Thanks, Paul and Michael, your answers help me a lot.
To Michael, you are correct. I have a normal fisheye mounted to the ceiling.
ih_fov and iv_fov must be 180 degrees. Your command worked perfectly.
To Paul, at first, I have a little confused between the specification along
with the camera and
Never mind. I figured it out based on the sizes of the 'exe' files.

Generally, neither your cpu nor your gpu matter,
