Escáneres ópticos 3D de mano en ingeniería inversa

Data acquisition is a key part in any reverse engineering process. When measuring mechanical components, or any physical object, there are numerous methods to perform this phase, but handheld 3D scanners are among the most popular. Compared to static scanners, handheld scanners have the advantage of being easier to transport and use. The present article contains a brief description of reverse engineering and an analysis of the three technologies that make handheld 3D scanners possible. Examples of the most innovative devices within each category are included and the positioning methods of optical 3D scanners are discussed.This article aims to bring together the latest information on handheld optical scanners and their technologies in order to facilitate the choice of the most suitable method for each application.
