Abstract
Disclosed herein is a method of recognizing the location of a current lane in which a vehicle is traveling, using a radar and an imaging device. The method includes: detecting the locations of the fixed objects using an object detector; capturing a photograph of the road surface ahead using an imaging device; calculating, by a controller, the entire width of a traveling road based on the locations of the fixed objects at the left side and the right side; calculating, by the controller the width of a traveling lane from the photograph of the road surface; and calculating, by the controller, the lane in which the vehicle is traveling based on the calculated width of the traveling lane and the entire width of the traveling road.
