Learn more about machine vision! In our knowledge base we are explaining key technical terms about image processing. We give you an overview to topics like 3D machine vision or the established standards like CameraLink, GigE Vision or GenICam.
Illumination usually needs to be controlled in some way. Lights can be strobed
or pulsed, the intensity can be raised or lowered or, in a more complex set-
up, different lighting scenarios can be pre-programmed using a lighting
controller so a combination of images can be used to perform a reliable
Most European countries have very strict rules concerning the use of
lasers. As lasers are commonly used for test or placement applications
in machine vision, it is very important to be aware of the safety
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.
There are many arithmetic operations that can be performed on images. These work on a pixel-by-pixel basis; reading one or more pixel values, performing an arithmetic function on the pixel and exporting the result as an output image.
