UAV-derived counts of waterfowl were greater (+37%) than ground counts. The results indicated the feasibility and advantages of using a low-cost UAV ... W Ding,L Su,Yuanman_Hu,... - 《Drones》 被引量: 0发表: 2021年 加载更多站...
The results suggest that at plot level, UAV(SfM)-generated point clouds are as good as ALS-derived point clouds for estimating individual tree height. Furthermore, analysis of the differences in digital elevation models at landscape level showed that the elevations of the UAV(SfM)-derived ...
In addition, to evaluate the biomass predicted from UAV-derived canopy features, biomass-GMP and biomass-YSI computed using the predicted biomass (i.e., all the canopy features were used as predictors) were compared with those computed using ground truth biomass.(14)BiomassGMP=(BiomassWW×Biomass...
We used a very high resolution digital elevation model (2.5 cm horizontal, 2.2 cm vertical resolution) derived from an UAV based Structure from Motion photogrammetry to map hollows and hummocks in the peatland area. We also created a 2 cm spatial resolution orthophoto mosaic to enhance the ...
From our results, it can be concluded that ITD can be performed with an acceptable accuracy (F > 0.80) from UAV-derived CHMs in an open canopy forest, and has the potential to supplement future research directed towards estimation of above ground biomass and stem volume from UAV-imagery.View...
In this study, we compare the topography of UAV-derived DEMs, three open-access global DEM products, and the 8 m High Mountain Asia (HMA) DEMs (released in December 2017) and assess their suitability for landslide- and flood-related hazard assessments. We observed close similarity between UAV...
Afterwards, the UAV-derived point cloud was normalized to height above ground by subtraction of the DTM elevation from the Z coordinate of each point projected on the ground using the ClipData tool. CanopyModel function, also in FUSION/LDV, was used to compute the CHM with 0.5 m of spatial...
The random forest (RF) algorithm was used to estimate the garlic yield by comparing two different training feature sets: the vegetation indices (VIs) and the VIs with the addition of the texture features extracted from the UAV images. The most important VIs were selected using the recursive ...
AVIATOR is a UAV-RC data traffic generation tool based on the data distribution models derived from our experimental UAV measurements. It generates UDP packets according to the data rate, inter-packet interval and packet length distributions of commercial UAV-RC traffic (DJI Spark, DJI Mavic Air ...
