Selecting camera to present image for calibration
A method of calibrating multiple cameras includes determining a first position of an overlay within a first field of view of a first camera and a second position of the overlay within a second field of view of a second camera; selecting, from the first camera and the second camera based on the first position and the second position, the first camera as a presentation camera; presenting, on a display, an image of a calibration object captured by the presentation camera and the overlay, the overlay indicating a calibration position for the calibration object with respect to the presentation camera; capturing a first calibration image of the calibration object by the first camera and a second calibration image of the calibration object by the second camera; and calibrating the first camera based on the first calibration image and calibrating the second camera based on the second calibration image.

6 . The method of claim 1 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on a distance between the first camera and the overlay being greater than a distance between the second camera and the overlay.
7 . The method of claim 1 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on the first camera having been previously selected as the presentation camera.
8 . The method of claim 1 , wherein the first camera is coupled to the display and the second camera is coupled to the display.

determine a first position of an overlay within a first field of view of a first camera and a second position of the overlay within a second field of view of a second camera, the overlay indicating a calibration position for a calibration object, the first camera and the second camera being included in the computing device;
select, from the first camera and the second camera based on the first position and the second position, the first camera as a presentation camera;
present, on a display, an image of the calibration object captured by the presentation camera and the overlay, the overlay indicating the calibration position to guide a user in placing the calibration object with respect to the presentation camera;
capture a first calibration image of the calibration object by the first camera and a second calibration image of the calibration object by the second camera; and
calibrate the first camera based on the first calibration image and calibrate the second camera based on the second calibration image.
10 . The non-transitory computer-readable storage medium of claim 9 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on a predetermined portion of the overlay being within the first field of view.
11 . The non-transitory computer-readable storage medium of claim 9 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on a predetermined portion of the overlay being closer to a center of the first field of view than the predetermined portion of the overlay is to a center of the second field of view.
12 . The non-transitory computer-readable storage medium of claim 9 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on a number of corners of the overlay included in the first field of view being greater than a number of corners of the overlay included in the second field of view.
13 . The non-transitory computer-readable storage medium of claim 9 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on an angle between a plane extending through the overlay and a line between the first camera and the overlay being closer to perpendicular than an angle between the plane extending through the overlay and a line between the second camera and the overlay.
14 . The non-transitory computer-readable storage medium of claim 9 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on a distance between the first camera and the overlay being greater than a distance between the second camera and the overlay.
15 . The non-transitory computer-readable storage medium of claim 9 , wherein the selecting the first camera includes selecting the first camera as the presentation camera based on the first camera having been previously selected as the presentation camera.
16 . The non-transitory computer-readable storage medium of claim 9 , wherein the first camera is coupled to the display and the second camera is coupled to the display.
17 . A computing device comprising:
at least one processor; and
