Abstract
This paper summarizes the causes of uncertainty in 3D data measurement, some basic theory of 3D imaging that explains the origin of some of these causes, and, describes the properties and performances of a 100 square meter facility to perform research in traceable 3D imaging metrology. Built in 2006, the laboratory space allows accurate measurements of 3D data from devices operating at standoff distances from a few centimeters up to 10 meters. A laminar flow of 20°C air at 50% humidity level is maintained within ±0.1°C. The total volume of air in the lab is changed twice a minute (18 000 cfm). This characteristic combined with the air filtering design allows air cleanliness to be exceptionally good (Class 100).
