Abstract:
1. A system for the detection and tracking of lane markings proximate to a motor vehicle, said system comprising: an image capture device mounted on the motor vehicle and configured to capture an image of a space located in front of the vehicle, wherein the image includes a plurality of picture elements, the image 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 image, 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, at least one test zone 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, wherein from the intensity values of the picture elements associated with the test zone statistical parameters are determined that include an average intensity value, an intensity value total, a maximum intensity value, a minimum intensity value, and a moment of intensity value distribution of the picture elements.
