Abstract

Die Erfindung betrifft ein Verfahren zur automatisierten optischen Erkennung von Einschlüssen (1) in einer Oberfläche (2), insbesondere einer Oberfläche (2) eines metallischen Gegenstandes, wobei die Einschlüsse (1) klassifiziert werden. Erfindungsgemäß ist vorgesehen, dass das Verfahren folgende Schritte umfasst: a) Erzeugung eines Bildes (3) der Oberfläche (2); b) optional Aufbereitung des Bildes (3), um Artefakte zu minimieren;c) Bestimmung von einem oder mehreren zusammenhängenden Gebieten (4), wobei die zusammenhängenden Gebiete (4) insbesondere mittels morphologischer und/oder struktureller Algorithmen bestimmt werden;d) Merkmalsextraktion für die erfassten zusammenhängenden Gebiete (4) und Berechnung von Kenngrößen aus diesen; e) Vergleich extrahierter Kenngrößen mit Referenzgrößen für verschiedene Einschlusstypen und Klassifikation der Einschlüsse (1). Durch ein erfindungsgemäßes Verfahren wird eine objektive Beurteilung der Einschlüsse (1) nach Richtlinien bzw. Standards, eine schnelle und korrekte Klassifikation und darüberhinaus eine Schonung bzw. ein Schutz einer menschlichen Arbeitskraft erreicht.The invention relates to a method for the automated optical detection of inclusions (1) in a surface (2), in particular a surface (2) of a metallic object, wherein the inclusions (1) are classified. According to the invention, the method comprises the following steps: a) generating an image (3) of the surface (2); b) optionally rendering the image (3) to minimize artifacts c) determining one or more contiguous regions (4), the contiguous regions (4) being determined, in particular, by morphological and / or structural algorithms d) feature extraction for the recorded contiguous areas (4) and the calculation of characteristics therefrom; e) Comparison of extracted parameters with reference variables for different inclusion types and classification of inclusions (1). By means of a method according to the invention, an objective assessment of the inclusions (1) according to guidelines or standards, a quick and correct classification and, moreover, a protection or protection of a human worker is achieved.
