AN ON-LINE INSPECTION SYSTEM

摘要

A method for training an inspection system comprising: capturing images of a material, for example a web or sheet of material, using one or more cameras (46); auto-training one or more of a plurality of image processing techniques using the captured images (48); using the trained image processing techniques to identify faults; visually inspecting the material to identify faults (56); identifying any discrepancies in the faults detected by the visual inspection and the image processing, and when necessary varying one or more parameters associated with the one or more processes to improve its fault detecting capability (58, 60). The method may further involve recording visual images (52) of each web and using the recorded images in the visual inspection. Optionally, similar materials may be grouped together (50).
