In mixed reality situations, the registration of real and virtual objects is supported by laser tracking.
In the first place the real and virtual areas are correlated referring to a global coordinate system.
Second, a reference grid is generated for the CAD system as well as for the CV.
Using the grid PMU and DMU are placed referring to the correlate grid nodes in a very fast way.
More accurate positioning is possible by using the laser tracker directly for position detection of the PMU referring to the global coordinate system.
After generating measurement points, these points are transferred to the virtual environment
and used for aligning the DMU.
