Three-View Uncalibrated Visual Servoing
Full Text: shademan2010c.pdfWe describe a new uncalibrated visual servoing approach for motion control of 6-DOF manipulators. Instead of image features, we use the elements of the scene-independent trifocal tensor of three views as features. The trifocal features depend only on the camera projection matrices and can be retrieved from point correspondences across the three views: initial, current, and desired. The Jacobian matrix that relates joint velocities and variations of the trifocal features is estimated online using least-squares. We evaluate the visual servoing performance for various easy and challenging motions, such as the translational motion along the view axis and the large rotation around the view axis. Simulations with a 6-DOF eye-in-hand manipulator show that the proposed method rapidly converges in all cases.
