Method and system for detecting edge defects on at least one workpiece

Abstract

A method for detecting edge defects on at least one workpiece includes providing imaging data of at least part of an edge of the at least one workpiece. An edge intensity image is generated based on the imaging data. A color difference image is generated based on the imaging data. The edge intensity image and the color difference image are segmented to generate a respective binary edge intensity image and a respective binary color difference image. The binary edge intensity image and the binary color difference image are combined and a combined binary mask is generated. A curve is fit to the at least part of an edge based on the combined binary mask, and the edge defects on the at least part of an edge of the at least one workpiece are detected based on the curve fitted to the at least part of an edge.
