Task-specific systematic error evaluation of optical 3D coordinate measuring systems
Abstract
Optical 3D Coordinate Measuring Systems (CMSs) are an effective alternative to tactile CMMs for measuring complex geometries. Uncertainty evaluation is a critical task for verifying compliance with specifications, but methods for such CMSs are missing. This work investigates the effect of workpiece geometrical characteristics on the systematic error. Results show a dependence on the workpiece characteristics that required task-specific uncertainty evaluations, and an apparent form error induced by interactions between the view direction and the workpiece geometry. Results enable artefacts’ design to improve the verification representativeness, and to model and validate requirements for digital twins to compensate for measurement errors.
