Abstract
(EN)
An augmented reality system for providing depth perspective includes a sensor system that provides spatial data of objects in a surrounding environment of a user. A computer processor system calculates spatial information of the objects from the spatial data received the sensor system. The computer processor system determines a depth-to-color mapping in which distance of objects from the user is mapped to a predetermined viewable representation. The system also includes a head mountable display that displays the depth-to-color mapping to the user. Characteristically, distances of the objects from the user are rendered to allow at least partial viewability of the object by the user. A method utilizing the augmented reality system is also provided.

L'invention concerne un système de réalité augmentée destiné à fournir une perspective de profondeur qui comprend un système de capteur qui fournit des données spatiales d'objets dans un environnement environnant d'un utilisateur. Un système de processeur informatique calcule des informations spatiales des objets à partir des données spatiales reçues du système de capteurs. Le système de processeur informatique détermine un mappage profondeur-couleur dans lequel la distance d'objets de l'utilisateur est mappée à une représentation visualisable prédéterminée. Le système comprend également un visiocasque qui affiche le mappage profondeur-couleur pour l'utilisateur. De manière caractéristique, les distances des objets de l'utilisateur sont rendues pour permettre au moins une visibilité partielle de l'objet par l'utilisateur. L'invention se rapporte également à un procédé utilisant le système de réalité augmentée.
