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.
One of the most common applications for inspecting manufactured components is gauging. Similar to using a physical calliper or rule, a gauge tool can measure distances and angles between edges. More advanced tools can report measurements between centres of circles and the spacing of repeating forms and edges, such as gear teeth.
The GenICam standard (GENeric Interface for CAMeras) provides generic software
interfaces for all kinds of machine vision cameras whatever their hardware
interface. The underlying interface used, for example, GigE Vision or
CameraLink, is of no relevance. New technologies such as Camera Link HS, CoaXPress, or USB3 Vision, also rely on the GenICam standard.
Image distortion can be caused by many factors such as lens distortion (see the optics section), or when the camera views a target at an angle to the image plane. Geometric correction is very processor intensive, but can be essential in some applications to obtain a usable image.
