  • Method for determining the location and orientation of a fiducial reference
    Patent number: 9918657
    Abstract: A method for determining the 3D location and orientation of a fiducial reference comprises disposing the fiducial reference so as to render a part of the fiducial reference observable by a tracker; obtaining from the tracker scan data of the part of the fiducial reference that is observable by the tracker; obtaining predetermined geometric information about location points on the fiducial reference, the geometric information containing three-dimensional coordinates of the location points relative to the structure of the fiducial reference; identifying within the scan data at least three location points having coordinates in the predetermined geometric information; and determining from the scan data and the coordinates of the three identified location points in the predetermined geometric information the 3D location and orientation of the fiducial reference.
