Claims15
An electronic device for classifying a road surface using a sound signal, the electronic device comprising:
- a transceiver configured to transmit and receive a sound signal;
- an atmosphere sensor;
- and
- at least one processor electronically connected to the transceiver and the atmosphere sensor, wherein the at least one processor is configured to:
- transmit a sound signal toward a target road surface spaced apart from the electronic device by a first distance using the transceiver,
- receive a reflection signal of the sound signal for the target road surface using the transceiver,
- acquire atmosphere information related to the sound signal using the atmosphere sensor,
- acquire first data for the received reflection signal,
- generate second data by correcting the first data based on the atmosphere information,
- acquire third data related to frequency domain information of the second data based on the second data, and
- determine a type of the target road surface based on the third data and a road surface classification artificial neural network, and
- wherein the road surface classification artificial neural network is trained as a frequency domain data set generated based on a sound signal reflected from a road surface of a second distance different from the first distance.
