Initial Situation
The quality of point clouds acquired by a mobile laser scanning system like the RIEGL VMX-450 crucially depends on the quality of the underlying platform GNSS/INS trajectory. Due to variable GNSS accuracies in thetrajectory solution the resulting point cloud shows discrepancies between overlapping scan data as well as
deviations from the true position. Manually correcting these shortcomings is a time-consuming and extremely
difficult job.

Concept of RiPRECISION MLSRiPRECISION MLS automatically conducts the whole workflow from scan data analysis to trajectory adjustment
without any user interaction. Applying highly efficient and powerful procedures RiPRECISION MLS is capable ofprocessing large amounts of data with impressively short computation times. To facilitate utmost performance,
RiPRECISION MLS has been tightly embedded into RiPROCESS.
