SurfaceFX Feature Extract Technology
SurfaceFX (Surface Feature Extract) is a product that utilizes an algorithm which highlights surface features regardless of whether they are engraved, etched, embossed, dented, punctured, stamped, or raised. Once contrast is created in the image, Cognex's industry leading vision tools (OCRMax, PatMax RedLine, Blobs, InspectEdge, etc.) can easily inspect the part.
SurfaceFX utilizes a 4-segment quadrant controlled light and a Cognex IS8000 or IS5705 Series camera. It uses reflections and shadows from the different angled lights to determine the surface structure. The Cognex algorithm combines images from different light sources to create the resulting image.
