Panoramic 3D a step closer

A 3D prototype of an existing prototype panoramic video camera has been developed at renowned German research lab Fraunhofer HHI. The device features a circular rig capable of carrying up to 30 HD cameras and 15 mirrors to form a continuous 360-degree panorama. …
According to Fraunhofer HHI the rig is scalable in increments of 24 degrees and supports acquisition of live 3D video panoramas of up to 360 degrees with a maximal resolution of about 15.000× 2.000 pixels for each stereo view. …
Generating 3D video panoramas, however, is much more complicated. Whereas the stitching of each panorama for the left and the right eye requires a parallax-free recording of sub-images, the stereo representation itself needs a sufficient amount of parallax for proper 3D reproduction. …
The depth budget for 3D stereo reproduction is controlled independently by adjusting the baseline in the given range.
As proof of concept, Fraunhofer HHI has built a first prototype of the 3D Omnicam with three mirror segments and six HD cameras.
