Abstract

This paper proposes a high-accuracy image correction method using SIFT (Scale-Invariant Feature Transform) and POC (Phase-Only Correlation) for multi-projector display. The accurate correspondence between the projector and camera images is required to achieve seamless imagery in a multi-projector display. The conventional methods need to project and take special light patterns on a screen many times to obtain the correspondence. On the other hand, the proposed method needs to take only one snapshot of ordinary images so as to realize real-time geometric correction of projector images. Through a set of experiments, we demonstrate that the proposed method is effective for practical use of multi-projector display compared with the conventional methods.
