Description
Although 3D scanning has become a widely-used technique, most commercially
available systems acquire data at relatively low rates and require careful
control over the setup and calibration of cameras and/or active light sources.
We are working on making range scanning systems faster, more flexible, more
robust, and easier to use by developing novel scanner designs and 3D scan
processing algorithms, including combinations of structured light,
spacetime stereo, photometric stereo, and efficient registration algorithms.
