Visual servoing for micro mass axis alignment device

This paper describes a new observation system for monitoring the operation of a micro machine, and a controller based on the visual servoing method for controlling a micro machine. The application considered is the splicing of optical fibre ribbons. The proposed observation system has only one CCD camera. However, it can be converted into a stereo vision system by using two mirrors. By using the new controller, systems can be controlled based on visual information on image planes rather than in three dimensional space. Our two proposed methods result in a system that is highly accurate, simple and inexpensive. Experimental results on a prototype system reveal the validity and effectiveness of the observation system and the controller based on the visual servoing method.
