Method and device for determining a valid lane marking
First Claim
1. A method for determining a lane with the aid of a camera system of a vehicle, in which:
- with the aid of a camera of the camera system, several pictures comprising images of an area in front of the vehicle are successively taken as a picture series, and image data corresponding to the respective pictures are generated;
objects and/or object images are detected by processing the image data of at least a part of at least one of the pictures of the picture series, wherein the detected objects and/or objects include a warning barrier, a traffic sign, a guard rail, a guiding reflector post, a street light, a vehicle driving ahead and/or an oncoming vehicle; and
the lane is determined dependent, at least in part, on a position of at least one detected object and/or object image relative to the lane.

Abstract
The invention relates to a method and a device for determining a valid lane marking (38 to 42; 56, 58) with the aid of a camera system (16) of a vehicle (12), in particular a road vehicle. With the aid of a camera (17) of the camera system (16) several pictures with an image of an area in front of the vehicle (12) are taken successively as a picture series and image data corresponding to the respective picture (30, 54, 66) are generated. The image data of at least a part of the pictures (30, 54, 66) of the picture series are processed, at least a first lane marking (38 to 42) and a second lane marking (56, 58) different from the first lane marking (38 to 42) being detected in at least one picture (30) of the picture series. A vehicle (34) driving ahead of the vehicle (12) is detected in at least two successively taken pictures (30, 54) and its position (P1 to P4) relative to the first lane marking (36 to 42) as well as its position (P1 to P4) relative to the second lane marking (56, 58) is determined. Dependent on the positions (P1 to P4) of the vehicle driving ahead (34) determined with the aid of the pictures (30, 54), one of the detected lane markings (36 to 42, 56, 58) is selected as the valid lane marking (56, 58).
