A lane departure warning system and method are provided. The lane departure warning system includes a camera, a tunnel recognition module, a virtual lane module, and a determination/warning module. The camera captures a front image of a vehicle. The tunnel recognition module determines whether a current position of the vehicle is in a tunnel section, using the front image captured by the camera. The virtual lane module determines whether two or more lanes are detected from the front image when the current position is in the tunnel section and, when only one lane is detected, generates a virtual lane at a position corresponding to the one lane using a pre-calculated road width. The determination/warning module determines whether the vehicle departs from a lane, using the one lane and the virtual lane or the two or more lanes detected, and warns of lane departures accordingly. |
