It is necessary for the control system of large radio telescope to real time measure the cabin's position and pose A method of real time measuring cabin's three dimension coordinates is proposed, which is based on the intersecting camera measuring technology First, the cabin's position and pose are expressed by coordinates of three points on the cabin Then the principle of intersecting camera measuring system and the calibration are introduced The computer vision based real time prositioning system, which is employed in 50m model of large radio telescope FAST, is given Finally the authors discuss the feasibility that this positioning system is applied to FAST engineering
