tfg.geometry.transformation.euler.from_rotation_matrix

Converts rotation matrices to Euler angles.

tfg.geometry.transformation.euler.from_rotation_matrix(
    rotation_matrix: type_alias.TensorLike,
    name: str = 'euler_from_rotation_matrix'
) -> tf.Tensor

The rotation matrices are assumed to have been constructed by rotation around the \(x\), then \(y\), and finally the \(z\) axis.

Note:

There is an infinite number of solutions to this problem. There are

Gimbal locks when abs(rotation_matrix(2,0)) == 1, which are not handled.

Note:

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

rotation_matrix A tensor of shape [A1, ..., An, 3, 3], where the last two dimensions represent a rotation matrix.
name A name for this op that defaults to "euler_from_rotation_matrix".

A tensor of shape [A1, ..., An, 3], where the last dimension represents the three Euler angles.

ValueError If the shape of rotation_matrix is not supported.
