1. A method for generating image calibration data at an electronic device having multiple cameras, the method comprising:

  • capturing a first image of a first scene at a first time using a first camera at the electronic device;

    capturing a second image of a second scene at the first time using a second camera at the electronic device, at least a portion of the first scene overlapping a portion of the second scene;

    generating image calibration data based on the first image and based on the second image, the image calibration data used to align images captured by the first camera with images captured by the second camera;

    detecting a first change in orientation of the first camera or a second change in orientation of the second camera, the first change in orientation detected in response to a temperature change and a detected force applied to the first camera, and the second change detected in response to the temperature change and a detected force applied to the second camera; and

    in response to detecting the first change in orientation or in response to detecting the second change in orientation, regenerating image calibration data at the electronic device based on a third image of a third scene captured by the first camera at a second time and based on a fourth image of a fourth scene captured by the second camera at the second time, at least a portion of the third scene overlapping a portion of the fourth scene, the regenerated image calibration data used to align images captured by the first camera with images captured by the second camera.
