In the present invention, an apparatus for estimating road surface information and a method thereof are disclosed to improve the accuracy of road surface information so as to improve the suspension performance. The apparatus for estimating road surface information of the present invention includes a vehicle status input unit for receiving a vehicle status and a road surface height from a vehicle height detection unit, a behavior detection unit, and a front camera module; and a control unit for converting the coordinates of a camera according to vehicle behavior based on the vehicle height input from the vehicle status input unit to compensate for the road surface height and a perceived road surface distance, and estimating road surface information by matching and filtering a plurality of road surface heights.

    본 발명은 노면 정보 추정 장치 및 그 방법이 개시된다. 본 발명의 노면 정보 추정 장치는, 차량의 차고 감지부, 거동 감지부 및 전방 카메라 모듈로부터 차량의 상태와 노면높이를 입력받는 차량상태 입력부; 및 차량상태 입력부로부터 입력된 차고를 기반으로 차량 거동에 따른 카메라의 좌표를 변환하여 노면높이와 인지 노면거리를 보상하고, 다수의 노면높이를 매칭시켜 필터링하여 노면정보를 추정하는 제어부;를 포함하는 것을 특징으로 한다.
