A new effective orientation method used by hand eye vision system is proposed. A constant transformation matrix describing the correspondence of the end executor reference frame and robot base reference frame is put forward. Together with the assumption of constant distance from the object to the camera, this method simplifies the 3 D orientation problem to 2 D location problem, greatly reducing the computation process. When the position of end executor has been changed, it can still implement orientation...

A new effective orientation method used by hand eye vision system is proposed. A constant transformation matrix describing the correspondence of the end executor reference frame and robot base reference frame is put forward. Together with the assumption of constant distance from the object to the camera, this method simplifies the 3 D orientation problem to 2 D location problem, greatly reducing the computation process. When the position of end executor has been changed, it can still implement orientation without the need of re calibration. The results show that this new method is highly accurate and reliable.
