Is it possible to do cylinder surface fitting?

Hi, thanks for your plane fitting code several years ago. : )
And I wonder if we could use GRANSAC for cylinder surface fitting?

As far as I know, cylinder surface equation at least will need 1. direction vector / axis, 2. point that direction vector / axis pass through, 3. radius, at least 7 parameters?
But I dont know how to write the model.

pyRANSAC-3D has an implementation, but result is not good.

Thank you.
