Abstract
(EN) In the present invention, an image of a subject captured by a camera and sensor output indicating the spatial position of the subject as detected by a ranging sensor are acquired. The image and the spatial position of the subject are recorded in time series. It is determined whether or the spatial position of a tracking point on the subject at a second time overlaps a space including the trajectory history of the tracking point within a drawing determination time period that is based on a first time preceding the second time. If the determination is affirmative, displayed on a display is a virtual reality object comprising a marker drawn on spatial positions which have been passed through by the trajectory history and/or the spatial positions of the tracking point from the second time to a time at which a drawing stop condition is satisfied after the second time.
(FR) Dans la présente invention, une image d'un sujet capturée par un appareil de prise de vues et une sortie de capteur indiquant la position spatiale du sujet telle que détectée par un capteur de télémétrie sont acquises. L'image et la position spatiale du sujet sont enregistrées en série chronologique. Il est déterminé si la position spatiale d'un point de suivi sur le sujet à un second moment chevauche un espace comprenant l'historique de trajectoire du point de suivi dans une période de temps de détermination de dessin qui est basée sur un premier moment précédant le second moment. Si la détermination est affirmative, est affiché sur une unité d'affichage un objet de réalité virtuelle comprenant un marqueur dessiné sur des positions spatiales qui ont été passées par l'historique de trajectoire et/ou les positions spatiales du point de suivi du second moment à un moment auquel une condition d'arrêt de dessin est satisfaite après le second moment.
