1.**VERY IMPORTANT NOTE**: If you want to re-run the extrinsic parameter calibration over the same intrinsic XML files (e.g., if you move the camera location, but you know the instrinsics are the same), you must manually re-set to `1 0 0 0 0 1 0 0 0 0 1 0` the camera matrix of each XML file that will be used for `--combine_cam0_extrinsics`.
