Number recognition on bingo balls

Job ID: 37488481

Budget: €30 – €250 EUR

I need to create a function in C++ that returns the number printed on bingo balls that will be shown by a camera.
To do this, you can use OpenCV, AI or whatever you think is best.
The project must work in **QT Creator**, which is the IDE we use.
Bingo balls can be four different shapes, so I am attaching a .zip with the four models that must be read.
Also included in the same .zip file is a video of how the balls can be presented in the camera.
The balls can be different colors.
Each of the balls has twelve impressions of the number. This ensures that at least one print of the number will appear complete in any position on the ball.
I can provide any image/video or any type of visual material of the balls.
The program will finally receive the image from a camera and every time a ball appears in it, it should be able to recognize the number.
Thanks for reading and thanks for your interest.
