Information

The visual control system of AOI automatic optical inspection systems is mainly composed of CCD industrial cameras and light sources.

How to select a CCD camera correctly?

The camera of an AOI automatic optical inspection system is classified into area-array cameras and line-scan cameras according to the mode of capturing an image. The area-array camera is used to take a picture of one image; the line-scan camera scans in a line-by-line mode. The advantage of the area-array camera is that the image is reducible, the lighting angle is easy to adjust, and it is easier to get a clearer image. Most manufacturers of AOI automatic optical inspection systems use this type of cameras. Line-scan cameras have poor image reducibility, and it is difficult to adjust the angle of lighting. This type of AOI automatic optical inspection system has the highest misjudgment rate. The only advantage of AOI automatic optical inspection system using this kind of camera lies in the fact that the detection speed is higher. However, the speed of detecting small boards is lower. Therefore, when selecting the camera, it’s best to choose the area-array camera.
