Abstract: A method and apparatus to automatically calibrate one or more attributes of a gaming system. For instance, the gaming system determines, in response to analysis by a processor of image data via a machine-learning model, an orientation of an affixed (e.g., printed) fiducial marker positioned in a known location on a planar playing surface of a gaming table. The system also transforms, in response to determining the orientation, first geometric data associated with an object on the planar playing surface to isomorphically equivalent second geometric data. The system also digitally illustrates, via an augmented reality overlay of the image data using the isomorphically equivalent second geometric data, a graphical representation of the object positioned relative to the fiducial marker on the planar playing surface.
