Abstract
In a method for detecting lane deviation of a vehicle, a difference between a center point of lane markers and a center point of the vehicle is first determined. Then a difference between a screen center x-coordinate and a vehicle center point x-coordinate is subtracted from the determined difference between the center point of lane markers and the center point of the vehicle. And it is determined that the vehicle is deviating from the lane if the result of the subtraction is less than a predetermined value.
