tfg.geometry.transformation.rotation_matrix_3d.is_valid

Determines if a matrix is a valid rotation matrix.

tfg.geometry.transformation.rotation_matrix_3d.is_valid(
    matrix,
    atol=0.001,
    name=None
)

Defined in geometry/transformation/rotation_matrix_3d.py.

Note:

In the following, A1 to An are optional batch dimensions.

Args:

  • matrix: A tensor of shape [A1, ..., An, 3,3], where the last two dimensions represent a matrix.
  • atol: Absolute tolerance parameter.
  • name: A name for this op that defaults to "rotation_matrix_3d_is_valid".

Returns:

A tensor of type bool and shape [A1, ..., An, 1] where False indicates that the input is not a valid rotation matrix.
