of 3-D Video and Human-Computer Interfacing
Historical note from 1997:
A primary branch of our research is in 3-D data acquisition. Most of our effort has been in the study of structured light techniques involving light striping while some of our earlier work involved acoustic imaging. Our latest work is in real time 3-D data acquisition and processing using high speed Spatial Light Modulation (SLM) devices. In these systems, we use time and space light stripe modulation techniques to achieve high SNR as well as high through put. We believe that this area of study is becoming very important for both industrial and commercial applications. In the past decades many methodologies of structured light have been developed. However, these methods have been limited by the computational requirements. With the emergence of low cost high speed general purpose computers and standardized high speed buses and interfaces, many of these methods become practical. In the last few years SLM technology has reached speeds that will support data acquisition rates, and preprocessing capabilities that will allow for 3-D data acquisition/reconstruction near video rates. We have already begun preliminary work in this area and in the next two years our group will be publishing on this latter topic and our efforts will be documented in these web pages. We list existing research below and invite you to look over discussion and graphical examples linked below. A theme of this discussion link is that a $1K scanner is practical with todays technology.
