38. Fast automatic registration of range images from 3D imaging systems using sphere targets
Published: 1/1/2008
Authors: Marek Franaszek, Geraldine S Cheok, Christoph Johann Witzgall
Abstract: 3D imaging systems are line of sight instruments and multiple scans from different locations are often needed to get a good representation of an entire scene. Therefore, registration of different datasets to a common coordinate system is required. A ...
