In this paper, we propose a calibration-free three dimensional position measurement system based on active vision. In this system, two pan-tilt cameras are controlled so that the target is located at the center of the images. Then three dimensional coordinates of the target position are calculated using a triangulation method. To extend the proposed method to measurement of moving objects, a tracking control using motion estimation is introduced. The result is veriļ¬ed via numerical simulations and experiment.
