PROCEDE ET DISPOSIIF OPTIQUES DE DETECTION DE DEFAUTS DE SURFACE ET DE STRUCTURE D'UN PRODUIT CHAUD EN DEFILEMENT

The method involves providing a signal of detection of defects by a set of linear sensors (C1, C2, C3) that are associated with the detection of an image. The sensors are set up with a camera (4), where each of the sensors have respective axes parallel to a line of sight substantially perpendicular...

Zusammenfassung:	The method involves providing a signal of detection of defects by a set of linear sensors (C1, C2, C3) that are associated with the detection of an image. The sensors are set up with a camera (4), where each of the sensors have respective axes parallel to a line of sight substantially perpendicular to the direction of travel of a hot traveling product. The sensors are located in a different focal planes (P r, P g, P b) associated with a wavelength range in order to obtain superposable images. The defect detection signal is transmitted to an image processing computer for processing images. An independent claim is also included for an optical device for detecting the defects of a hot traveling product.
