Biased and unbiased estimates based on laser scans of surfaces with unknown deformations
(2014-10-02)
The estimates based on laser scans of surfaces with unknown deformations are biased and not reproducible when changing the scanning geometry. While the existence of a bias is only disadvantageous at some applications, ...
Automatic optimization of height network configurations for detection of surface deformations
(2013-05-18)
Levellings are performed to observe height changes of different epochs at discrete surveying points. A
reliable estimation of surface deformations by a bivariate polynomial needs a sufficient configuration of the underlying ...
