GigE Article in Vision & Sensors 9.01.08
Interfacing cameras to computers used to be a challenge. In the 1980s, when machine vision was in its infancy, most cameras used analog interfaces based on closed-circuit TV (CCTV) standards such as RS-170. Analog camera data was sent as composite video down coaxial cable and digitized by frame grabber hardware that was built into special hardware dubbed a “machine vision system.”
In the 1990s, digital cameras proliferated, but most digital cameras used parallel data transmission, requiring cumbersome and quite short, expensive cables. Toward the turn of this century, PC-centric networking topologies like USB and IEEE-1394/FireWire became more and more universal and offered a tantalizing taste of what easy machine vision might be like.
But now... there is a great new alternative.
