The virtue of feedback control is that it can be used to make a controlled process accomplish a prescribed task, despite noise and process, sensor, and actuator modeling errors.
Vision systems admit imprecise models because they are difficult to calibrate.
Thus, within the context of robot positioning tasks, it is natural to ask if one can precisely accomplish a given task, when imprecisely modeled cameras are used as feedback sensors. The pose of the robot and the target are each determined by a list of point features simultaneously observed by an imprecisely modeled stereo vision system.
