Generalized Image Acquisition and Analysis
Three-Dimensional Kaleidoscopic Imaging
Three-dimensional kaleidoscopic imaging, a promising alternative for recording multi-view imagery. The main limitation of multi-view reconstruction techniques is the limited number of views that are available from multi-camera systems, especially for dynamic scenes. Our new system is based on imaging an object inside a kaleidoscopic mirror system. We show that this approach can generate a large number of high-quality views well distributed over the hemisphere surrounding the object in a single shot. In comparison to existing multi-view systems, our method offers a number of advantages: it is possible to operate with a single camera, the individual views are perfectly synchronized, and they have the same radiometric and colorimetric properties. We describe the setup both theoretically, and provide methods for a practical implementation. Enabling interfacing to standard multi-view algorithms for further processing is an important goal of our techniques.

Abstract
After decades of research on digital representations of
material and object appearance, computer graphics has more
recently turned to the problem of creating physical
artifacts with controllable appearance characteristics.
While this work has mostly progressed in two parallel
streams – display technologies as well as novel fabrication
processes – we believe there is a large overlap and the
potential for synergies between these two approaches. In
this report, we summarize research efforts from the worlds
of fabrication display, and categorize the different
approaches into a common taxonomy. We believe that this
report can serve as a basis for systematic exploration of
the design space in future research.
