Acquisition Rig: Dome
We decided to use a multiple-light multiple-camera dome to acquire the
data (at each time step, it is SV-BRDF (Spatially-Varying BRDF)).
The dome was originally built in MERL,
mainly by Tim
Weyrich and other
researchers. It has been used in several other projects for face
scanning and other acquisitions.
The plan of the dome is
shown in the following image. The circled camera (7) and the
lights (53, 54, 80, 83, 106, 107) are the 6 measurements we released in
this database. The specification of the dome and the coordinates of the
cameras and light sources can be found here
(1.2MB). Note that we have calibrated the dome at different time periods,
so it contains multiple sets of camera data.
