    Concave surround optics for rapid multiview imaging

Abstract:


    Many image-based computer graphics techniques involve photographing a subject from many different viewpoints. This is usually accomplished by moving the camera, moving the subject, or using an array of cameras. In this work, we use a system of mirrors to create the appearance of camera movement around the subject while both the camera and subject are fixed. Our first use of the system produces slow-motion video of a dynamic subject with smooth rotational camera motion during the event.  While high-speed photography has long been used for the analysis of complex motions such as turbulent liquids, speeding bullets,  and human movement, such video is typically restricted to a static viewpoint, limiting the sense of three-dimensional structure.
