Augmented reality l.jpg
Augmented Reality

  • Augmented Reality (AR) is a form of human-machine interaction where information is presented in the file of view of an individual

    • augmenting the real world scene necessitating that the user maintains a sense of presence in that world.

    • the virtual images are merged with the real view to create the augmented display.

    • technology for merging the real and virtual image streams in tight constrain.




Key technologies of ar l.jpg
Key Technologies of AR

  • accurate registration of the virtual objects with the real world image

    • camera position, viewing parameters

    • digital composition, scene lighting, object texture mapping

    • real-time processing constrain

    • user viewing method


Ar systems l.jpg
AR Systems

  • Monitor Based Augmented Reality

  • Video See-through Augmented Reality Display

  • Optical See-through Augmented Reality Display




Arcade augmented reality computing arena for digital entertainment l.jpg
ARCADE: Augmented Reality Computing Arena for Digital Entertainment

  • AR provides new ways of digital entertainment possibilities when combining with traditional entertainment channels.

  • Key applications: TV and Movie productions combining fantasy with reality

LYU0303: Video Object Tracking and Replacement for Post TV production

  • Design the special pattern markers for 3D objects to be applied on objects during the video shooting

  • Develop efficient algorithm to calculate the object’s positions and orientations in the video

    • Non real-time algorithm

    • MPEG-1 or DV quality video

    • The special pattern marks and the detection algorithm must survive from the partial occlusion of the object.

LYU0303: Video Object Tracking and Replacement for Post TV production

  • Develop algorithm to determine the lighting condition of the scene in a video

  • Generate realistic images to replace the video object according to it’s positions and orientations

    • non real-time algorithm

    • MPEG-1 or DV quality video

    • Simple object, soda can or cereal box

    • The algorithm must survive from the partial occlusion of the object

    • Photometric registration problem
