Thank you for the reply. Are we talking about Hand to eye calibration here?
You are now mixing up the complete thread with asking several question in a row, it will get a bit confused.
My description was for a fixed camera setup. Don't know if it is officially called hand eye calibration, but can't remember a different or the correct name.
May be the term 'Hand eye calibration' normally is used for calibration with camera mounted on robot flange.
