A method to estimate the relative position and orientation of a camera to a circle having unknown radius is presented. A possible application of this problem is the automatic landing of a helicopter because the method can replace human pilots who estimate their position and orientation relative to the landing site by observing the circle marked in heliports. The method is formulated on the framework of the recursive estimation using an image sequence of a circle. The results of the experiment both on the synthetic data and the real image show the proposed method works adequately.
