| Abstract(in English) | In this paper, we present an experimental study of geometric correction for projected images using projector-camera systems. When we use a projector in the various places in the real world, a projected image is distorted 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 narrow-baseline stereo camera. In the proposed method, we use the correspondence search technique based on Phase-Only Correlation (POC) to obtain the 3D shape of the display surface. Experimental results show the proposed technique is effective for correcting distortion of projected images. |
