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...
Airborne Laser Scanning and Image Processing Techniques for Archaeological Prospection
Digital terrain model non-invasive archaeology DTM shaded relief LiDAR
2014/7/30
Aerial photography was, for decades, an invaluable tool for archaeological prospection, in spite of the limitation of this method to deforested areas. The airborne laser scanning (ALS) method can be n...
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...
APPLYING 3D AFFINE TRANSFORMATION AND LEAST SQUARES MATCHING FOR AIRBORNE LASER SCANNING STRIPS ADJUSTMENT WITHOUT GNSS/IMU TRAJECTORY DATA
Airborne Laser Scanning adjustment LIDAR georeferencing quality control
2014/6/5
In this article we extend our previous work on the topic of ALS strip adjustment without GNSS/IMU trajectory data. Between overlap- ping strip pairs the relative orientation as a 3D affine trans...
CLASSIFICATION OF AIRBORNE LASER SCANNING DATA IN WADDEN SEA AREAS USING CONDITIONAL RANDOM FIELDS
