Name
dual_quat_to_hom_mat3d T_dual_quat_to_hom_mat3d DualQuatToHomMat3d DualQuatToHomMat3d dual_quat_to_hom_mat3d
— Convert a unit dual quaternion into a homogeneous transformation matrix.
Signature
def dual_quat_to_hom_mat3d (dual_quaternion : Sequence[float]) -> Sequence[float]
Description
The operator dual_quat_to_hom_mat3d dual_quat_to_hom_mat3d DualQuatToHomMat3d DualQuatToHomMat3d DualQuatToHomMat3d dual_quat_to_hom_mat3d
converts a unit dual quaternion
DualQuaternion DualQuaternion DualQuaternion DualQuaternion dualQuaternion dual_quaternion
, which represents a 3D rigid transformation,
into its corresponding homogeneous transformation matrix HomMat3D HomMat3D HomMat3D HomMat3D homMat3D hom_mat_3d
.
For a brief introduction to dual quaternions, the used notation, and the
relationship between dual quaternions and screws, see
“Solution Guide III-C - 3D Vision”
.
The rotation part of HomMat3D HomMat3D HomMat3D HomMat3D homMat3D hom_mat_3d
is computed from the
real part of the dual quaternion, as described in quat_to_hom_mat3d quat_to_hom_mat3d QuatToHomMat3d QuatToHomMat3d QuatToHomMat3d quat_to_hom_mat3d
.
The translation part
of HomMat3D HomMat3D HomMat3D HomMat3D homMat3D hom_mat_3d
is computed
from the real and dual part of
:
where
is the vector part of the quaternion
.
Attention
HomMat3D HomMat3D HomMat3D HomMat3D homMat3D hom_mat_3d
will only be a valid rigid transformation matrix if
DualQuaternion DualQuaternion DualQuaternion DualQuaternion dualQuaternion dual_quaternion
is a unit dual quaternion.
