Method for detecting a mark made on a ground, driver assistance device and motor vehicle
First Claim
1. A method for using a driver assistance device of a motor vehicle to detect a marking made on a ground the method comprising:
- providing a two-dimensional image by an imaging sensor of the driver assistance device;
identifying a potential marking on the basis of the two-dimensional image;
performing a distance measurement by a distance sensor of the driver assistance device; and
taking a result of the distance measurement as a basis for determining whether the potential marking is the marking made on the ground or a marking on an object that is on the ground;
wherein when the result of the distance measurement does not detect an object, the potential marking is interpreted as the marking made on the ground.

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).

9. A driver assistance device for a motor vehicle, for detecting a marking made on a ground, having:
-
an imaging sensor for providing a two-dimensional image; an evaluation device for identifying a potential marking on the basis of the two-dimensional image; and a distance sensor for performing a distance measurement, wherein the evaluation device is designed to take a result of the distance measurement as a basis for determining whether the potential marking is the marking made on the ground or a marking on an object that is on the ground; wherein when the result of the distance measurement does not detect an object, the potential marking is interpreted as the marking made on the ground. - View Dependent Claims (10)
