Abstract
Disclosed herein are a method and apparatus for recognizing driving information using multiple sensors. The method for recognizing driving information according to an embodiment of the present disclosure includes generating a magnetic sensing signal from magnetic paint applied to road markings, generating a frequency-converted signal using the magnetic sensing signal, and generating driving information for a vehicle using the frequency-converted signal.
Claims12
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.
