Abstract
The three-dimensional orientation of a given object is determined. The given object may comprise an object having surface characteristics which provide poor contrast in representative images of the given object. In a specific embodiment, the object may comprise a golf ball. A model representation is obtained of a reference object, and a run-time image is obtained of the given object. From the run-time image, shape information is obtained for certain identified shapes collectively forming a subset of the visible shapes. The shape information is matched to a number of incremental poses of the model representation varying along three degrees of freedom.
