MEASURING A DYNAMIC AND FLOODING RIVER SURFACE BY CLOSE RANGE DIGITAL PHOTOGRAMMETRY
Close Range Photogrammetry Digital Surface Models Digital Photogrammetry Feature Extraction Hydrology, Floods Point Cloud
2015/12/26
Current state of the art computational fluid dynamics (CFD) and in particular, river flow modelling, require accurate estimation of the “free surface” in order to accurately predict the three dimensio...
FROM POINT CLOUD TO SURFACE:MODELING STRUCTURES IN LASER SCANNER POINT CLOUDS
Laserscanning Photogrammetry Feature Extraction Segmentation Modeling Software Development
2015/11/10
The automatic modeling of precise structures from randomly distributed laser points derived from laser scanner data is a very hard problem, not completely solved and problematic in case of incomplete,...
LEAF AREA INDEX ESTIMATION IN VINEYARDS FROM UAV HYPERSPECTRAL DATA,2D IMAGE MOSAICS AND 3D CANOPY SURFACE MODELS
Precision agriculture biomass crop narrow band indices
2015/9/10
The indirect estimation of leaf area index (LAI) in large spatial scales is crucial for several environmental and agricultural applications. To this end, in this paper, we compare and evaluate LAI est...
