<p>A method of determining the prospective location of two or more fiducial markers includes the steps of: with respect to the work piece, defining a path having a radius from an origin which varies in a non-repetitive manner with respect to the angular displacement of the path from the origin; and selecting two or more prospective locations of respective fiducial markers. The prospective locations are positioned relative to the work piece substantially at points along the defined path.</p> |
