(EN) MIXED REALITY VISUALISATION SYSTEM
(FR) SYSTÈME DE VISUALISATION DE RÉALITÉ MIXTE
Abstract
(EN)
A method for accurately anchoring a floorplan and/or 3D model to a live video view of a site on which the floorplan has been depicted on a site map; the method comprising producing an isolated site view; and wherein the isolated site view is produced by removing the floorplan from the site map by looking for floorplan artefacts such as the door and window geometry and then expanding to include geometry with straight lines forming concave shapes. Also disclosed is a mixed reality headset having a display which combines reality vision of site of a pre-determined environment with a three-dimensional representation of a three-dimensional structure; the representation of the three-dimensional structure referenced against an artefact in the pre-determined environment.
(FR)
L'invention concerne un procédé d'ancrage précis d'un plan de masse et/ou d'un modèle 3D à une vue vidéo en direct d'un site sur lequel le plan de masse a été représenté sur une carte de site ; le procédé comprenant la production d'une vue de site isolée ; et la vue de site isolée étant produite en retirant le plan de masse de la carte de site en recherchant des artefacts de plan de masse tels que la géométrie de porte et de fenêtre, puis en se dilatant pour inclure une géométrie avec des lignes droites formant des formes concaves. L'invention concerne également un casque de réalité mixte ayant un écran qui combine la vision de réalité du site d'un environnement prédéterminé avec une représentation tridimensionnelle d'une structure tridimensionnelle ; la représentation de la structure tridimensionnelle référencée contre un artefact dans l'environnement prédéterminé.
