LANE DEPARTURE WARNING SYSTEM AND LANE DEPARTURE WARNING METHOD

摘要

The present invention provides a lane departure warning system including: an image photographing part which is attached to the front of a vehicle and photographs the front of the vehicle; a driving part which finds out a pair of lanes by filtering the image data by a mask by receiving the image data from the image photographing part, and generates a warning generation signal according to lane departure time by calculating the lane departure time from the pair of lanes; and a warning part which generates a lane departure warning signal by receiving the warning generation signal. Therefore, the system can improve its speed by making a searching part and a tracing part have different interested area when the system extracts lane characteristics by extracting an interested area from the image, and can be used in case that there is more than one lane, and can detect a lane without regard to the external environment.
