use sol2 to bind the opencv library

I want to use sol2 to bind the opencv library.
But I don't know how to implement it?
For example, reading and binarizing images.

cv::Mat src = cv::imread("demo.png", IMREAD_GRAYSCALE);
cv::Mat dst;
cv::threshold(src, dst, 128, 255, THRESH_BINARY);
cv::imshow("binary", dst);

Could you please write an example? How to bind opencv? I want to use lua to implement this C++ source code.
Thank you!

You take all the types, classes, functions and methods, and bind them one by one. That's how it's done for literally anything, not for OpenCV only.

Sol repo contains enough examples to help you do it, but if you dare, then good luck.
