Abstract

This paper proposes a geometric correction method using stereo camera for projected images. When we use a projector in the various places, a projected image is deformed due to the shape of a display surface, the positional relationship between a projector and a display surface, etc. Addressing this problem, we propose a geometric correction method for projected images, which employs 3D measurement technique with the stereo camera. The proposed method enables us to automatically correct the deformation of projected images during the projection of ordinary images. In our method, we employ the correspondence search technique based on Phase-Only Correlation (POC) to obtain dense 3D shape of the display surface. A set of experiments demonstrates that the proposed method is effective for correcting deformation of projected images.
