SimTreeLS: Simulating aerial and terrestrial laser scans of trees [PDF]

open access: yesComputers and Electronics in Agriculture, 2021
There are numerous emerging applications for digitizing trees using terrestrial and aerial laser scanning, particularly in the fields of agriculture and forestry. Interpretation of LiDAR point clouds is increasingly relying on data-driven methods (such as supervised machine learning) that rely on large quantities of hand-labelled data.

Semi-Automatic Registration of Airborne and Terrestrial Laser Scanning Data Using Building Corner Matching with Boundaries as Reliability Check

open access: yesRemote Sensing, 2013
Data registration is a prerequisite for the integration of multi-platform laser scanning in various applications. A new approach is proposed for the semi-automatic registration of airborne and terrestrial laser scanning data with buildings without eaves.

MULTI-PASS APPROACH FOR MOBILE TERRESTRIAL LASER SCANNING [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Mobile Terrestrial Laser Scanning (MTLS) has been utilised for an increasing number of corridor surveys. Current MTLS surveys require that many targets be placed along the corridor to monitor the MTLS trajectory’s accuracy. These targets enable surveyors

Green-wavelength terrestrial laser scanning of mountain channel [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
It is crucial to understand and predict how the water and sediment flow in mountain channels for better disaster risk management. Detailed and quantitative measurement of channel and stream-bed structure is in great demand. In this paper, the utility of

Consequences of vertical basic wood density variation on the estimation of aboveground biomass with terrestrial laser scanning

open access: yesTrees, 2021
Key message Stump-to-tip trends in basic wood density complicate the conversion of tree volume into aboveground biomass. We use 3D tree models from terrestrial laser scanning to obtain tree-level volume-weighted wood density.

Using terrestrial laser scanning for characterizing tree structural parameters and their changes under different management in a Mediterranean open woodland

open access: yes, 2021
Analyzing tree structural features and capturing their temporal dynamic is challenging but crucial for determining key state variables related to plant function, management practices, and aboveground vegetation stocks.

Systematic Approach for Tunnel Deformation Monitoring with Terrestrial Laser Scanning

open access: yesRemote Sensing, 2021
The use of terrestrial laser scanning (TLS) point clouds for tunnel deformation measurement has elicited much interest. However, general methods of point-cloud processing in tunnels are still under investigation, given the high accuracy and efficiency ...

Individual tree extraction from terrestrial laser scanning data via graph pathing

open access: yesForest Ecosystems, 2021
Individual tree extraction from terrestrial laser scanning (TLS) data is a prerequisite for tree-scale estimations of forest biophysical properties. This task currently is undertaken through laborious and time-consuming manual assistance and quality ...
