Classification: CPC G  H | IPC G  H

Claim 3:
4. The computing system of claim 2, wherein the control circuit is configured, when performing the camera calibration:
to determine, based on the second calibration image of the at least one pair of calibration images, a set of pixel regions in which respective corners of the additional 2D calibration pattern appear in the second calibration image; and
to search the first calibration image of the at least one pair of calibration images, also within the set of pixel regions, to identify pixel coordinates at which the set of respective corners of the additional face appear in the first calibration image,
wherein the second set of coordinates for the set of respective corners are determined based on the pixel coordinates at which the set of respective corners appear in the first calibration image.
