Abstract

The computer vision-based valve control system and method includes a camera mounted on a pneumatic control valve in such a way that the camera periodically observes positioning of the valve stem. An image processor is applied to the output of the camera to determine percentage opening of the valve. The valve opening percentage of the image processor is fed to a PID controller that uses the valve opening percentage in its process control calculations.
