Abstract
Systems and methods are described in the present disclosure for determining the location and orientation of an object placed on a surface. One such system, among others, includes an optical device physically supported by an object at a fixed position with respect to a reference point of the object. The system also includes a surface upon which the object can be placed. A reference pattern, which is applied to the surface, includes an array of markings visible to the optical device. The array of markings includes encoded location information and orientation information. In addition, the system includes a processing device in communication with the optical device. The processing device is configured to calculate the location and orientation of the reference point of the object with respect to the surface.
