How (how) to read several QR codes from the surface?

Question

OpenCV

Hello!
Are there ready -made open-source software solutions for reading multiple QR codes from a surface in one iteration?
That is, in other words, we have a sheet (or a package) with n-pieces of QR codes on it, we need to read them all by the camera in one pass.
Preferably in python or javascript

Answer 1

We need to find all the objects (objects labeling) and decode them one by one.

Answer 2

The question is about everything and nothing at once. Most likely, you need to find a ready-made implementation of a QR recognizer and check whether it supports the mode of such multiple recognition.
