A new self-encoded marker for optical pose estimation has been developed. It was designed to cover a wider range of motion and allows to be combined with cameras with a smaller aperture. In this study, we measured accuracy and precision of this novel self-encoded marker on a precision pan-tilt unit and compared the results against similar measurements performed with a standard checkerboard marker. Comparative evaluations between the new self-encoded marker and the checkerboard marker were also performed in vivo and demonstrated superiority of the new marker approach.
