Devices known as Acquisition Modules, based on digital interfaces like
USB, FireWire and Gigabit Ethernet. These compact, external modules behave like an external frame grabber, having an interface to one or more cameras at one end and an output to one of the digital interfaces on the other (USB, FireWire or
Gigabit Ethernet) and are used for transferring data to a PC.
This Tech Tip is designed to re-visit the camera interfaces and transmission
standards available for vision systems. Since the last Tech tip on this
subject, over four years ago, there have been a number of new developments.
Chemical Colour Imaging (CCI) makes complex hyperspectral data on a molecular level usable for machine vision. Hyperspectral imaging systems from STEMMER IMAGING based on a generic, intuitive configurable data processing platform developed by Perception Park make the scientific methods of hyperspectral analysis accessible for everyone and open up new application areas.
Is your machine vision system struggling to handle large amounts of data provided by high resolution and high frame rate cameras? Are you are planning a complex high-speed vision system and don't know how to get real time results? You can speed up your vision system with high-performance frame grabbers from Silicon Software. Our experts can tell you how and help you get your system up and running!
In principle, every image processing system consists of two basic function units: the image source and the image sink. Today compact CMOS cameras are usually used as the image source in the industrial imaging environment. The image sink is the processing unit that extracts results from the image. Currently this will most likely be a classic PC system based on Intel processors and the Windows operating system.
Imaging is an enabling technology in a vast range of industries. No longer
confined to traditional manufacturing and processing inspection applications,
industrial vision finds applications in industries as diverse as security,
transport, sport, space exploration and even as part of the attempt to set a
new world land speed record in 2015.
LED lighting offers many advantages including ease of use, excellent
flexibility of design, medium to high intensity output, long life and very
good reliability and repeatability - all major benefits when putting together
a vision system.
Gigabit-Ethernet for Machine Vision or, in short, GigE Vision: According to
many experts, the new interface standard and the closely associated generic
software interface GenICam (Generic Interface for Cameras) will give new
impetus to the industrial image processing sector in the near future: The
image processing industry finds itself at a crucial technological watershed!
When implementing an image processing solution, the selection of suitable
illumination is a crucial element in determining the quality of the captured
images and can have a huge effect on the subsequent evaluation of the image.
Despite this, choosing the best light source for an application is often among
the most fraught tasks in image processing and is quite often neglected - to
the detriment of the overall system.
