METHOD AND DEVICE FOR DETECTING IMPAIRMENT OF VISIBILITY THROUGH A PANE

摘要

The invention relates to a method for determining a structural image of a pane (102), the structural image being suitable for the detection of impairment of visibility (203) through the pane, in particular by raindrops. The method comprises a step of removing the background brightness (214) from an image (210) of the pane, on which the surface of the pane is displayed sharply and the background of the pane is displayed non-sharply, in order to determine a structural image (212) of the pane. In a further step, image structures present in the structural image are emphasized in order to determine an intensified structural image (316) of the pane.
