1. A method comprising:
receiving, at a processing unit, a first frame from a first camera and a second frame from a second camera, wherein the first camera provides first time data for when the first frame is captured by the first camera and the second camera provides second time data indicating when the second frame is captured by the second camera;
associating, with the first image and independent of the first time data, a first timestamp;
associating, with the second image and independent of the second time data, a second timestamp;
determining, by the processing unit, whether the first camera and the second camera are synchronized based on the first timestamp and the second timestamp;
selecting, responsive to the first camera and the second camera being desynchronized, a camera from the first camera and the second camera; and
resynchronizing the first camera and the second camera by transmitting a padding data instruction to the selected camera.
