Title: (DE) SYSTEME UND VERFAHREN FÜR ERWEITERTE REALITÄT
(EN) SYSTEMS AND METHODS FOR AUGMENTED REALITY
(FR) SYSTÈMES ET PROCÉDÉS POUR RÉALITÉ AUGMENTÉE
Abstract:
(EN) An augmented reality display system includes an electromagnetic field emitter to emit a known magnetic field in a known coordinate system. The system also includes an electromagnetic sensor to measure a parameter related to a magnetic flux at the electromagnetic sensor resulting from the known magnetic field. The system further includes a depth sensor to measure a distance in the known coordinate system. Moreover, the system includes a controller to determine pose information of the electromagnetic sensor relative to the electromagnetic field emitter in the known coordinate system based at least in part on the parameter related to the magnetic flux measured by the electromagnetic sensor and the distance measured by the depth sensor. In addition, the system includes a display system to display virtual content to a user based at least in part on the pose information of the electromagnetic sensor relative to the electromagnetic field emitter.
(FR) Un système d'affichage de réalité augmentée comprend un émetteur de champ électromagnétique pour émettre un champ magnétique connu dans un système de coordonnées connu. Le système comprend également un capteur électromagnétique pour mesurer un paramètre lié à un flux magnétique dans le capteur électromagnétique résultant du champ magnétique connu. Le système comprend en outre un capteur de profondeur pour mesurer une distance dans le système de coordonnées connu. Par ailleurs, le système comprend un contrôleur pour déterminer des informations de pose du capteur électromagnétique par rapport à l'émetteur de champ électromagnétique dans le système de coordonnées connu sur la base au moins en partie du paramètre lié au flux magnétique mesuré par le capteur électromagnétique et de la distance mesurée par le capteur de profondeur. En outre, le système comprend un système d'affichage pour afficher un contenu virtuel à un utilisateur sur la base au moins en partie des informations de pose du capteur électromagnétique par rapport à l'émetteur de champ électromagnétique.
