weldx.transformations.LocalCoordinateSystem.from_homogeneous_transformation#
- classmethod LocalCoordinateSystem.from_homogeneous_transformation(transformation_matrix, translation_unit, time=None, time_ref=None)#
Construct a local coordinate system from a homogeneous transformation matrix.
- Parameters:
transformation_matrix (
Union[DataArray,ndarray]) – Describes the homogeneous transformation matrix that includes the rotation and the translation (coordinates).translation_unit (
Union[str,Unit,UnitsContainer]) – Unit describing the value of the translation. Necessary, because the homogeneous transformation matrix is unitless.time (
Union[DatetimeIndex,datetime64,list[str],Time,TimedeltaIndex,Quantity,timedelta64,Timestamp,str,TimeDependent,None]) – Time data for time dependent coordinate systems (Default value = None)time_ref (
Union[Timestamp,str,Time,None]) – Optional reference timestamp iftimeis a time delta.
- Returns:
Local coordinate system
- Return type:
