Abstract
A method of determining a relative location of a first pattern and a second pattern includes providing a fiducial including a fiducial origin, a first camera, a second camera, and an image registration controller. A first fiducial image of the fiducial origin is captured using the first camera. A second fiducial image of the fiducial origin is captured using the second camera. A first pattern image of a first pattern is captured using the first camera. A second pattern image of a second pattern is captured using the second camera. A first location of the first pattern relative to the fiducial origin is determined using the image registration controller. A second location of the second pattern relative to the fiducial origin is determined using the image registration controller. A relative location of the first location and the second location is determined using the image registration controller.
