Abstract
A method of detecting a road lane in an electronically stored image. An image acquisition device acquires an image of a road lane environment and stores the image as an array of pixels. An edge detector generates a list of feature edges form the image. Lane marker edge pairs are filtered from the list of features according to a set of criteria. Lane marker edge pairs are sorted into lists corresponding to individual lane markers. Individual lane markers defining a left and right boundary of a road lane are geometrically identified. Three dimensional curves are fit along centers of mass of the sets of left and right lane markers to model a road lane boundary.
