In order to move the CMM measurement and continue in previously inaccessible area, are measured and stored several points (3 or more). Then, after the 'leap', the car is tied to these points, thus combining a coordinate system with the previous one, and measure progress. Such jumps can be made unlimited, and over all the coordinates. This makes it possible to penetrate the most remote places and to make measurements of such complexity that implement other methods or extremely time-consuming or impossible. Hand and tracker can work together as one unit, which often requires the measurement of large objects of complex shape. Hand, in this case can be repeatedly interchanged to provide access to elements outside the field of view of a laser tracker and is used to control the situation and bring the hands of the measured data to a coordinate system. By this technology, for example, is control the assembly of aircraft at major aircraft manufacturing concerns Boing and Airbus Industry.
The laser scanner – portable system for the collection of non-contact 3D-coordinates of external objects. Scanner is ready to rotate and fix everything that is in its field of view. Scan speed – 120000 points in the second range – up to 76 m. The resulting point cloud can then be used for measurement, recognition, etc. Each type of mobile measurement systems designed to solve specific tasks. Laser scanners are used where necessary to create highly realistic 3D-models of industrial buildings, mines, pipelines, and in forensics for fixing the location of objects at the crime scene in architecture for the digitization of monuments, etc.
