METHOD OF PROCESSING IMAGE FOR RECOGNIZING A LANE AND THE SYSTEM THEREOF

摘要

A method and a system for processing an image for lane recognition are provided to check lane extraction, curvature estimation, and positional relations between lanes and vehicles even in various road environments, thereby previously estimating the lane departure time and reducing the wrong alarm. An image is received during driving, and lane candidates are extracted(220). A histogram for the extracted lane candidates is generated to determine a position of a short-distance lane(240). Curvatures of long-distance lane candidates are calculated based on a curvature of the short-distance lane(250). A lane is recognized by comparing the curvature of the short-distance lane with the curvatures of the long-distance lane candidates(260).
