With advanced 3D scanning technologies, we can now convert any physical parts into a digital model in the matter of minutes. 3D scanners collect data in the form of point cloud, and this data can be used to construct digital 3D models. The common applications of 3D scanner include reverse engineering, form & shape inspection/ quality control, virtual cinematography (movies and video games), digital archiving (cultural artefacts), non-destructive testing, and prototyping.
3D scanning technologies can generally be classified into 2 major categories: Contact and Non-Contact. CMM (coordinate measuring machine) is one of the most commonly used contact solution, it is mostly used in manufacturing and offers high precision.
