While many interface standards are available to use in machine vision, there was still a large gap that frustrated many manufacturers, system builders and users. The industry wanted a commercial, high bandwidth, scalable solution that isn't limited in cabling length, is affordable and is true plug and play.
USB 2.0 is affordable and is certainly scaleable (up to 127 devices), but it offers a lower bandwidth and is limited in cable lengths. 1394b or FireWire™ has bandwidth a bit higher than USB 2.0 and is scalable (up to 63 devices), but is still limited in cable lengths. Camera Link® offers the highest bandwidth in industry today, but is limited in cable distance. You also pay a bit more for this high resolution.
GigE Vision™ is a new camera interface standard developed using the Gigabit Ethernet communication protocol. It represented over 2 years of work by individuals from 12 companies serving the machine vision industry. The Automated Imaging Association (AIA) oversees the ongoing development and administration of the standard.
GigE Vision™ is the first standard to allow for fast image transfer using low cost standard cables over very long lengths. With GigE Vision™, hardware and software from different vendors can interoperate seamlessly over standard Ethernet connections. The GigE Vision™ standard has four elements:
GigE Vision™ offers many benefits including:
