Acquisition Process
Multi-view sequences were acquired with a rig of synchronized, progressive-scan Pulnix TMC9700 color cameras. Each camera was connected via RGBSync cables to a dedicated PC containing one multi-channel Matrox Meteor II framegrabber. Frames were grabbed uncompressed at a rate of 30 frames/second into the PC's internal memory.
The cameras allowed simultaneous observation of an approximately 30x30x30cm working volume, as shown below. Only seven of the rig's twelve cameras were used for acquiring the sequences.
All cameras were calibrated geometrically and radiometrically prior to image acquisition. Calibration was performed using the Vista implementation of Tsai's calibration algorithm. Reprojection accuracy within the working volume was approximately 0.5 pixels for the datasets below.
Scene illumination consisted of two 800W halogen point light sources whose 3D positions were recovered by adapting the method described by Bouguet.
Camera calibration and light source positions were unchanged for all sequences captured.
All sequences were acquired at the University of Rochester by Rodrigo Carceroni.
