xdem.coreg.AffineCoreg#

class xdem.coreg.AffineCoreg(meta=None, matrix=None)[source]#

Generic affine coregistration class.

Builds additional common affine methods on top of the generic Coreg class. Made to be subclassed.

__init__(meta=None, matrix=None)[source]#

Instantiate a generic Coreg method.

Methods

__init__([meta, matrix])

Instantiate a generic Coreg method.

apply(dem[, transform, crs, resample])

Apply the estimated transform to a DEM.

apply_pts(coords)

Apply the estimated transform to a set of 3D points.

centroid()

Get the centroid of the coregistration, if defined.

copy()

Return an identical copy of the class.

error(reference_dem, dem_to_be_aligned[, ...])

Calculate the error of a coregistration approach.

fit(reference_dem, dem_to_be_aligned[, ...])

Estimate the coregistration transform on the given DEMs.

fit_pts(reference_dem, dem_to_be_aligned[, ...])

Estimate the coregistration transform between a DEM and a reference point 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_dem, dem_to_be_aligned)

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_affine

Check if the transform be explained by a 3D affine transform.
