According to the present invention, a method for analyzing conditions of a road surface includes the steps of: receiving, by a signal processing unit, an image signal obtained by capturing a vehicle and an audio signal, which is noise generated on the road as a vehicle runs; detecting, by the signal processing unit, an audio signal of interest in a frequency band of interest from the received audio signal to generate the audio signal of interest; and recognizing, by a recognition unit, the conditions of the road surface by analyzing the image signal and the audio signal through one of a learned vehicle type recognition model and a plurality of learned condition recognition models.

    본 발명의 노면의 상태를 분석하기 위한 방법은 신호처리부가 차량을 촬영한 영상 신호 및 상기 차량의 주행에 따라 노면에서 발생하는 소음인 오디오 신호를 수신하는 단계와, 상기 신호처리부가 수신된 오디오 신호에서 관심 주파수 대역의 오디오 신호를 검출하여 관심 오디오 신호를 생성하는 단계와, 인식부가 학습된 차종인식모델 및 학습된 복수의 상태인식모델 중 어느 하나를 통해 상기 영상 신호 및 상기 오디오 신호를 분석하여 상기 노면의 상태를 인식하는 단계를 포함한다.
