Surface error detection unit for metal casting inspection processes surface image to detect candidate pixel groups defining contours for comparison with reference contour
Surface error detection unit for metal casting inspection processes surface image to detect candidate pixel groups defining contours for comparison with reference contour
A surface error detection unit processes an image of the surface to detect pixels outside a set intensity deviation from a set threshold and group clusters of candidate pixels as blobs for examination to detect contrast edges for comparison with reference edges to determine possible errors. Independent claims are included for procedures used by the unit.
