The new USB3 Vision protocol is based on the standard USB3.0 interface. With USB3.0 ports now being standard on most PCs providing high bandwidth and easy ‘plug and play’ connectivity.
Until now there has been no real standard for USB devices in the Machine Vision industry. Traditionally, USB in Machine Vision and related markets has only been defined by the physical interface (connectors, cables, etc.). So USB cameras have existed as proprietary implementations by individual camera manufacturers. While this may suffice in some cases, it can limit the customer in terms of compatibility and selection. History has shown that for an interface to become truly successful and widely implemented, a global standardisation of the interface for Machine Vision usage is critical. These standards take into account the unique needs of Machine Vision regarding hardware, software, and accessories. USB 3.0 provides the industry with a more viable interface than USB 2.0 ever was. Therefore, it has been decided to create a Machine Vision standard around USB 3.0 called USB3 Vision.
USB 3.0 Vision will soon become an important interface for machine vision cameras used in industrial, medical and mass-market applications. It supports bandwidth speeds in excess of 300MB/s and is designed to be plug-and-play, creating a very fast and easy to implement alternative to IEEE1394 (Firewire) technology, making USB 3.0 a major mainstream interface to compliment GigE Vision.
Amongst others Basler have been working on standardising USB 3.0 interface for vision applications, contributing personnel and technical expertise to the AIA committee. Basler will launch their ace USB3.0 interface cameras, based on the USB3 Vision Standard. The new ace USB3 models continue to be small (29mmx29mm) with a great low price and high performance.
