Dynamic depth camera system calibration using mobile dispay device

A depth camera calibration system comprising:

• a depth camera to be calibrated;
• a projection application to execute upon a mobile device having a display screen, the projection application to
• (i) determine a size of an image of a geometric target to be displayed upon the display screen, wherein the size of the image of the geometric target is determined based at least in part on a size and screen resolution of a the display screen of the mobile device when the geometric target is displayed upon the screen of the mobile device,
• (ii) encode the determined size of the image of the geometric target into an optical machine-readable data representation, the optical machine-readable data representation comprising one of a Quick Response (QR) code, a barcode, or a two-dimensional matrix barcode,
• (iii) cause display, to the display screen, of the optical machine-readable data representation having the determined size of the image of the geometric target encoded therein, and
• (iv) cause display, to the display screen, of the image of the geometric target;
• and
• wherein the depth camera is to
• (i) read the optical machine-readable data representation displayed by the mobile device to determine the size of the image of the geometric target encoded into the optical machine-readable data representation, and
• (ii) capture the displayed image of the geometric target and apply an optimization process to calibrate the depth camera based on the encoded determined size of the image of the geometric target as displayed by the mobile device.

A non-transitory machine-readable medium encoded with instructions that when executed by one or more processors cause a process to be carried out for performing mobile device based dynamic depth camera calibration, the process comprising:

• determine a size of an image of a geometric target to be displayed upon a display screen of a mobile device, wherein the size of the image of the geometric target is determined based at least in part on a size and screen resolution of the display screen;
• encode the determined size of the image of the geometric target into an optical machine-readable data representation, the optical machine-readable data representation comprising one of a Quick Response (QR) code, a barcode, or a two-dimensional matrix barcode;
• cause display, to the display screen, of the optical machine-readable data representation, so that a depth camera system can read the optical machine-readable data representation to determine the size of the image of the geometric target encoded into the optical machine-readable data representation;
• and
• cause display, to the display screen, of the image of the geometric target, so the depth camera system can capture the displayed image of the geometric target and apply an optimization process to calibrate the depth camera system based on the encoded determined size of the image of the geometric target as displayed by the mobile device.
