Design of machine vision system for high speed manufacturing environments

In today's competitive markets, industries have to focus on quality of their products to retain their competitive edge. Automatic Optical Inspection (AOI) or Automated Visual Inspection (AVI) is one commonly used tool used in the industry for quality control and monitoring. In high speed mass production units, the inspection time available for each product is small and it becomes a critical design constraint while staging a vision system. This paper proposes techniques that can be employed at different stages of setting up a vision system to achieve the required high rates of inspection. The design methodology for developing inspection algorithms considering the time constraint is discussed in this paper.
