I work for a company that is evaluating to start the development of generic vision inspection systems, in-house. We expect to develop around 50 such machines in the next five years. So far we need to explore the basic factors that would lead to success:

  • When is it justified to develop such systems in-house, as opposed to going with off-the-shelf devices?
  • What are the skills we should be looking for in developers?
  • What is the equipment normally used? (lighting, cameras, computer or controller...)

The typical tasks we would be doing include: Component presence detection, component recognition, physical measurements, surface inspection, reading bar codes, and finding components in the physical space to guide pick-and-place robots.

We work in an industrial environment with production sites spread over the world, so reliability and robustness is something we must consider.

As an actual example, one of the applications includes measuring a 50mm, dark circular component which has a tolerance of 0.02mm. How would you go around this problem?
