Abstract: A new fiducial marker for augmented reality was designed along with a method that recognizes the markers captured by a camera and calculates the relative position and orientation between the markers and the camera. These markers can be used at both long and short distances without increasing their number in the environment. Results of the experimental evaluation show that the new marker can be used in a larger area than legacy markers such as square markers and circular markers.
