Abstract: Disclosed is a lane departure warning system. The lane departure warning system includes an image photographing unit attached to a front of a vehicle to photograph an object in a forward direction of the vehicle; a driving unit receiving image data from the image photographing unit, filtering the image data to search for a lane pair, converting an image coordinate of the image data into a real coordinate to calculate a lateral distance between the lane pair and the vehicle and to calculate a lateral speed of the vehicle, and generating a warning generating signal as a time of lane change elapses by obtaining the time of lane change; and a warning unit receiving the warning generating signal to generate a lane departure warning signal. The time of lane change can be acquired by calculating the lateral distance between the vehicle and the lane after converting the image coordinate into the real coordinate, so that the failure can be reduced, thereby improving reliability.
