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.

In the press

Our work on dynamically displaying BRDFs is going to be featured in the September issue of 3D World, a magazine for 3D artists, covering SIGGRAPH's Emerging Technologies where we will demo our work. Matthias Hullin is quoted as "I don't expect a BRDF display to become available in the next 20 years. The principle on which the Nintendo 3DS is based was patented back in 1913!" -->
