Question Fast moving ball detection

Hi,

I was wondering if someone could guide me if the following functionality is possible using Unity AR foundation?

Are there any samples I can refer to? It is imperative that the solution is able to detect fast moving (balls) in real-time like basketball dribbling or baseball (I know it’s a stretch, but I need to know if the phone cameras are fast enough to do it or we need to do post processing using opencv etc).

Would appreciate some advice.

Thanks!

 

i'd think opencv is the way.. even the google ar instant placement is rather slow,
https://developers.google.com/ar/develop/java/instant-placement/overview

also,
since camera is not moving, you could maybe fake it, detect if target area color changes (to near ball color..)
or in shader could do color thresholding and blob detection for those pixels, to possibly get actual ball position..

but of course those would fail if background has same colors

 

I see - what about unity AR Foundation 2d image tracking?
