How to detect active weapon in Pubg using CV?

[Tahsin]

No, I don't work on this script as its a lot of work for an unknown result. It may not work reliable at all at the end as I said the background of the hud where the weapon image is shown needs to be fully opaque for fast, simple and reliable detection.
Pickup the biggest weapon in game as all weapon images to compare should have the same width and height.
Now compare that rectangle area with the same area in your current screenshot.
you will see the background changes it colors depending on where you do the screenshot.

Yesi see that but there is an other idea to detect the weapon name is by opening the invantry you can see the weapon name
very clearly
