A review of laser scanning three-dimensional digitisers

A big number of products are sold by their shape features, hence, process engineers are including more and more accurate 3D digitisers in their manufacturing assembly lines. Acquisition and data processing speed are becoming important issues to consider when choosing the right device to be incorporated in the inspection equipment without loss of accuracy. This paper is intended to present an exhaustive review of the state-of-the-art about laser scanning three-dimensional digitisers, proposing a classification of such systems.
