Scene's 3D modelling, gesture recognition and motion tracking are fields in rapid and continuous development which have caused growing demand on interactivity in video-game and e-entertainment market....
An Integrated Flexible Self-calibration Approach for 2D Laser Scanning Range Finders Applied to the Hokuyo UTM-30LX-EW
LIDAR laser range finder terrestrial laser scanning error model calibration bundle adjustment variance component estimation
2014/7/30
The paper presents a flexible approach for the geometric calibration of a 2D infrared laser scanning range finder. It does not require spatial object data, thus avoiding the time-consuming determinati...
3D CATENARY CURVE FITTING FOR GEOMETRIC CALIBRATION
3D catenary model least square fitting parameter correlation hanging power cables
2014/6/5
In modern road surveys, hanging power cables are among the most commonly-found geometric features. These cables are catenary curves that are conventionally modelled with three parameters in 2D Cartesi...
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...
Calibration free laser-induced breakdown spectroscopy (LIBS) identification of seawater salinity
laser-induced breakdown spectroscopy (LIBS)
2011/5/3
Laser-induced breakdown spectroscopy (LIBS) has been used as a remote sensing system to analyze seawater samples and to identify their salinities without ordinary calibration curves. The plasma is gen...
