Built-in function for combining affine transformations in OpenCV?

Question

Is there a built-in function in Opencv that integrates affine transformations?
I can also write it myself, but if possible, I will use library functions.

Greetings.

Answer 1

Now I am doing this:

• I highlight the matrices a1, a2, r, all eyes are 3x3,
• I replace the top of the first two transformation matrices a1aff, a2aff.
• r = a2 * a1
• return the first two lines of r.

Now this decision will be implemented.
