Combinations of sensor types and enhanced processing methods may be employed for depth detection.
  • sensors collect point cloud data from the environment as the user moves the device and sensors through the environment. Sensor observations with varying points of view are combined to form a coherent 3D reconstruction of the complete environment.
  • the AR device proceeds to send the reconstructed model to the server along with a request for AR content.
  • the level of completeness may be measured for example as the percentage of the surrounding area coverage, number of discrete observations, duration of sensing, etc. and any similar quality value that may be used as a threshold.
  • 3D reconstruction of the environment may be carried out with any known reconstruction method, such as ones featured in KinectFusion or Point Cloud Library (PCL).
  • the AR device at the beginning of an AR viewing session starts to continuously stream RGB-D data to the server.
  • the server performs the 3D reconstruction process using the received RGB-D data stream and stores the reconstructed environment model.

User preferences may be used to look-up which racer is the user's favorite. The system may then provide the 3D model of that racer's car. If the primary media is footage of a security camera, then the AR content may be a 3D virtual model of the secure building.
  • An exemplary process described herein comprises analyzing the real-world environment to measure visual characteristics.
  • this includes hardware components such as sensors as well as software components such as object classifiers working together.

  • the analysis of the real-world environment may be carried out by the AR headset, an external sensor, an external computing device, and a combination thereof. For example, the analysis may not search for surfaces suitable for rendering virtual 3D content if the available AR content does not include any virtual 3D content types.
  • generating AR content render parameters comprises comparing each AR content in the selection with colors around the display to avoid render locations with poor contrast.
  • One example is not rendering a Christmas tree over a green wall.

  • One example is not rendering black text over a dark wall.
  • generating AR content render parameters comprises comparing each AR content in the selection with a visual complexity around the display to avoid visually complex render locations.

Abstract

La présente invention porte, dans un mode de réalisation, sur des systèmes et sur des procédés qui génèrent et affichent un contenu de réalité augmentée (AR) pour un environnement du monde réel dans lequel un affichage distinct est détecté par un visiocasque (HMD). Un contenu de réalité augmentée peut être sélectionné sur la base d'un contenu multimédia identifié sur l'affichage distinct. Un contenu de réalité augmentée peut être affiché à des emplacements, à proximité du dispositif d'affichage distinct, qui sont sélectionnés sur la base de caractéristiques visuelles des emplacements. Un contenu de réalité augmentée peut être affiché avec des paramètres de rendu qui augmentent la visibilité du contenu de réalité augmentée. Un mode de réalisation peut suivre la position et l'orientation du visiocasque et peut sélectionner un emplacement pour afficher le contenu de réalité augmentée sur la base de la position et de l'orientation du visiocasque. Un mode de réalisation peut afficher des connecteurs virtuels entre un contenu de réalité augmentée et des objets identifiés dans le contenu multimédia de l'affichage distinct. Un contenu de réalité augmentée peut être affiché à des emplacements qui réduisent à un minimum les intersections des connecteurs virtuels.
