Export distortion parameters of image distortion in OpenCV format

My special wish is to export the distortion coefficients for the use with OpenCV python library. The format is discribed here: https://docs.opencv.org/4.x/d9/d0c/group__calib3d.html, so I want (k1, k2, p1, p2, k3, k4, k5, k6, ...). 
I have seen that in filter/lens corrections one can export a .lcs file as a distortion preset. But after an online viewer I saw no parameters listed there directly.
The idea is to distort the image in photoshop to get an estimation of the image distortion that I have to know for data preprocessing in python. The problem is that I cannot put a chessboard infront of the webcams as it would be normally done.

So is this possible somehow? With warping and or with a plugin?
