I want to estimate Extrinsic Params about fisheye, but I cannot find any method or function to resolve it. Is there any way to solve it ?

Thank you for your prompt reply. I looked at fisheye documentation, but I think that there are no function that can estimate only Extrinsic Params (fixed Intrinsic Params and Distortion) in fisheye camera. Is my perception correct ? By the way, I recognize the function solvePnP to estimate only Extrinsic Params in "pinhole" camera. Is there any way to resolve my question ? I look forward to some reply.

What's language are you speaking? Python, C++ Java, etc? Link for OpenCV 4.1.x Extrinsic Params For pinhole Pinhole

I'm speaking Python.
I think there are no functions that can estimate only Extrinsic Params in this documenation fisheye.
I think the function solvePnP in this documentation pinhole can estimate only Extrinsic Params .
Is my perception correct ?
Or did I misunderstand anything?
I want to estimate them about fisheye camera.

Btw, I am using raspberry pi 3/4. Unfortunaley, haven't attempted fisheye yet. I am using picamera.
