A parallel guaranteed projector-camera system for dual videography

Abstract

Thanks to the optical duality between a projector and a camera, an image from the viewpoint of the projector can be computationally generated using camera images;however, to achieve dual photography in real time, the geometric configuration of the projector and the camera must be strongly constrained. In this research, to substantially relax this constraint, we improved the optical components of the projector–camera system by employing a stabilizer to guarantee that both epipolar planes are parallel. As a result, it is possible to move the projector to change the synthesized virtual viewpoint more freely in real–time.
