Calibration Experiments of a Laser Scanner.

摘要

A LADAR is an instrument which 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 3-D models, positioning, derived quantities-depends largely on the accuracy and precision of the laser scanner. For global uncertainty analysis via error propagation, specific instrumental uncertainties need to be determined. This report chronicles exploratory experiments conducted at the National Institute of Standards and Technology to characterize a LADAR, focusing on accuracy and precision. The specific variables considered were distance, angle of incidence, and target color. Other characteristics of the LADAR such as the returned intensity and beam divergence were also examined.
