de plateau sur la base du signal vidéo de sous-scène localisée, et compose un signal composite comprenant le signal de vue de plateau.
