Abstract or Summary
  • Machine Vision has been extensively applied in industry. This thesis project, which originated with a local food processor, applies a vision system to inspection of packages for cosmetric errors. The basic elements and theory of the machine vision system are introduced, and some image processing techniques, such as histogram analysis, thresholding, and SRI algorithm, are utilized in this thesis. Computer programs written in C and Pascal are described. Hardware setup and computer interface, such as RS-232 serial interface, parallel digital I/O interface, conveyor control, and incremental shaft encoder, are described. Test results are presented and discussed.
