Today 3D machine vision is most commonly used for the precise three-
dimensional inspection and measurement of complex 3D free formed surfaces, but
new fields of applications are constantly being explored.
Camera manufacturers include a wide range of functions in their
products to meet the increasing demands of the industrial market.
Some of the key camera characteristics and common features are
discussed in this section.
Interfacing cameras to computers for image processing has changed
significantly in the last few years. In recent years the industry put a lot of
effort into standardisation and several standards such as CameraLink,
DCAM/IIDC and GigE Vision emerged. In addition GenICam has been approved,
offering genuine ‘plug and play’ functionality for industrial vision cameras.
CameraLink HS has a long history even though the standard itself is
young. With the ever increasing camera speeds "classic" CameraLink
standard is not able to scale easily beyond 850 MB/s, so another new
interface was needed to meet the needs of ever higher bandwidths at
the same or even lower cost.
