1. An image processing method comprising the steps of:

  • generating a road image by photographing a road on which a vehicle is traveling;

    performing a brightness averaging process of the road image;

    filtering the road image having undergone the brightness averaging process to detect lane markers;

    performing an inverse perspective process on the filtered road image;

    compressing the road image having undergone the inverse perspective process in a vertical direction;

    determining slope in the lane markers from the compressed road image;

    determining a curvature in the road from the determined slope in the lane markers; and

    determining a drive direction and a lateral lane deviation of the vehicle.
