A calibration sphere may have excellent dimensional accuracy, but that does not always mean a measurement system will obtain the

Structured light 3D scanners use cameras and projected light to capture the geometry of an object. The quality of the

In precision 3D measurement, the calibration artifact is part of the measurement system. It provides a known geometric reference that

Quick Answer Choosing the correct reference sphere size is not simply about selecting the largest or most accurate sphere available.

Quick Answer There is no single surface finish that is best for every metrology application. Polished ceramic spheres are often

Quick Answer Ceramic reference spheres are precision spherical standards used to establish or verify geometric references in coordinate measurement, optical

Quick Answer For optical 3D scanner calibration, both ceramic and metal reference spheres can provide accurate geometric references. The difference
