METHOD AND APPARATUS FOR FINDING ANOMALIES IN FINISHED PARTS AND/OR ASSEMBLIES

摘要

A method for non-destructive examination of parts includes producing (114) a 3-D image (162) of a sample of a part, extracting (102) a point cloud of the image of the sample of the part, and registering (103) the point cloud to a CAD coordinate system. The method further includes determining (104) points (164) in the point cloud of the image that are more than a specified distance from surfaces on a CAD 3-D model of the part using the same coordinate system, and utilizing the determined points to determine the presence of anomalies or present (106) an image of anomalies in the sample of the part.
