A Comparative Study about Data Structures Used for Efficient Management of Voxelised Full-Waveform Airborne LiDAR Data during 3D Polygonal Model Creation

Milto Miltiadou, Neill D. F. Campbell, Darren Cosker, Michael G. Grant
2021 Remote Sensing  
In this paper, we investigate the performance of six data structures while voxelising and interpreting full-waveform LiDAR data for 3D polygonal model creation.  ...  While full-waveform LiDAR data has been available for over a decade, extraction of peak points is the most widely used approach of interpreting them.  ...  Acknowledgments: The data were provided by the NERC Airborne Research and Facility (ARF). Conflicts of Interest: The authors declare no conflict of interest.  ...

Virtual laser scanning with HELIOS++: A novel take on ray tracing-based simulation of topographic 3D laser scanning [article]

Lukas Winiwarter, Alberto Manuel Esmorís Pena, Hannah Weiser, Katharina Anders, Jorge Martínez Sanchez, Mark Searle, Bernhard Höfle
2021 arXiv   pre-print
As generation and analysis of waveforms can strongly impact runtimes, the user may set the level of detail for the subsampling, or optionally disable full-waveform output altogether.  ...  HELIOS++ further allows the simulation of beam divergence using a subsampling strategy, and is able to create full-waveform outputs as a basis for detailed analysis.  ...  Acknowledgements The authors wish to acknowledge the contribution of Patrick Herbers (Ruhr-Universität Bochum), for the improvement the triangle-ray intersection in C++, which helped to significantly reduce  ...

HIERARCHICAL HIGHER ORDER CRF FOR THE CLASSIFICATION OF AIRBORNE LIDAR POINT CLOUDS IN URBAN AREAS

J. Niemeyer, F. Rottensteiner, U. Soergel, C. Heipke
2016 The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences  
We propose a novel hierarchical approach for the classification of airborne 3D lidar points. Spatial and semantic context is incorporated via a two-layer Conditional Random Field (CRF).  ...  This framework iterates and mutually propagates context to improve the classification results. Potentially wrong decisions can be revised at later stages.  ...  Xiong et al. (2011) showed how point-based and region-based classification of lidar data can interact in a pairwise CRF.  ...
