Robotic Eye-in-hand Calibration in an Uncalibrated Environment
Sebastian van Delden, Frank Hardy · DOAJ (DOAJ: Directory of Open Access Journals) · 2008
The optical flow of high interest points in images of an uncalibrated scene is used to recover the camera orientation of an eye-in-hand robotic manipulator. The system is completely automated, iteratively performing a sequence of rotations and translations until the camera frame is aligned with the manipulator's world frame. The manipulator must be able to translate and rotate its end-effector with respect to its world frame. The system is implemented and being tested on a Stäubli RX60 manipulator using an off-the-shelf Logitech USB camera.
