JOINT CALIBRATION OF 3D LASER SCANNER AND DIGITAL CAMERA BASED ON DLT ALGORITHM
Direct Linear Transformation 3D laser scanner Digital camera Point-cloud Image
2018/5/14
Design a calibration target that can be scanned by 3D laser scanner while shot by digital camera, achieving point cloud and photos of a same target. A method to joint calibrate 3D laser scanner and di...
AUTOMATED CALIBRATION OF FEM MODELS USING LIDAR POINT CLOUDS
Point clouds LiDAR rasterization FEM analysis bending moment torque
2018/6/5
In present work it is pretended to estimate elastic parameters of beams through the combined use of precision geomatic techniques (laser scanning) and structural behaviour simulation tools. The study ...

LIDAR Calibration Targets Quality Radiometric Calibration field Laser scanning
2015/9/1
In this paper the calibration of Optech ALTM 3100 laser scanner intensity is reported using airborne experiments and known brightness targets. The Finnish Geodetic Institute has had a permanent photog...
POINT-BASED VERSUS PLANE-BASED SELF-CALIBRATION OF STATIC TERRESTRIAL LASER SCANNERS
Terrestrial Laser scanning LIDAR Calibration Modelling Precision Point Cloud Analysis
2014/6/5
Systematic trends are apparent when studying the self-calibration residuals of many modern static terrestrial laser scanners. Since the operation of terrestrial laser scanners is comparable to an effi...
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...
We show that a fiber polarimeter can be calibrated in place at a distance of 30km even when the intervening fiber varies in temperature. The calibration accuracy converges after at most 20 random stok...
