This work has been developed among the researches of a PhD thesis in Civil and Environmental Engineering and Architecture of the University of Udine in cooperation with the GECO Laboratory of the Univ...
COMPARATIVE ANALYSIS OF 3D POINT CLOUDS GENERATED FROM A FREEWARE AND TERRESTRIAL LASER SCANNER
Laser Scanning Close Range Photogrammetry Point clouds Heritage VSfM
2017/8/10
In the recent past, several heritage structures have faced destruction due to both human-made incidents and natural calamities that have caused a great loss to the human race regarding its cultural ac...
CALIBRATION AND STABILITY ANALYSIS OF THE VLP-16 LASER SCANNER
Velodyne Stability Calibration LiDAR
2016/3/25
We report on a calibration and stability analysis of the Velodyne VLP-16 LiDAR scanner. The sensor is evaluated for long-term stability, geometric calibration and the effect of temperature variations....
A FRAMEWORK FOR POSITION UNCERTAINTY OF UNORGANISED THREE-DIMENSIONAL POINT CLOUDS FROM NEAR-MONOSTATIC LASER SCANNERS USING COVARIANCE ANALYSIS
Position uncertainty Three-dimensional Point Cloud Laser Scanning
2015/8/13
Position uncertainty is one of the most important quantities of an unorganised three-dimensional point clouds since it
provides the confidence level of any parametric estimation such as surface...
SUB-PIXEL EDGE LOCALIZATION BASED ON LASER WAVEFORM ANALYSIS
Urban Analysis Laser scanning LIDAR Edge Sub-pixel precision
2015/8/13
Laser range data is of high interest in photogrammetry. However, compared to passive imagery, it usually has a lower image
resolution, making geometry extraction and modeling challenging. A method t...
