Point Cloud Registration

Point clouds of different runs will always have a deviation between them. This problem is solved by a procedure called point cloud registration – the process of repairing the accuracy of the point cloud position, or merging clouds of points from different runs into a unique point cloud. Control measurements obtained by classical geodetic methods may be included in the data processing, which are implied to have better accuracy. Using control measurements to improve the accuracy of the data leads to a procedure called georeferencing.
