이후, 카메라를 이용하여 피 검사체를 촬영하고, 촬영된 이미지를 바탕으로 이물 및 불량 여부를 검사하는 비전 검사시스템이 개발되어 그 수요가 크게 증가하고 있다.Thereafter, a vision inspection system for photographing an object to be inspected using a camera and inspecting whether there are foreign substances and defects based on the photographed image has been developed, and the demand thereof is greatly increased.

반면, 비전 검사를 실시하면서, 가시광선을 조사하여 진행할 수 있는 검사에는 외형 검사나, 컬러 또는 명암 검사 등이 있으며, 표면에 형성된 각인이나, 지문과 같은 표면의 오염이나, 이물의 검사는 어려운 문제점이 있었다.On the other hand, while conducting a vision inspection, inspections that can be performed by irradiating visible light include appearance inspection, color or contrast inspection, etc., and it is difficult to inspect a foreign object, such as imprinting on the surface, contamination of a surface such as a fingerprint, or foreign matter. There was.

이에 따라, 한국등록실용신안 제20-0297859호 "표면 검사용 조명장치"과 같이 복수의 발광소자들을 다수의 구역으로 분할하여서 각 구역별로 선택적으로 발광시켜 결함부분에서 발생되는 명암대비를 이용하여 보다 정밀하게 검사체 표면에 발생된 결함 유무를 검사하기 위한 시스템이 개발되었다.Accordingly, by dividing a plurality of light emitting elements into a plurality of zones, such as the Korean Registered Utility Model No. 20-0297859 "Surface Inspection Lighting Device", it is possible to selectively emit light in each zone to use contrast contrast generated in the defect area. A system for precisely inspecting the presence or absence of defects generated on the surface of an object has been developed.

하지만, 여전히 피 검사체의 이물이나, 오염, 표면의 긁힘, 표면에 형성된 각인의 품질을 정확하게 구분하지 못하고, 피 검사체의 전 방위에 걸친 검사가 어려운 문제점이 있었다.However, there is still a problem in that it is difficult to accurately distinguish the quality of the foreign matter, contamination, scratches on the surface, and the quality of the imprint formed on the surface, and it is difficult to inspect the entire direction of the object.

이에 따라, 피 검사체의 이물이나, 오염, 표면의 긁힘, 표면에 형성된 각인의 품질을 전 방위에 걸쳐 검사를 실시하기 위한 기술 개발의 필요성이 제기되고 있다.Accordingly, there is a need to develop a technique for inspecting foreign objects, contamination, scratches on the surface, and quality of imprints formed on the surface of the object to be inspected in all directions.
