.left_jacobian_SE3¶
- pytransform3d.transformations.left_jacobian_SE3(Stheta)[source]¶
Left Jacobian of SE(3).
where is the left Jacobian of SO(3) and is given by Barfoot and Furgale (see reference below).
- Parameters:
- Sthetaarray-like, shape (6,)
Exponential coordinates of transformation: S * theta = (omega_1, omega_2, omega_3, v_1, v_2, v_3) * theta, where S is the screw axis, the first 3 components are related to rotation and the last 3 components are related to translation. Theta is the rotation angle and h * theta the translation.
- Returns:
- Jarray, shape (6, 6)
Jacobian of SE(3).
