1. A lane detection method, comprising:
sensing magnetic fields corresponding to magnetic particles included in multiple lane lines based on a magnetic sensor attached to a vehicle;
setting at least one of magnetic field correction intervals with reference to a first rate of change in the magnetic field intensity for the sensed magnetic fields;
correcting data corresponding to the magnetic field correction intervals; and
detecting multiple lane lines based on the corrected data corresponding to magnetic fields,
wherein the at least one of magnetic field correction intervals are set with reference to a second rate of change in vehicle sensor data as well as the first rate of change in the magnetic field intensity for the sensed magnetic fields.
