A lane departure warning system which uses at least one detection device, such as a stereo camera, to map the surrounding environment in three-dimensions, which provides for a determination of the distance of various objects in a given image obtained by the camera. With the information obtained by the camera, or cameras, additional data, such as the color of each pixel in an image, it is possible to identify which pixels in the image correspond to the road. Once the pixels that correspond to the road are identified, the width of the road is determined, as well as the position of the vehicle on the road. With the width of the road being known, the road is “virtually” divided into virtual lanes, and it is determined which of the virtual lanes the vehicle is travelling, and the vehicle is monitored to ensure that the vehicle remains within one of the virtual lanes.
