Abstract
A linear method that calibrates a camera from a single view of two concentric semicircles of known radii is presented. Using the estimated centers of the projected semicircles and the four corner points on the projected semicircles, the focal length and the pose of the camera are accurately estimated in real-time. Our method is applied to augmented reality applications and its validity is verified.
