Member Function Documentation

vpHomogeneousMatrix vpUnicycle::get_cMe ( ) const
inline

Return the tranformation ${^c}{\bf M}_e$ between the camera frame and the mobile robot end effector frame.

Definition at line 78 of file vpUnicycle.h.

vpVelocityTwistMatrix vpUnicycle::get_cVe ( ) const
inline

Return the twist transformation from camera frame to the mobile robot end effector frame. This transformation allows to compute a velocity expressed in the end effector frame into the camera frame.

Examples:
servoPioneerPanSegment3D.cpp, servoPioneerPoint2DDepth.cpp, servoPioneerPoint2DDepthWithoutVpServo.cpp, tutorial-simu-pioneer-pan.cpp, and tutorial-simu-pioneer.cpp.

void vpUnicycle::get_cVe ( vpVelocityTwistMatrix &  cVe) const
inline

Return the twist transformation from camera frame to the mobile robot end effector frame. This transformation allows to compute a velocity expressed in the end effector frame into the camera frame.

vpMatrix vpUnicycle::get_eJe ( ) const
inline

Return the robot jacobian ${^e}{\bf J}_e$ expressed in the end effector frame.

Returns
The robot jacobian such as ${\bf v} = {^e}{\bf J}_e \; \dot{\bf q}$ with $\dot{\bf q} = (v_x, w_z)$ the robot control velocities and $\bf v$ the six dimention velocity skew.
Examples:
servoPioneerPanSegment3D.cpp.

void vpUnicycle::set_cMe ( const vpHomogeneousMatrix &  cMe)
inline

Set the transformation between the camera frame and the end effector frame.

void vpUnicycle::set_eJe ( const vpMatrix &  eJe)
inline

Set the robot jacobian ${^e}{\bf J}_e$ expressed in the end effector frame.

Parameters
eJe: The robot jacobian to set such as ${\bf v} = {^e}{\bf J}_e \; \dot{\bf q}$ with $\dot{\bf q} = (v_x, w_z)$ the robot control velocities and $\bf v$ the six dimention velocity skew.
