Applied Image Processing
Module No. UEP053HM
Tutor: Dr. Mel Smith
Aims of the course
- To offer a practical introduction to applied image processing, for a potential system user/integrator.
- To provide an understanding of the importance of a visual sense, within the manufacturing cycle.
- To explore the justification for applied image processing.
- To consider the interfacing of vision equipment in a computer integrated manufacturing environment eg: RS232, robotic guidance, data acquisition, closed loop/process control.
- To provide an awareness in potential improvements in safety, reliability, flexibility and product quality, within the manufacturing process.
- To consider economic justifications for vision applications.
