1. A method for the detection and tracking of lane markings (12a, 12b, 12c) from a motor vehicle (10) on which an image capture device (14) is mounted, whereinan image (20, 20

  • ) of a space located in front of the vehicle (10), comprising a plurality of picture elements, is captured by the image capture device at regular intervals;

    the picture elements that meet a predetermined detection criterion are identified as detected lane markings in the captured image by an image processing system;

    at least one detected lane marking identified as a lane marking to be tracked is subjected to a tracking process in which the variation of the course of the lane marking in time in the plane of the roadway is tracked by means of a status estimator;

    at least one test zone (22) comprising a plurality of picture elements of the image is defined for each detected lane marking;

    with the aid of intensity values of the picture elements associated with the test zone, at least one parameter is determined; and

    the detected lane marking is assigned to one of a plurality of lane marking categories, depending on the parameter.
