Paper Abstract

An application case history is detailed where machine vision was implemented in a closed loop process control setting. Specifically, a machine vision system was used to measure dimensions on aseptic packaging. These dimensions were then compared to a nominal value and an error signal was generated based on the measurement deviation from nominal. This error signal was generated by the vision system in the form of a minus 10 V dc to 10 V dc analog signal proportional to the measurement deviation. In addition, the application made use of low angle lighting techniques, normalized correlation, and automatic part changeover and calibration.
