Creaform 3D scanner
The creaform Handyscan 3D Scanner is used for Metrology-grade measurements: With Precisions of up to 0.030 mm (0.0012 in.), resolution of up to 0.050 mm (0.002 in.), high repeatability and traceable certificate. Highest measurement rate among all laser scanners: 480 000 measures/s. Stand-alone device: There is no need for an external positioning system, arms, tripod or fixture.Use on Reaserch and Eduacation, Aerospace, Automotive and transport and manufacturing

Fig 2 Initial Calibration is needed before the scanning process
Fig 3 The calibration display is shown
Fig 4 Physical targets were needed to be place on the model in order to identify points on the cloud before to scanning.
Fig 5 When scanning, the first things shown on the display were the target location
