Machine Vision and USB

Machine vision systems are a great way for manufacturers to use advanced image capture and analysis to streamline inspection and production processes.

 

From military to medical to industrial, this technology can be applied across various industries to reduce defects, increase productivity and make manufacturing more efficient. As machine vision systems are being deployed globally, USB3 Vision cable assemblies are a top choice to support the technology.

 

USB3 Vision cables offer the ease of connection that we have come to expect from USB, with speeds fast enough to support machine vision applications.  With a data throughput rate 10 times faster than USB 2.0 (4.8 Gbps vs. 480 Mbps), USB3 Vision cables are perfectly suited to become the most popular machine vision interface.

 

The increased bandwidth substantially reduces the time required for transferring large amounts of data or video, even when supporting 4K UHD resolution. In addition to high data transmission rates, USB3 Vision cables also provide up to 4.5W of power over five meters or more and can easily be scaled to support multiple cameras.

 

Based on the USB 3.0 standard, the USB3 Vision interface uses USB 3.0 ports that are expected to become standard on most PCs in the near future. Having the plug-and-play interface readily available on most devices will make communication between devices from different manufacturers simple and easy.

 

With features including high bandwidth, ease of use, and low cost, USB3 Vision cables are ideal for machine vision applications across many sectors. To view L-com’s complete line of AIA-certified USB3 Vision cables, click here.

How USB is Shaping the Future of Machine Vision

Here at L-com we are a member of the AIA (Automated Imaging Association) trade group, the world's largest machine vision trade group. As a member we feel that it is our duty to give you some insight on how advances in USB 3.0 technology are affecting the growth of machine vision.

 

First of all-- for those who don’t already know, machine vision is defined as the methods and technology used to provide imaging-based automatic inspection and analysis.

 

Machine vision systems use cameras and image processing software to perform inspections, similar to how human inspectors on assembly lines visually inspect the quality of the products. Examples of applications where this takes place include automatic inspection, process control, and robot guidance in industry.

 

Machine vision inspection plays an important role in achieving 100% quality control in manufacturing. This reduces costs and ensures a high level of customer satisfaction. However, one of the main challenges designers face in machine vision today is market demand for HD imaging and the need for greater bandwidth based on increasing sensor resolution and frame rate.

 

Current systems are forced to compromise between image quality and compression. Higher levels of compression limit the accuracy and performance of machine vision systems.

 

But have no fear; this is where USB 3.0 comes to the rescue.

With USB 3.0, designers now have additional bandwidth at their disposal. USB 3.0 is fast -- with a 5 Gbps data rate, which is a 10x increase over USB 2.0 (480 Mbps). The increased bandwidth substantially reduces the time required for transferring large amounts of data or video.

 

As the EE Times stated it, designers can more readily increase image resolution and frame rate with greater bandwidth while still preserving image quality. Without the need for compression, designers can also reduce the amount of memory required in systems.  This translates to a lower BOM, smaller PCB, and reduced power consumption.

 

L-com offers a large variety of USB cables, and our cables are manufactured per the mechanical requirements of the USB 3.0 Vision standard. In addition to supporting the machine vision camera market, the screw mount hardware required for USB 3.0 Vision cables is beneficial in many other applications where standard USB connectors can become dislodged due to jostling, vibration, or other factors.
