Classification: CPC G  H | IPC G  H

Claim 0:
1. A computing system comprising:
a communication interface configured to communicate with: (i) a first camera and (ii) a second camera; and
a control circuit configured to:
perform camera calibration based on a three-dimensional (3D) calibration pattern 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, wherein the camera calibration is performed by
receiving a first set of calibration images via the communication interface from the first camera, wherein the first set of calibration images represent the first set of faces of the polyhedron and represent the first set of 2D calibration patterns disposed respectively on the first set of faces, without representing the additional face of the polyhedron,
receiving 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.
