Simple and accurate geometric correction with multiple projectors

DOI

Description

In this study, we demonstrate that it is possible to provide accurate multi-projection over a whole space using a simple procedure and commercially available cameras by arranging multiple projectors freely. Increasing research interest in projection mapping is providing growing opportunities for application of this technique, resulting in a mounting need for simple and highly accurate image projection techniques for entire spaces. Effective projection is difficult to achieve using only one projector, but the use of multiple projectors requires highly complex projection techniques. In this study, we propose a novel and effective geometric correction technique that combines the use of a fish-eye lens camera and a standard lens camera.
