1. A method of determining the configuration of a path for motor vehicles on roadways in which extraneous clutter and noise is relatively minimal, comprising the steps of:

  • extracting straight lines from a group of straight lines which have been redetermined from original image data of the path based on an array of feature points included in said original image data, wherein the extracted straight lines determine boundaries of the path;

    dividing the extracted straight lines into a plurality of line segments, each of said line segments being defined by points of intersection between the straight lines; and

    comparing said line segments with the feature points of said original image data to determine whether the line segments correspond to the boundaries of the path.
