Title (EN) DEPTH SENSOR AIDED ESTIMATION OF VIRTUAL REALITY ENVIRONMENT BOUNDARIES
(FR) ESTIMATION ASSISTÉE PAR CAPTEUR DE PROFONDEUR DE LIMITES D'ENVIRONNEMENT DE RÉALITÉ VIRTUELLE
Abstract:
(EN) A method for depth sensor aided estimation of virtual reality environment boundaries includes generating depth data (132) at a depth sensor (118) of an electronic device (100) based on a local environment (112) proximate the electronic device. A set of initial boundary data (508, 510, 512, 514) is estimated based on the depth data, wherein the set of initial boundary data defines an exterior boundary of a virtual bounded floor plan (800). The virtual bounded floor plan is generated based at least in part on the set of initial boundary data. Additionally, a relative pose of the electronic device within the virtual bounded floor plan is determined and a collision warning (1104) is displayed on a display of the electronic device based on the relative pose.
(FR) L’invention concerne un procédé d'estimation assistée par capteur de profondeur de limites d'environnement de réalité virtuelle qui consiste à générer des données de profondeur (132) au niveau d'un capteur de profondeur (118) d'un dispositif électronique (100) sur la base d'un environnement local (112) à proximité du dispositif électronique. Un ensemble de données de limite initiale (508, 510, 512, 514) est estimé sur la base des données de profondeur, l'ensemble de données de limite initiale définissant une limite extérieure d'un plan de sol délimité virtuel (800). Le plan de sol délimité virtuel est généré sur la base, au moins en partie, de l'ensemble de données de limite initiale. De plus, une pose relative du dispositif électronique à l'intérieur du plan de sol limité virtuel est déterminée et un avertissement de collision (1104) est affiché sur un affichage du dispositif électronique sur la base de la pose relative.
