COMPARISON WITH ACCURACY OF TERRESTRIAL LASER SCANNER BY USING POINT CLOUD ALIGNED WITH SHAPE MATCHING AND BEST FITTING METHODS
laser scanning time of flight phase shift shape matching natural distributions Ostia
2019/3/4
Recently operation systems of laser scanning have been obviously improved; for instance shape matching has been equipped with software on a post processing stage so measurement without any targets is ...
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...
Spectral Reflectance Characteristics of Different Snow and Snow-Covered Land Surface Objects and Mixed Spectrum Fitting
Snow Snow-covered land surface object Spectral characteristics Spectral fitting
2012/4/17
The field spectroradiometer was used to measure spectra of different snow and snow-covered land surface objects in Beijing area. The result showed that for a pure snow spectrum, the snow reflectance p...
