Tracking a large number of objects

There are a large number of real objects (about 200 pieces). Which need to be tracked within one application. I don’t understand how best to do this. Digitize these objects and make 3D models and track them, simply track photographs (for example, take 4-6 photographs of each object and track them) or there is some other method. Please tell me who solved a similar problem. How can you implement tracking of a large number of objects within one application?

i’d look into those AI solutions, YOLO or others,
saw one recently that tracked hundreds of people or cars in realtime… (but forgot the name)

Perhaps I did not formulate the problem quite correctly. I’m sorry.
In my case the objects are known in advance. There will be only one object in the camera at a time, I need to identify it among all and do certain actions

And my question is how best to digitize a large number of objects (make models based on them, photographs, markers of some kind) and identify them

Currently ARKit is the only AR Foundation platform that supports object tracking. I recommend that you try their sample app and see if their tracking meets your needs: Scanning and detecting 3D objects | Apple Developer Documentation

If ARKit is suitable, you may see performance degrade in AR Foundation if you try to add all 200 objects to the same reference object library: Object tracking | Apple ARKit XR Plugin | 5.1.5. If possible I would try to logically separate them into multiple libraries and only load one library at a time.
