Abstract
The invention relates to a method for using a driver assistance device of a motor vehicle (1) to detect a mark (7) made on a ground (6) by providing a two-dimensional image by means of an imaging sensor (3) of the driver assistance device (2); by identifying a potential mark (7″) on the basis of the two-dimensional image (11); and by performing a distance measurement by means of a distance sensor (4) of the driver assistance device and also taking a result (17) of the distance measurement as a basis for determining whether the potential mark (7″) is the mark (7) made on the ground (6) or a mark (14) on an object (13) that is on the ground (6).
