Understanding the GUM Methodology: Applications to Point Clouds in Coordinate Metrology

In the field of coordinate metrology, where precision is paramount, the accurate assessment of measurement uncertainty is essential for ensuring reliable results. The Guide to the Expression of Uncertainty in Measurement (GUM) provides a standardized framework for evaluating and expressing this uncertainty. Developed collaboratively by international metrology organizations, GUM has become the cornerstone for uncertainty analysis across various measurement disciplines, including those involving coordinate measuring machines (CMMs) and 3D scanning technologies.
