Module Contents

opticam.utils.transforms.find_translation(reference_coords, coords)

Find the translation that maps reference_coords onto coords. An advantage of this over astroalign.find_transform() is that it requires fewer sources, however it is therefore more prone to errors. In general, astroalign.find_transform() should be used, but find_translation() is available if there are too few sources for astroalign.find_transform().

Parameters

reference_coordsNDArray

The reference source coordinates.

coordsNDArray

The source coordinates.

Returns

SimilarityTransform

The transformation matrix that maps coords onto reference_coords.

Parameters:

• reference_coords (numpy.typing.NDArray)

• coords (numpy.typing.NDArray)

Return type:

skimage.transform.SimilarityTransform
