Comparison of target-and mutual informaton based calibration of terrestrial laser scanner and digital camera for deformation monitoring

Omidalizarandi, Mohammad; Neumann, Ingo (Göttingen : Copernicus GmbH, 2015)

In the current state-of-the-art, geodetic deformation analysis of natural and artificial objects (e.g. dams, bridges,.) is an ongoing research in both static and kinematic mode and has received considerable interest by ...
How significant are differences obtained by neglecting correlations when testing for deformation: A real case study using bootstrapping with terrestrial laser scanner observations approximated by b-spline surfaces

Kermarrec, Gaël; Paffenholz, Jens-André; Alkhatib, Hamza (Basel : MDPI AG, 2019)

B-spline surfaces possess attractive properties such as a high degree of continuity or the local support of their basis functions. One of the major applications of B-spline surfaces in engineering geodesy is the least-square ...
On the sensitivity of the parameters of the intensity-based stochastic model for terrestrial laser scanner. Case study: B-spline approximation

Kermarrec, Gael; Alkhatib, Hamza; Neumann, Ingo (Basel : MDPI AG, 2018)

For a trustworthy least-squares (LS) solution, a good description of the stochastic properties of the measurements is indispensable. For a terrestrial laser scanner (TLS), the range variance can be described by a power law ...
