描述

算子 dual_quat_composedual_quat_composeDualQuatComposeDualQuatComposeDualQuatComposedual_quat_compose multiplies the two dual quaternions DualQuaternionLeftDualQuaternionLeftDualQuaternionLeftDualQuaternionLeftdualQuaternionLeftdual_quaternion_left and DualQuaternionRightDualQuaternionRightDualQuaternionRightDualQuaternionRightdualQuaternionRightdual_quaternion_right and returns the product in DualQuaternionComposedDualQuaternionComposedDualQuaternionComposedDualQuaternionComposeddualQuaternionComposeddual_quaternion_composed。

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 multiplication of the dual quaternions and is 。

For the multiplication of quaternions see quat_composequat_composeQuatComposeQuatComposeQuatComposequat_compose。

Note that the multiplication of two dual quaternions is not commutative, i.e., 。

If DualQuaternionLeftDualQuaternionLeftDualQuaternionLeftDualQuaternionLeftdualQuaternionLeftdual_quaternion_left and DualQuaternionRightDualQuaternionRightDualQuaternionRightDualQuaternionRightdualQuaternionRightdual_quaternion_right are unit dual quaternions and, hence, represent 3D rigid transformations, their multiplication corresponds to the multiplication of their corresponding homogeneous transformation matrices. Consequently, dual_quat_composedual_quat_composeDualQuatComposeDualQuatComposeDualQuatComposedual_quat_compose can be used to concatenate two 3D rigid transformations analogously to pose_composepose_composePoseComposePoseComposePoseComposepose_compose or hom_mat3d_composehom_mat3d_composeHomMat3dComposeHomMat3dComposeHomMat3dComposehom_mat3d_compose。
