The full handscanner is a 3-D scanner which captures the 3-D ridge detail of a full hand. The project was funded by NIHS over two grant periods and developed by a collaboration between University of Kentucky and FlashScan3D, LLC in San Antonio Texas. The method uses a sub-windowing technique, developed by FS3D, to capture the data, segments and post-processes 4 separate data streams using algorithms developed at UK. The subject slides their hand across the device where thousands of images slices are captured at high frame rate. Each slice contains Structured Light Illumination patterns which are processed to calculate the 3-Dimensional surface of the hand.
