Abstract
In recent years, projectors are undergoing a transformation as they evolve from static output devices to portable, or communication systems. However, the projection images appear distorted unless the projector is precisely aligned to the projection screen. Generally many projection-based systems are corrected for oblique projection distortion using calibration methods (e.g., warping function). Computing a warping function uses fiducials or a special pattern projected to the screen. The methods can not use automatic calibration in real-time, like when projector is moving. We introduce a new technique for a real-time automatic calibration on planar surfaces using projected corner points. Our system provides a function of correcting image during the movement of the projector. An advantage of the proposed method is the system can be easily applied to ubiquitous computing.
