Abstract: A method for filtering a measurement data set usable for specifying and/or verifying an internal feature of a workpiece, the method includes providing a measurement data set comprising a plurality of measurement points of the internal feature; providing an auxiliary feature representing an ideal estimate for the internal feature of the workpiece; mirroring each measurement point of the measurement data set on a boundary element of the auxiliary feature, thereby generating a first modified data set comprising a plurality of first modified measurement points; determining a convex hull of the first modified measurement points and projecting the first modified measurement points onto the determined convex hull, thereby generating a second modified data set comprising a plurality of second modified measurement points; and mirroring each second modified measurement point on the boundary element of the auxiliary feature, thereby generating a filtered measurement data set comprising a plurality of filtered measuremen

Abstract: A computer-implemented method for determining a two-point size of a workpiece includes receiving a set of measuring points of the workpiece, determining a longitudinal axis of the workpiece based on the set of measuring points, projecting at least a part of the set of measuring points into a projection plane perpendicular to the longitudinal axis to obtain a set of projection points, and determining a two-point size of the workpiece based on the projection point.
