ABSTRACT

A low-cost machine vision system with hardware capabilities of image processing is developed in this research. Several image process algorithms are designed for the developed vision system, namely, image quality selection, image recovery and resize, and image segmentation. All of these mathematical algorithms are programmed and implemented in a microchip using SOPC design tools. Furthermore, the developed machine vision system is utilized in the automatic inspection process to detect the position of a compact disk in CD/DVD duplicators. In the process, the inspection algorithm is based on the two-value image provided by the machine vision system. In the near future, an attempt will be made to apply this vision system to CD/DVD label printers. Meanwhile, the integrated system has the potential usage on many low price automation products.
