Abstract

In recent years, projection device which has advanced its miniaturization and price reduction are attracted as display device against a backdrop of high needs for wide and high-definition screen. However, the expression of projector on non-special screen causes geometric problems of distorted expression caused by a surface shape of the screen and a positional relation among devices. To solve these problems, a lot of methods have been our proposing by regarding a camera device as a viewer, transforming input projector images based on acquired images by a camera device. In this paper, we propose fast geometric correction method with easy calculation by using only Gray code pattern, and show that new method is robust for design patterns of screen by evaluation experiment.
