Standard lenses that focus to infinity are very good when inspecting
large components, but when objects are comparable in size to that of
the imaging sensor, macro lenses are the best choice. Macro lenses are
not specified in terms of their focal length, but are named according to
the magnification. These lenses generally have a fixed working distance
and a fixed iris and are optimised for magnification with distortion
being kept to a minimum.
3D inspection is one of the latest buzzwords in the vision industry. The term 3D summarises a number of totally different acquisition and evaluation techniques that are used to gain object information that could not be easily analysed using 2D camera technology.
Le traitement d'images numérique (en anglais digital image processing) est le
terme général pour la vision et contient diverses branches comme la
publication assistée par ordinateur, le traitement des documents, jeux vidéo
et divers autres emplois.
