I have a CCD camera pair on the end of a robot arm which (quiet successfully)
guides the robot arm to intercept an object in the workcell. To determine the
relationship between the world and the robot coordinate system I carry out
camera-to-world calibration and toolpoint-to-eye calibration.
Not only are these calibrations tedious and complex but they are also error-prone.

My question to the newsgroup is: what are the alternatives ?
