The National Research Council of Canada (NRC) is currently evaluating and designing artifacts and methods to
completely characterize 3-D imaging systems. We have gathered a set of artifacts to form a low-cost portable case and
provide a clearly-defined set of procedures for generating characteristic values using these artifacts. In its current
version, this case is specifically designed for the characterization of short-range (standoff distance of 1 centimeter to 3
meters) triangulation-based 3-D imaging systems. The case is known as the "NRC Portable Target Case for Short-Range
Triangulation-based 3-D Imaging Systems" (NRC-PTC). The artifacts in the case have been carefully chosen for their
geometric, thermal, and optical properties. A set of characterization procedures are provided with these artifacts based on
procedures either already in use or are based on knowledge acquired from various tests carried out by the NRC.
Geometric dimensioning and tolerancing (GD&T), a well-known terminology in the industrial field, was used to define
the set of tests. The following parameters of a system are characterized: dimensional properties, form properties,
orientation properties, localization properties, profile properties, repeatability, intermediate precision, and
reproducibility. A number of tests were performed in a special dimensional metrology laboratory to validate the
capability of the NRC-PTC. The NRC-PTC will soon be subjected to reproducibility testing using an intercomparison
evaluation to validate its use in different laboratories.
