Abstract

By evaluating the volume data in the proximity of a surface point, a Local Quality Value (LQV) is calculated for each surface point of a Computed Tomography (CT) measurement. This allows an automatic and reliable identification of areas containing surface points with reduced accuracy. A colour-coded visualisation of the LQV allows a highlighted display of untrustworthy measurement data. This method is capable of identifying a broad range of artefacts (including beam hardening, noise and rounded off edges) and of points of reduced accuracy due to the fixture of the part on the rotational stage.
