Abstract: A processor-implemented method with lane line determination includes: determining, from an input image, road feature information comprising a surrounding object and a road surface marking comprising a lane line; matching the road feature information to lane lines of a driving road on which a vehicle is driving; detecting whether there is a change in a road structure based on a result of the matching, wherein the change in the road structure comprises any one or any combination of any two or more of a change of the lane line, a loss of the lane line, and a change of a road sign; and based on whether the change in the road structure is detected, determining lane line information of the driving road by using information on the surrounding object.

Abstract: A method and apparatus for calibrating a camera are provided. The method and apparatus include obtaining a driving image captured by a camera mounted on a vehicle, segmenting line regions including straight lines from the captured driving image, extracting feature points of the straight lines from the line regions, projecting the feature points of the straight lines into a world coordinate system, and estimating an error for a calibration parameter of the camera including at least one of a pitch, a roll, or a yaw so that the feature points projected into the world coordinate system satisfy a line parallel condition.
