How can the parameters of the calibrated fisheye camera model in matlab and opencv be converted to each other?

63 views (last 30 days)
as far as i know, Computer Vision Toolbox calibration algorithm uses the fisheye camera model proposed by Scaramuzza , while opencv library uses the fisheye model by Juho Kannala and Sami Brandt. If I have already calibrated the fisheyeIntrinsic parameters in the cv toolbox, how do I convert them into the corresponding opencv 4 polynomial coefficients and the intrinsic camera matrix?(and vice versa)your answer would be greatly appreciate!
Note: since Matlab R2021b,TMW has introduced cameraIntr​insicsFrom​OpenCV, cameraIntr​insicsTo​OpenCV ,etc functions,but these functions are only for pinhole cameras, not fisheye large aberration camera models
