3d Laser Scanners: History and Applications

Abstract: A 3D scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance (i.e. color). The collected data can then be used to construct digital three-dimensional models. 3D laser scanning developed during the last half of the 20th century in an attempt to accurately recreate the surfaces of various objects and places. The technology is especially helpful in fields of research and design. The first 3D scanning technology was created in the 1960s. The ear… Show more

“…The next step in 3D scanning was the integration of digital technology, which began during the 1960s [42], but an increasing trend of "3D scanning" can be found in papers and articles after the 1990s when computers started to become much more powerful (Figures 8 and 9). The first 3D scanning of large statues can be found in the report of "The Digital Michelangelo Project: 3D Scanning of Large Statues" by the University of Stanford, in 2000 [43].…”

“…A 3D szkennelés technológiája nagyban leegyszerűsíti ezt a folyamatot. Az 1960-as évektől kezdve (Edl, 2018) számos különböző módszer alakult ki, a "tapogatós" szkenneléstől kezdve, ahol egy tapintófejet folyamatos kontaktusban tartva a munkadarabbal kell azt végigpásztázni, az optikán alapuló fehérfényes szkennelésen át egészen a lézerrel működő gépekig. Az optikai szkennerek működési alapelve a fókusztávolságban rejlik, két különböző pozícióból készítenek képet a tárgyról, majd a két fókuszpont közötti eltérésből kiszámítják a távolságot.…”

“…Az optikai szkennerek működési alapelve a fókusztávolságban rejlik, két különböző pozícióból készítenek képet a tárgyról, majd a két fókuszpont közötti eltérésből kiszámítják a távolságot. A lézeres szkennerek szenzorral mérik a lézerfény visszaverődésének időtartamát, és ebből számítják minden egyes pont távolságát a mérőegységtől (ehhez természetesen szükség van a mérőegység aktuális helyzetére is) (Edl, 2018).…”

“…3D scanning technologies substantially simplify this process. Since the 1960s, numerous methods have been invented [2]. At first, contact probes were used to measure each point of a surface, which were then saved as coordinates with regard to the machine coordinate system.…”

“…A more advanced method uses laser beams and sensors to calculate these lengths based on the speed of the beam and the duration of the reflection from the surface. The * Correspondence: almos99@freemail.hu current position of the device is also required [2]. None of these methods requires physical contact with the object.…”
