How to tracking person with bird-eye camera

edit

I'm current working on tracking person with bird-eye camera (360-degree image source without distort) project and I want to tracking person and walk line.

I've research about one week and there is no information or sample project that work with bird-eye camera on internet, so I've contact Vision & A.I company about is it possible to tracking person on bird-eye camera, they told me their current algorithm also cannot deal with bird-eye lens without undisort.

So I need the suggestion how to work on bird-eye camera (I've tried to tracking like tracking on normal camera but it's not work).
