Screen Object Tracking for Projector-based Mixed Reality

Abstract (in Japanese) (See Japanese page) 
(in English) In Projector-Based Mixed Reality, the method to deal with dynamic scenes is considered as an important factor to achieve interactive systems. We propose two methods for screen object tracking. One uses a visual marker attached to the bottom of screen object and a camera to capture it under the working space. This method has advantages of fast processing and precise registration. The other method uses an image-embedded pattern which is well recognizable by the camera but is rather invisible to human eyes. This pattern can be extracted from captured images and used to achieve three-dimensional tracking of screen object.
