Designing an automated, inline system to perform final quality inspection of a large or complicated assembly can be tricky. Each individual machine vision task can be handled easily enough, but there are often complicating factors.
For example, a single vision sensor may lack the pixel resolution to capture all the features of the assembly, or the application may require inspections to be made at various locations on the assembly. In either case, the system would need multiple cameras, and that means more space and a more challenging integration project. To further complicate matters, the system is typically called upon to inspect multiple SKUs on the same line.
