A review of 20 years of range sensor development

This paper quickly reviews 20 years of development in the field of 3D laser imaging. An overview of 3D digitizing techniques is presented with an emphasis on some of the numerous commercial techniques and systems currently available. This paper covers some of the most important methods that have been developed during the years, both at NRC and elsewhere, with a focus on commercial systems, which are good representations of the key technologies that survived the test of the years.
