In Projector-Based Mixed Reality, a method to deal with dynamic scenes is considered as an important factor to achieve interactive systems. We have developed a simple system which consists only of a camera and a projector to track the screen object and to project images onto the object. We propose a method for tracking the screen object based on the pattern embedding technique. This embedded pattern can be well recognized by the camera, despite it is invisible to human eyes. The embedded pattern is extracted from captured images and used for 3-D tracking of the object. Our method utilizes the difference of color sensitivity between camera and human eyes. To find optimal embedding color, we derive transformation functions of color space among projected color, observed color by the camera, and psychophysical color without troublesome calibration. Some experimental results show that the adaptive image projection onto dynamic scenes can be realized. |
