Zusammenfassung:	A multi-camera skin inspection system for inspecting the outer skin and the skin perimeter of extruded ceramic honeycomb structures is disclosed. The system has a camera that captures first digital line images of a line-illuminated portion of the outer skin as the ceramic honeycomb structure rotates to form a scanned digital image of the outer skin. The system also has second and third cameras that respectively capture second and third digital line images of illuminated first and second endfaces, including the corresponding first and second skin perimeters, as the ceramic honeycomb structure rotates to form scanned digital images of the ceramic honeycomb structure perimeters. The system also forms a composite image from the three scanned images and identifies at least one defect in the ceramic honeycomb structure from the composite image.
