Zusammenfassung:The present invention relates to a concrete crack detection system using 2D and 3D configuration, and more specifically, to a concrete crack detection system using 2D and 3D configuration for identifying and detecting a crack through image analysis. The concrete crack detection system prevents misdetection, in which a foreign material or the other error condition of the image is recognized as a crack, by using depth information through 2D image and 3D shape data analysis when a crack is generated on an upper part of concrete. The concrete crack detection system verifies the analysis on the crack location by using height information of 3D inspection to confirm misdetection due to the foreign material in 2D image crack analysis process. The concrete crack detection system comprises: an inspection device which obtains a 2D image and 3D shape information; a collection device having a data collection analysis device; and a tachometer which synchronizes distance to the inspection device. 본 발명은 2D 및 3D 구성을 이용한 콘크리트 균열 검측시스템에 관한 것으로, 이미지 분석을 통해 균열을 인식하고 검측하기 위해 2D 및 3D 구성을 이용한 콘크리트 균열 검측시스템에 관한 것이다. 2D 이미지와 3D 형상 데이터 분석을 통해 콘크리트 상부에 균열 발생시 깊이 정보를 이용하여 이물질이나 기타 이미지 상 에러 조건을 균열로 인식하는 오검출을 해결하고, 2D 이미지 균열 분석 과정에서 이물질에 의한 오검출을 확인하기 위해 3D 검사에서의 높이 정보를 이용하여 균열 위치에 대한 분석을 검증하는 효과가 있다.
