提出了一种基于SIFT（Scale-Invariant Feature Transform）和POC（Phase-Only Correlation）的多投影显示图像校正方法。投影仪和摄像机图像之间的准确对应关系是实现多投影仪显示中的无缝图像所必需的。传统的方法需要在屏幕上多次投射和拍摄特殊的光图案来获得对应关系。另一方面，该方法只需对普通图像进行一次快照，即可实现投影图像的实时几何校正。通过一组实验，我们证明了所提出的方法是有效的多投影仪显示的实际使用相比，传统的方法。
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 multiprojector 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.
