Abstract
A method for recognizing directional structures on a window pane of a vehicle is described. The method includes carrying out an assessment of image points of an image of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane. The method further includes recognizing a directional structure based on the assessment.

14. A method for recognizing directional structures on a window pane of a vehicle, comprising:
-
carrying out an assessment of image points of an image of at least a portion of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane; and recognizing a directional structure based on the assessment. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for recognizing directional structures on a window pane of a vehicle, comprising:
-
carrying out an assessment of image points of an image of the window pane, which image points are disposed along an evaluation path, a course of the evaluation path being dependent on an expected orientation of the directional structures on the window pane; carrying out a determination of whether an image point disposed along the evaluation path constitutes a light diffraction effect in a region of the window pane represented by the image point; and recognizing a directional structure based on the assessment and the determination.
