Study on an augmented reality based 3-Dimensional see-through wall

This paper describes an augmented reality application system which can achieve 3-Dimensional perspective effect based on computer vision. In such a system a display screen is installed on a wall beside a window, its user can see the outside scene at any viewpoint with the help of the display screen. In addition, the scene displayed on the screen is matched with the scene through the neighbor window, as if the display screen is a real window. The system uses 3-Dimensional see-through rendering, marker tracking, image mosaic and vertex stretching methods to support single naked eye perspective directly. Experimental results show its potentials to be used in a wider application domain.
