Fusion of Time-of-Flight and Structured Light Scan

Fusion of Time-of-Flight and Structured Light Scan

Dr. Daniel L. Lau - Professor, University of Kentucky

This presentation will describe research performed at the University of Kentucky to use time-of-flight depth video to unwrap high-frequency phase data collected using a fringe projection structured light scanner. The resulting video provides 3D scans with the scan quality characteristic of structured light scanning at the high video rates of time-of-flight cameras.  The described system will be assembled from commodity hardware.  In addition to offering instructions on how to build the TOF+SLI system, this presentation will also review the calibration process used to align the fields of view of the two image sensors.  Finally, the described system will be demonstrated for applications in collaborative VR environments.
