| Abstract: | An on-line inspection system was developed for wide film (width: 1 300 mm) production, which is able to detect the defects on the film surface. The system consists of two sets of 8 Kpixel high-resolution linear CCD cameras and an infrared illumination source with 940 nm LED. Then the images captured by two cameras are processed synchronously using single line processing and multiple lines judgment algorithm. Field operation shows that running at a high speed of 90 m/min, the system is able to detect the surface defects of wide film with the width of 1 300 mm in real time and operates normally. |
