Calibration Experiments Of A Laser Scanner

The potential applications of laser scanners or LADARs (Laser Detection & Ranging) cross several sectors of the industry -- construction, large-scale mfg., remote sensing, nat. defense. A LADAR can rapidly capture 3-D data of a scene in the form of x, y, z points. The confidence in end products of the applications -- 3D models, positioning, derived quantities -- depends largely on the accuracy & precision of the laser scanner. This report chronicles experiments to characterize a LADAR, focusing on accuracy & precision. The variables considered were distance, angle of incidence, & target color. Other characteristics such as the returned intensity & beam divergence were also examined. Findings indicate no obvious global color effect on accuracy.Cheok, Geraldine S. is the author of 'Calibration Experiments Of A Laser Scanner', published 2004 under ISBN 9780756742614 and ISBN 0756742617.
