Surface Reconstruction via Total Least-Squares Adjustment of the Semi-Variogram
Surface reconstruction Kriging Semi-variogram TLS
2015/12/8
One well established technique to construct a surface that best fits to an observed scattered point cloud is based on the Kriging methodology that uses semi-variograms. It somewhat resembles least-squ...
Performing Space Resection Using Total Least Squares
total least squares space resection exterior orientation elements least squares
2015/12/8
In space resection computing，the error equations are based on the collinearity equations. Because the coordinates of the ground point and the image point all exist errors. So we use the Total Least Sq...
