- Abstract
A current aim of ongoing research in the field of deformation measurement is to automatically determine geometric changes between several epochs with data captured by terrestrial laser scanners. A critical component within the process chain of deformation measurement is the transformation of captured point clouds into a reference coordinate system. This contribution proposes a surface-based alignment methodology that does not require artificial targets or extracted geometric primitives. A diagnostic method reveals deformations that occurred in between epochs and rejects them from the computation of transformation parameters that would otherwise cause erroneous registrations. The novel approach has been successfully tested on two practical cases where the highest degree of deformation extended to 65% of the total surface area.
