By exploiting the projective properties of a circular set of sizeable dots, we propose a detection algorithm that is highly accurate. Applying a dot pattern scheme derived from error-correcting codes, allows for robustness with respect to very large occlusions. In addition, the design of the marker itself
is flexible enough to accommodate different requirements in terms of pose accuracy and number of patterns.
