All-Around Convergent view Acquisition System using Ellipsoidal Mirrors

摘要

In this paper, we present a new image acquisition system for FTV (Free-viewpoint TV). The proposed system can capture the dynamic scene from all-around views. The proposed system consists of two ellipsoidal mirrors, a high-speed camera, and a rotating aslope mirror. As for two ellipsoidal mirrors, the size and the ellipticity are mutually different. The object is set in the focus of ellipsoidal mirror. The size of this system is smaller than that of early system since ellipsoidal mirrors can reduce virtual images. High-speed camera can acquire multi viewpoint images by mirror scanning. Here, we simulated this system with ray tracing and confirmed the principle.
