3D scanning interprets real items or environments into digital, three-dimensional models. It's purpose lies in the surveying and then making geometric samples on areas of the subject, and these precise points are used to represent the subject. As soon as this process is performed, the picture enables the laser to include colour. Given the accuracy, reproduction of information is 1 of the laser scanner's major promoting points of this technology.

In the digital world of scanning presently there are two sorts of classifications: contact as well as non-contact scanning devices. Non-contact scanners can further be categorized into active as well as passive.

Contact Scanners

Contact three dimensional scanning devices use physical contact to analyze the subject, and are mainly used to manufacture items. 1 of the most widely-used good examples of a contact 3 dimensional scanning device could be a Coordinate Measuring Machine (CMM). The disadvantage of this technology, is that it, depends on the contact with the object, as a simple act of scanning an item may harm it. This regrettable circumstance ...
... is especially very important whenever scanning historical items. These CMM's are relatively slow compared to laser scanning devices, because the latter may operate from ten to 500 kHz, in comparison to contact 3D scanners' a few 100.
