Robust Algorithm for Fitting Sphere to 3D Point Clouds in Terrestrial Laser Scanning
Laser scanning Fitting Terrestrial photogrammetry
font style='font-size:12px;'>
2015/12/16
Sphere target is one of the most important tools in terrestrial laser scanning. Different point clouds obtained form different views can
be transformed into the same coordinate system frame by using ...
REPRESENTATION OF GRADIENTS OF A SCALAR FIELD ON THE SPHERE USING A 2D FOURIER EXPRESSION
2D Fourier series gradients representation coefficients D-functions spectral transfers
