Title:  Range data: Image acquistion and Surface reconstruction
Abstract:
One of the major research topics of Dr. WonSook Lee’s group at the University of Ottawa is 3D face modeling and animation. Currently,  we use the 3D face models got from a Cyberware head and face scanner at Discover lab for our facial modeling and animation work.
Range imaging offers an inexpensive and accurate means for digitizing the shape of three-dimensional objects. With the growing of number of 3D range scanning productions, you may find yourself asking “how do these technologies work?” and “how can I make use of the shape data they produce?”. In this talk, we will introduce several common range scanning technologies, step through a pipeline that takes the range data into a single geometric model. There are many techniques having been developed for the problem of surface reconstruction from range images. Among them, volumetric method is a robust one to noise and will also be discussed.
