Undistortion Method:
Reality Capture

The undistorted image is similar to the result of Reality Capture

Reset Optical Center:

If set, the center of the image will match the optical center (In other words, the Camera principal point will be set at (0, 0))

Accept Zero Distortion:

If not set and all camera distortion coefficients are zero, the node will return an error
