According to the present invention, a crack detection system for a road can comprise: a photographing unit installed on one or more of a vehicle and a drone, and photographing the road, and collecting image information and position information of the road; a pre-processing unit dividing the image into a preset patch size, and setting a region of interest (ROI), and extracting a plurality of patch images included in the ROI; a crack patch image detection unit classifying patch images with a crack on the road among the extracted patch images by using an artificial neural network; a conversion unit converting crack information included in the classified crack patch images into a preset color; and a crack rate measuring unit measuring the number of pixels on the parts converted into the preset color, and measuring the crack rate of the road in the crack patch images, and making data of and saving the position information and the crack rate information included in the crack patch images. Therefore, the crack rate of a road can be more rapidly and precisely detected.

    본 발명에 따른 도로의 균열 검출 시스템은 차량과 드론 중 적어도 하나에 설치되어 도로를 촬영하고, 상기 도로에 대한 영상 정보와 위치 정보를 수집하는 촬영부; 상기 영상을 기설정된 패치(Patch) 사이즈로 분할한 후, 검출영역(ROI: Region Of Interest)을 설정하여 상기 검출영역에 포함된 복수의 패치영상을 추출하는 전처리부; 인공신경망을 이용하여 상기 추출된 패치영상들 중에서 도로에 균열이 있는 패치영상을 분류하는 균열 패치영상 검출부; 상기 분류된 균열 패치영상에 포함된 균열 정보를 기설정된 색상으로 변환하는 변환부; 및 상기 기설정된 색상으로 변환된 부위의 픽셀 수를 측정하여 상기 균열 패치영상에서 도로의 균열률을 측정한 후, 상기 균열 패치영상에 포함된 위치 정보 및 균열률 정보를 데이터화하여 저장하는 균열률 측정부;를 포함할 수 있다.
