USB 3.0 Camera Solutions for Machine Vision

With their high speed, acceleration and handling, supercars provide a thrilling level of performance which leaves many of us in wonder and amazement. However, supercars do have their disadvantages due to a lack of visibility, difficulty getting into the car and highly sensitive controls.

As a result, people may prefer to use a more reliable, comfortable and compact car for their daily commute rather than using their supercar as the compact car is easy to operate, provides more comfort and has a much better fuel efficiency.

How can you enjoy the best of both worlds?  

In machine vision, USB 3.0 can be thought of as a high-performance supercar which combines all of the benefits of a compact car.

The Benefits of USB 3.0

With user-friendly consumer oriented technology, USB 3.0 offers a high-speed data interface without the need for expensive cabling, specialized frame grabbers or tedious software installation. USB 3.0 is an advanced version of USB 2.0, one of the most widely used data interfaces currently available.

One of the most attractive features of USB 3.0 for machine vision systems is the high bandwidth which offers a transfer speed around 5Gb/s. This transfer speed is ten times higher than that of USB 2.0 and five times higher than the widely used GigE interface.

However, USB 3.0 is dependent on 8b/10b data encoding for embedding bus timing information within the data, meaning that not all of the transfer speed is usable. Nevertheless, the effective payload data rate of USB 3.0 still stands at 4Gb/s, even after taking this dependency into account.

The data transfer speed of USB 3.0 is effectively nearing the speed of specialized machine vision interfaces such as CoaXPress and CameraLink. However, USB 3.0 requires no special interface cards or frame grabbers in the host computer unlike these two interfaces.

USB 3.0 provides a truely plug-and-play experience as it is already integrated into most modern computers. The widespread adoption of USB 3.0 has allowed the maturity of the standard to a solid, reliable computer peripheral bus with access to a wide range of devices.

The availability of a variety of computer platforms and operating systems allows USB 3.0 to offer flexibility to system designers, thereby facilitating the deployment of complex machine vision systems.

Some people believe that the length of cabling used to connect a device to the host is limited to 5 metres by USB 3.0.

However, this is not true due to that fact that many cable vendor produce cables and extender solutions which are capable of supporting distances of more than 300 metres.

In fact, there are very few applications in which USB 3.0 is not good enough to satisfy the requirements for the bulk of machine vision, ITS and UAV.
