xdem.coreg.AffineCoreg#
- class xdem.coreg.AffineCoreg(subsample=1.0, matrix=None, meta=None)[source]#
Generic affine coregistration class.
Builds additional common affine methods on top of the generic Coreg class. Made to be subclassed.
Methods
__init__([subsample, matrix, meta])Instantiate a generic AffineCoreg method.
apply(elev[, bias_vars, resample, ...])Apply the estimated transform to a DEM.
centroid()Get the centroid of the coregistration, if defined.
copy()Return an identical copy of the class.
error(reference_elev, to_be_aligned_elev[, ...])Calculate the error of a coregistration approach.
fit(reference_elev, to_be_aligned_elev[, ...])Estimate the coregistration transform on the given DEMs.
fit_and_apply(reference_elev, to_be_aligned_elev)Estimate and apply the coregistration to a pair of elevation data.
from_matrix(matrix)Instantiate a generic Coreg class from a transformation matrix.
from_translation([x_off, y_off, z_off])Instantiate a generic Coreg class from a X/Y/Z translation.
residuals(reference_elev, to_be_aligned_elev)Calculate the residual offsets (the difference) between two DEMs after applying the transformation.
to_matrix()Convert the transform to a 4x4 transformation matrix.
Attributes
is_affineCheck if the transform be explained by a 3D affine transform.
metaMetadata dictionary of the coregistration.
