1. A method for recognizing driving information, comprising:
generating a magnetic sensing signal from magnetic paint applied to road markings;
generating a frequency-converted signal using the magnetic sensing signal;
generating driving information for a vehicle using the frequency-converted signal; and
detecting a vibration frequency by a vibration sensor installed in the vehicle while the magnetic sensing signal is being generated
wherein the magnetic sensing signal includes a first magnetic sub-signal generated from the magnetic paint through a first magnetic sensor and a second magnetic sub-signal generated from the magnetic paint through a second magnetic sensor,
wherein the frequency-converted signal is generated using an additional noise-reduced signal acquired by further removing noise corresponding to the vibration frequency from the noise-reduced signal generated using a difference between the first magnetic sub-signal and the second magnetic sub-signal.
