Classification: CPC G  H | IPC G  H

Claim 13:
14. A non-transitory computer-readable medium having instructions thereon that, when executed by a control circuit of a computing system, causes the control circuit
to receive, via a communication interface of the computing system, a first set of calibration images, wherein the communication interface is configured to communicate with: (i) a first camera and (ii) a second camera,
wherein the first set of calibration images are received from the first camera and are generated when a three-dimensional (3D) calibration pattern is disposed on a platform, wherein the 3D calibration pattern comprises a polyhedron having a plurality of faces that include a first set of faces and an additional face that is not part of the first set of faces and is in contact with the platform, and comprises a first set of 2D calibration patterns disposed on respective faces of the first set of faces of the polyhedron,
wherein the first set of calibration images represent the first set of faces and the first set of 2D calibration patterns disposed respectively on the first set of faces, without capturing the additional face of the polyhedron,
wherein the instructions, when executed by the control circuit, further cause the control circuit to
receive a second set of one or more calibration images via the communication interface from the second camera, wherein the second set of one or more calibration images represent the additional face of the polyhedron; and
determining, based on a first set of coordinates and a second set of coordinates, calibration information for the first camera and the second camera, wherein the second set of coordinates corresponds to at least a set of respective corners of the additional face of the polyhedron.
