Collected 3D data is useful for a wide variety of applications. If colour information is collected at each point, then the colours on the surface of the subject can also be determined. faro laser tracker user manual pdf scanners share several traits with cameras.
3D scanner collects distance information about surfaces within its field of view. The “picture” produced by a 3D scanner describes the distance to a surface at each point in the picture. This allows the three dimensional position of each point in the picture to be identified. For most situations, a single scan will not produce a complete model of the subject. Multiple scans, even hundreds, from many different directions are usually required to obtain information about all sides of the subject. This whole process, going from the single range map to the whole model, is usually known as the 3D scanning pipeline. There are a variety of technologies for digitally acquiring the shape of a 3D object.
