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.
