Title
(DE) VERFAHREN ZUM EINSTELLEN EINER BLICKRICHTUNG IN EINER DARSTELLUNG EINER VIRTUELLEN UMGEBUNG
(EN) METHOD FOR SETTING A VIEWING DIRECTION IN A REPRESENTATION OF A VIRTUAL ENVIRONMENT
(FR) PROCÉDÉ DE RÉGLAGE D'UNE DIRECTION DE REGARD DANS UNE REPRÉSENTATION D'UN ENVIRONNEMENT VIRTUEL
Abstract
(DE) Vorgeschlagen wird ein Verfahren zum Einstellen einer Blickrichtung in einer Darstellung einer virtuellen Umgebung. Das Verfahren beinhaltet ein Aufnehmen eines bekannten Objektes in einer realen Umgebung mit einer Aufnahmevorrichtung. Weiterhin beinhaltet das Verfahren ein Bestimmen eines Rotationsversatzes der Blickrichtung in der Darstellung der virtuellen Umgebung um eine Gierachse der Darstellung der virtuellen Umgebung basierend auf der Aufnahme des Objekts, einer bekannten Position der Aufnahmevorrichtung in der realen Umgebung und einer momentanen Blickrichtung in der Darstellung der virtuellen Umgebung. Das Verfahren beinhaltet ferner ein Drehen der Blickrichtung in der Darstellung der virtuellen Umgebung um den Rotationsversatz.
(EN) Proposed is a method for setting a viewing direction in a representation of a virtual environment. The method includes recording a known object in a real environment with a recording device. The method further includes a determination of a rotational offset of the viewing direction in the representation of the virtual environment about a yaw axis of the representation of the virtual environment, based upon the recording of the object, a known position of the recording device in the real environment and a current viewing direction in the representation of the virtual environment. The method further includes a turning of the viewing direction in the representation of the virtual environment by the amount of the rotational offset.
(FR) L'invention concerne un procédé de réglage d'une direction de regard dans une représentation d'un environnement virtuel. Le procédé comprend une prise de vues d'un objet connu dans un environnement réel avec un dispositif de prise de vues. Le procédé comprend également une détermination d'un déplacement angulaire de la direction du regard, dans la représentation de l'environnement virtuel, autour d'un axe de lacet de la représentation de l'environnement virtuel sur la base de la prise de vues de l'objet, d'une position connue du dispositif de prise de vues dans l'environnement réel et d'une direction de regard momentanée dans la représentation de l'environnement virtuel. Le procédé comprend en outre une rotation de la direction du regard, dans la représentation de l'environnement virtuel, de la valeur du déplacement angulaire.
