Abstract

Es wird ein Verfahren zur Bestimmung eines Strukturbildes einer Scheibe (102) vorgeschlagen, wobei das Strukturbild zur Detektion einer Sichtbeeinträchtigung (203) der Scheibe, insbesondere von Regentropfen, geeignet ist. Das Verfahren umfasst einen Schritt des Entfernens einer Hintergrundhelligkeit (214) aus einem Bild (210) der Scheibe, auf dem eine Oberfläche der Scheibe scharf und ein Hintergrund der Scheibe unscharf dargestellt ist, um ein Strukturbild (212) der Scheibe zu bestimmen. In einem weiteren Schritt erfolgt ein Hervorheben von in dem Strukturbild vorhandenen Bildstrukturen, um ein verstärktes Strukturbild (316) der Scheibe zu bestimmen.
