System and methods to calibrate mobile device camera
A system to calibrate a camera of a mobile device includes a fixture configured to hold the mobile device with the camera and a display of the mobile device exposed to an outside of the fixture; and a moving mechanism to move the fixture.
1. A system to calibrate a camera of a mobile device, the system comprising:
a fixture configured to hold the mobile device;
wherein the fixture consisting of a ‘U’ shaped bracket having an opening and sidewalls forming an interior volume and a support secured to the lower side of the fixture; and wherein
the camera and a display of the mobile device exposed to an outside of the fixture;
a moving mechanism is operably coupled to the support to move the fixture; and
a computer interfaced to the mobile device and including a camera calibration software application that controls gathering data and saving camera performance parameters to the mobile device.
2. The system of claim 1 , wherein the camera calibration software application supports calibration of more than one mobile device cameras simultaneously.
3. The system of claim 1 , wherein the fixture is a plurality of fixtures.
4. The system of claim 3 , wherein all of the plurality of fixtures are moved at substantially a same speed with a same movement.
5. The system of claim 1 , wherein the sidewalls of the fixture includes a clear window configured to view a display of the mobile device.
6. The system of claim 1 , wherein the moving mechanism is configured to move the fixture by rotating the fixture alternating in a first horizontal direction and in a second horizontal direction that is opposite to the first horizontal direction.
7. The system of claim 1 , wherein the moving mechanism includes a microcontroller programmed to operate a motor and a belt attached to the motor and the fixture.
8. The system of claim 1 , wherein the camera calibration software provides a notice that calibration is complete.
9. The system of claim 8 , wherein the notice is a visible or audible alert.
10. The system of claim 1 , wherein a depth function of the mobile device is calibrated.
11. The system of claim 1 , wherein the support secures the fixture to a calibration jig, wherein the calibration jig holds the movement mechanism and the fixture.
12. A method of calibrating a camera of a mobile device comprising:
putting the mobile device into a camera calibration mode;
interfacing the mobile device to a computer running a camera calibration software application that controls gathering data and saving camera performance parameters to the mobile device;
placing the mobile device into a fixture;
moving the fixture; and
saving a camera calibration configuration to the mobile device.
13. The method of claim 12 , wherein the fixture is rotated horizontally.
14. The method of claim 12 , wherein the fixture is rotated plus and minus about 35 degrees.
15. The method of claim 12 , wherein the camera calibration software application supports calibration of more than one mobile device cameras simultaneously.
16. The method of claim 12 , wherein the fixture is a plurality of fixtures, and
all of the plurality of fixtures are moved at substantially a same speed with a same movement.
17. The method of claim 12 , wherein the camera calibration configuration includes a depth function.
18. A system to calibrate a camera of a mobile device, the system Consisting of:
a fixture configured to hold the mobile device;
wherein the fixture consisting of a ‘U’ shaped bracket having an opening and sidewalls forming an interior volume and a support secured to the lower side of the fixture; and wherein
the camera and a display of the mobile device exposed to an outside of the fixture;
a moving mechanism is operably coupled to the support to move the fixture;
wherein the moving mechanism is configured to move the fixture by rotating the fixture alternating in a first horizontal direction and in a second horizontal direction that is opposite to the first horizontal direction; and
a computer interfaced to the mobile device and including a camera calibration software application that controls gathering data and saving camera performance parameters to the mobile device.
