1. A method for automatically determining a wear condition of a vehicle component by 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;
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;
recognizing a directional structure based on the assessment and the determination;
based at least on the determining, classifying a wear condition of the vehicle component; and
based at least on the classifying, alerting a user of the wear condition.

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. An apparatus for automatically determining a wear condition of a vehicle component by recognizing directional structures on a window pane of a vehicle, comprising:
-
an image capture device to capture an image of the window pane; an implementation device which receives the image of the window pane from the image capture device and carries out an assessment of image points of the 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, and carry 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; a recognition device recognize a directional structure based on the assessment and determine the wear condition of the vehicle component based on the assessment; and an alert device to alert a user of the wear condition.

15. A non-transitory computer readable medium storing program code to automatically determine a wear condition of a vehicle component by recognizing directional structures on a window pane of a vehicle, the program code, when executed by an information system, causing the information system to perform the following steps:
-
receiving an image of at least a portion of the window pane from an image capture device; carrying out an assessment of image points of the received 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; 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; recognizing a directional structure based on assessment; based at least on the assessment, determining the wear condition of the vehicle component; and based at least on the determining, alerting a user of the wear condition.
