Disclosed are a system for inspecting a lower part of a vehicle and a method thereof. In accordance with an embodiment of the present invention, the system for inspecting a lower part of a vehicle in an inline process includes: a vehicle recognition part recognizing a vehicle moving into an inspection process to acquire a vehicle ID; a vision system located in a lower part of a moving direction (Y-axis) of the vehicle and photographing an image of the lower part of the vehicle through a plurality of cameras placed at vertical and diagonal angles in a width direction (X-axis) of the vehicle; and an inspection server detecting an assembly defect of an automotive part by performing at least one among a first vision inspection of operating the vision system based on setting information suitable for a vehicle type and specifications in accordance with the vehicle ID to acquire the photographed image of the lower part of the vehicle to match object images by object through a rule-based algorithm, and a second deep learning inspection using a deep learning engine.

    차량 하부 검사 시스템 및 그 방법이 개시된다. 본 발명의 실시 예에 따른, 인라인 공정의 차량 하부 검사 시스템은, 검사 공정으로 진입하는 차량을 인식하여 차량 ID를 획득하는 차량 인식부; 차량 이동방향(Y축)의 하부에 위치하며 상기 차량의 폭 방향(X축)을 따라 수직 및 대각선 각도로 배치된 복수의 카메라를 통해 차량 하부 영상을 촬영하는 비전 시스템; 및 상기 차량 ID에 따른 차종 및 사양에 맞는 설정정보로 상기 비전 시스템을 작동하여 촬영된 상기 차량 하부 영상을 획득하여 룰기반 알고리즘을 통해 부품 별 객체 영상을 매칭하는 1차 비전 검사와 딥러닝 학습 엔진을 통한 2차 딥러닝 검사 중 하나 이상을 수행하여 부품의 조립 불량을 검출하는 검사 서버를 포함한다.
