cedalion.io.photogrammetry.read_photogrammetry_einstar(fn)

Read optodes and fiducials from photogrammetry pipeline.

This method reads the output file as returned by the photogrammetry pipeline using an einstar device.

Parameters:

fn (str) – The filename of the einstar photogrammetry output file.

Returns:

A tuple containing:

• fiducials (cedalion.LabeledPoints): The fiducials as a cedalion

  LabeledPoints object.

• optodes (cedalion.LabeledPoints): The optodes as a cedalion LabeledPoints

  object.

Return type:

tuple

cedalion.io.photogrammetry.read_einstar(fn)

Returns:

A tuple containing:

• fiducials (OrderedDict): The fiducials as an OrderedDict.

• optodes (OrderedDict): The optodes as an OrderedDict.

Return type:

tuple

cedalion.io.photogrammetry.opt_fid_to_xr(fiducials, optodes)
