Abstract:

Three-dimensional (3D) optical scanning technology has made great advances over the last decade and the range of applications is continually growing. However, performance of scanning systems and the quality of measurement data can vary greatly with application. This paper discusses the need for customised reference artefacts and describes three calibrated freeform artefacts, developed at the National Physical Laboratory (NPL) - one related to generic freeform shapes, one related to body scanning, and another relating to dental scanning. The design, manufacture, calibration and implementation of these artefacts are discussed, together with examples of how they are used to add value to a measurement process.
