Abstract: PURPOSE: A method is provided to efficiently remove a data noise except for a lane image signal data, then to rapidly warn a driver of the deviation of a lane. CONSTITUTION: A lane image signal is processed in a binary data by photographing a lane with a camera. When the binary lane image data signal is a start, a second best group and a lane about the second best group are abstracted. Then, a lane tilt is measured and stored to output a lane width. When a vehicle is deviated from the lane, an alarm sound is generated to warn a driver. When the binary lane image data signal is not a start, a prior lane tilt is read to abstract a lane, removing a noise. Therefore, the driver is rapidly warned of the lane deviation.
