<p>Disclosed is a technique for displaying a shape of a road surface in front of a vehicle. The technique includes a beam emitter that emits one or more beams onto a predetermined layer toward a road surface in front of a vehicle. A beam receiver receives the one or more beams reflected from each layer after emitting the beams from the beam emitter, and a distance calculator calculates the distance to each layer respectively based on the amount of time that it takes for the one or more beams emitted from the beam emitter to be reflected. A shape determinator determines the shape of the road surface using a relationship between the distances of each layer and a display unit displays the shape of the road surface accordingly.</p> |
