3D BUILDING MODEL GENERATION FROM AIRBORNE LASER SCANNER DATA USING 2D GIS DATA AND ORTHOGONAL POINT CLOUD PROJECTIONS
LIDAR point cloud segmentation building model reconstruction automation
2015/8/13
Human operators use an intuitive procedure of rotating laser scanner point clouds into specific projections when trying to understand
the structure of buildings contained in the data. This procedure ...
FILTERING OF AIRBORNE LASER SCANNER DATA BASED ON SEGMENTED POINT CLOUDS
Segmentation Filtering Laser scanning LiDAR
2015/8/13
The extraction of points on the bare Earth from point clouds acquired by airborne laser scanning is the most time consuming and
expensive part in the production of digital elevation models with laser...
A voxel-based technique to estimate the volume of trees from terrestrial laser scanner data
Terrestrial Laser Scanning Point Cloud Tree Volume Estimation Voxel
2014/7/30
The precise determination of the volume of standing trees is very important for ecological and economical considerations in forestry. If terrestrial laser scanner data are available, a simple approach...
DETECTION OF COLLAPSED BUILDINGS BY CLASSIFYING SEGMENTED AIRBORNE LASER SCANNER DATA
Supervised classification maximum entropy modelling rule based classification airborne laser scanner data segmentation object-based point cloud analysis
2014/6/5
Rapid mapping of damaged regions and individual buildings is essential for efficient crisis management. Airborne laser scanner (ALS) data is potentially able to deliver accurate information on the 3D ...
VOXEL-BASED ESTIMATION OF PLANT AREA DENSITY FROM AIRBORNE LASER SCANNER DATA
Canopy structure Three-dimensional (3-D) Flight line Lidar Plant area index Crown volume
2014/6/5
Three-dimensional distribution of plant area density (PAD) was retrieved using airborne laser scanning (ALS) data. The calculation of PAD requires the number of laser-pulses intercepted by plant mater...
APPROXIMATION OF VOLUME AND BRANCH SIZE DISTRIBUTION OF TREES FROM LASER SCANNER DATA
LIDAR point cloud trees classification size approximation carbon cycle
2014/6/5
This paper presents an approach for automatically approximating the above-ground volume and branch size distribution of trees from dense terrestrial laser scanner produced point clouds. The approach i...
LASER PULSE VARIATIONS AND THEIR INFLUENCE ON RADIOMETRIC CALIBRATION OF FULL-WAVEFORM LASER SCANNER DATA
Radiometric Calibration Full-Waveform Laser Scanning Error Assessment
2014/6/5
Full-waveform laser scanning extends the information content of "conventional" laser scanning by storing the temporal profile of both the emitted laser pulse and its echoes. This allows for calc...
