METHOD AND DEVICE FOR DETECTING WATER ON A VEHICLE WINDSCREEN

摘要

The invention relates to a method for detecting water on a vehicle windscreen (2). According to the invention, a plurality of individual images are captured through at least two regions of the vehicle windscreen (2) over a time period by means of an image capturing arrangement (3) disposed in a vehicle interior behind the vehicle windscreen (2), and corresponding pixels and/or corresponding image areas in simultaneously captured individual images are identified by performing a stereoscopic image evaluation of said simultaneously captured individual images. On the basis of a chronological evaluation of a similarity curve of the corresponding pixels and/or corresponding image areas in subsequently captured individual images, water striking the vehicle windscreen (2) is identified when the similarity of corresponding pixels and/or corresponding image areas is reduced over time. The invention further relates to a device for carrying out the method.
