Classification of Terrestrial Laser Scanner Point Clouds: A Comparison of Methods for Landslide Monitoring from Mathematical Surface Approximation

Kermarrec, Gaël; Yang, Zhonglong; Czerwonka-Schröder, Daniel (Basel : MDPI, 2022)

Terrestrial laser scanners (TLS) are contact-free measuring sensors that record dense point clouds of objects or scenes by acquiring coordinates and an intensity value for each point. The point clouds are scattered and ...
How to account for temporal correlations with a diagonal correlation model in a nonlinear functional model : A plane fitting with simulated and real TLS measurements

Kermarrec, Gaël; Lösler, Michael (Berlin [u.a.] : Springer, 2021)

To avoid computational burden, diagonal variance covariance matrices (VCM) are preferred to describe the stochasticity of terrestrial laser scanner (TLS) measurements. This simplification neglects correlations and affects ...
