Utilizarea scanerului laser terestru în măsurătorile forestiere: cerințe metodologice și precauții necesare la aplicarea în practică [TLS in forest inventories: methodology and precautions]
TLS is also known as ground-based LiDAR which provides the capacity to recreate the 3D vegetation structure with millimeter accuracy. The distance measurement of terrestrial laser scanner Z+F Imager 5010 is based on phase shift measurements which is more accurate than time of flight TLS. The time r...

TLS is also known as ground-based LiDAR which provides the capacity to recreate the 3D vegetation structure with millimeter accuracy. The distance
measurement of terrestrial laser scanner Z+F Imager 5010 is based on phase shift measurements which is more accurate than time of flight TLS. The time required
for a single scan varies according to the resolution needed. In forestry, TLS is used for the detailed structured modelling of plots and individual trees. Terrestrial laser scanning of trees has been seen as the best alternative to indirect and direct (destructive) measurements of volume. TLS technique provides accurate estimates the location, DBH and tree height from point cloud and besides these measurements
can be determined the volume on segments, commercial volume or crown volume.The quality of these metrics depends on the original scan data and their co-registration. We have done TLS measurements in six plots from FundivEurope research project with different slopes, tree density and species composition. The measurements allow us to identify which are advantages and disadvantages of using TLS in forest inventory, but in particular this study draws the attention to the precautions required for an accurate TLS use in biomass estimation. |
