A method for analyzing a road surface condition according to the present invention includes the steps of: receiving, by a signal processing part, an audio signal collected by a sensor device together with area information for distinguishing areas having different aspects of reflected sound due to a structure of a tunnel from the sensor device; generating an audio signal of interest by detecting an audio signal of a frequency band of interest corresponding to the area information from the received audio signal by the signal processing part; and recognizing a road surface condition.

    본 발명의 노면의 상태를 분석하기 위한 방법은 신호처리부가 센서장치로부터 터널의 구조에 의해 반사음의 양상이 상이한 영역을 구분하는 영역 정보와 함께 상기 센서장치가 수집한 오디오 신호를 수신하는 단계와, 상기 신호처리부가 수신된 오디오 신호에서 상기 영역 정보에 대응하는 관심 주파수 대역의 오디오 신호를 검출하여 관심 오디오 신호를 생성하는 단계와, 인식부가 학습된 노면인식모델을 통해 상기 관심 오디오 신호를 분석하여 상기 노면의 상태를 인식하는 단계를 포함한다.
