Comparing RIEGL RiCOPTER UAV LiDAR Derived Canopy Height and DBH with Terrestrial LiDAR
2017
Sensors
Preserved Fulltext
In this study, we present first results and experiences with the RIEGL RiCOPTER with VUX R -1UAV ALS system and compare it with the well tested RIEGL VZ-400 TLS system. ...
We conclude that RiCOPTER has the potential to perform comparable to TLS for estimating forest canopy height and DBH under the studied forest conditions. ...
As first steps we compared the RiCOPTER with the well tested RIEGL VZ-400 TLS by deriving CHM and estimating DBH. ...

A similar accuracy was obtained when combining stem curves estimated with the under-canopy UAV system and tree heights extracted with an above-canopy flying laser scanning unit. ...
Using the random forest model, we were able to estimate the DBH of individual trees with an RMSE of 10–20%, the tree height with an RMSE of 2–8%, and the stem volume with an RMSE of 20–50%. ...
In September 2017 (leaf-on condition), we used the RiCOPTER system (Riegl GmbH) equipped with a VUX-1UAV LiDAR sensor to collect the corresponding point clouds by flying the RiCOPTER at 50 meters above ...
