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!
Hyperspectral imaging provides its users with a high-performance possibility to determine differences in the chemical composition of test objects. This technology opens up interesting applications in areas such as recycling or food production.
Inspection is a critical component of HACCP programs in the food industry. Hyperspectral imaging now provides a powerful complementary approach for the machine vision engineer. Its ability to identify differences in the chemical composition of organic materials opens up major new possibilities for detecting impurities in food products. Most importantly, systems are now available that operate in real time, allowing them to be used on high speed production lines.
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.
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.
In any camera-based application the illumination is a critical part of the
system. At the most basic level, there must be enough light so that the camera
can acquire a good image. Beyond this it is almost always necessary to use the
orientation, geometry or colour of light to highlight relevant details or
minimise the appearance of unhelpful parts of the image, such as glare.
Getting the illumination right simplifies analysis, indeed it may be critical
to an inspection.
There are many different ways of increasing image processing speed. In the
latest version of Common Vision Blox, STEMMER IMAGING has adopted a new
method: offloading parts of the processing to the PC`s graphics card, which
can boost the speed of some functions by up to a factor of 10.
A focus group of machine vision industry leaders, chaired by the VDMA, recently reported that emerging technology would influence the sector in some significant areas. These included new applications being made possible by advances in new vision technology coming to market, and an increase in machine vision users as vision technology becomes easier to use.
FPGAs used for data conversion is wide-spread and generally unseen by the user
but when they are brought to the forefront of processing, they have the ability to offload processing power from the CPU and can enable extremely high bandwidths.
