Its computation and updating require screw vector. The relative pose information need to be updated when measuring the pose of the rigid body. In the traditional algorithm, it generally focuses on attitude updating, but less research on position updating. The rotation vector algorithm is used to represent the quaternion to update the attitude of the rigid body, but it cannot update the position. Because any general rigid body motion can be realized by rotation about a certain axis and translation along this axis, this article proposes an algorithm to update the position and attitude of the rigid body’s relative motion based on the screw vector.
