pose_to_dual_quat T_pose_to_dual_quat PoseToDualQuat PoseToDualQuat pose_to_dual_quat (Operator)
Name
pose_to_dual_quat T_pose_to_dual_quat PoseToDualQuat PoseToDualQuat pose_to_dual_quat
— Convert a 3D pose to a unit dual quaternion.
Signature
def pose_to_dual_quat (pose : Sequence[Union[float, int]]) -> Sequence[float]
Description
The operator pose_to_dual_quat pose_to_dual_quat PoseToDualQuat PoseToDualQuat PoseToDualQuat pose_to_dual_quat
converts the input Pose Pose Pose Pose pose pose
into its corresponding unit dual quaternion DualQuaternion DualQuaternion DualQuaternion DualQuaternion dualQuaternion dual_quaternion
.
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”
.
Because
and
represent the same rigid
transformation, the sign of the resulting dual quaternion
DualQuaternion DualQuaternion DualQuaternion DualQuaternion dualQuaternion dual_quaternion
is chosen such that the scalar part of the real
part is
.
Multiple poses can be passed in Pose Pose Pose Pose pose pose
, in which case a unit dual
quaternion is returned for each of them.
Execution Information
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.
