The development of a low cost digital spinneret inspection system

A low cost digital and manual spinneret inspection system is established in this paper. This system consists of a 3- axes manual stage, a telcentric lens, a top light source, a bottom light source, a CCD camera and a notebook. In this system, the system software doesn't use the commercial or open source image processing product, such as LabView, Holcon and OpenCV, it was programmed by ourselves through the Microsoft Visual C# Express. In this system, the image processing time per frame is less 30 ms, it is enough for the manual optical inspection system. Because the frame rate of this system is higher than 30 fps and it is enough for the human eyes. In the inspection procedure, all inspection results will be recorded and can be reviewed from the system. The system can add any new type spinneret by user, and can show they in a list. ? 2010 IEEE.
