Scanning system takes 3-D laser scanning into fields not possible in the past.
NVision (Wixom, MI) has introduced a mobile laser scanner that is light and portable, yet can create a noncontact, 3-D scan of an object as accurately as a coordinate measuring machine (CMM). The new high-definition version of MobileScan 3-D laser scanning system moves the capability of 3-D laser scanning to fields not accurate enough in the past. The new high definition (HD) scanner provides high resolution with a point spacing of 0.001 inch and an accuracy of ±0.0005 inch while collecting measurements at a rate of 30,000 points per second.
Portable laser scanners are typically arm-mounted or completely stationary. They are capable of collecting many thousands of points per second but lose accuracy either through the seven axes of movement in the arm or the process of building a 3-D picture from separate "shots" from a stationary camera. The system is programmed to use only one of its three axes of movement at any time in a controlled manner. This way it can collect 3-D data in a single scanning session with CMM levels of accuracy. All measurements are automatically transformed into a common coordinate system in Geomagic software, meaning that there are no patches of data to be sewn together after scanning has taken place.
