Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. A method of analyzing a surface of an object, the method comprising:
performing a scan of the object with a 3D measurement device, the 3D measurement device being operable to measure 3D coordinates for a plurality of points on the surface;
generating a point cloud from the 3D coordinates of the plurality of points;
extracting a first set of points from the plurality of points;
defining a first reference geometry through the first set of points;
measuring at least one first metric from each of the points in the first set of points to the first reference geometry;
identifying a repetitive pattern on the first reference geometry;
identifying a nonconforming feature based at least in part on the at least one first metric and the repetitive pattern;
segmenting surfaces in the point cloud into a set of surfaces based on edges of the object;
defining an area of interest, the first set of points being disposed within the area of interest; and
moving the area of interest over each surface in the set of surfaces, wherein for each movement of the area of interest a second set of points is extracted from the plurality of points, a second reference geometry is fit through the second set of points, a second metric is measured from each of the points in the second set of points to the reference geometry, and a nonconforming feature is identified based at least in part on the second metric.
