Make sure to replicate the changing light patterns on a plant floor when testing a vision system. It is important, however, to make sure that the prospective system is able to recognize both marginally good and marginally bad parts from the mixture. And, make sure that the vision system vendor has a complete understanding of what you want to accomplish. Although vision systems have incredible capabilities, it is important to avoid unreal expectations when integrating them into your production process. Start with a task that you can easily monitor and accurately chart the system's success.
Vision systems are typically capable of performing more than one task upon each part view.
Experiment with the software and add inspections to the system once it is on line. All advances in software and user-friendliness aside, machine vision is still a technology requiring a lot of knowledge to be applied correctly. At the very least a company specializing in industrial vision systems should install the first system. So PCB makers have been looking for new technologies to avoid shipping faulty boards. One of the most recent technologies integrates the concepts of vision to accomplish the task of inspecting and troubleshooting board error locations.
