FEATURES

As the demands on machine vision continue to increase, the last year has seen two distinct phenomena: The rise of the so-called "smart camera" and the push to develop networked camera systems. These two megatrends in industrial vision are the result of a unique interplay of factors - both economical and technological. Manufacturers are demanding more and more speed; image preprocessing and frame storage, yet have grown leery of the hefty price tags associated with these systems. As cameras come...
