BidaSius

I'm training ISSF 10m air pistol and i train at home - so mostly after 10shots i had to go 10m and change paper target. It was wrong:)
So i've created this :)
Its not preety but its cheap and it works.
Total cost i would say is around 200PLN which is like 50$.
All you need is :
1 good usb camera
1 computer
1 10m usb cable
1 used/dead ink printer
1 arduino
power source
usb hub
maybe 3d printer for camera mount print - mine its crap
some electronic and mechanical skills

I have no time to develop it further ... maybe some of you will :)
If somebody has some questions please let me know , feel free to use it privately
Of course everything is in Polish :)

Details:
It uses webcam => grabs images => process them(with emgucv library) => show result on screen => scroll paper on target => repeat

It can use any black paper roll even packing paper - but best one is kruger...

About processing library ... i completly dont know anything about image procesing .... so it was all done by trial and error method
