Cheap camera tracking for virtual production?

So here’s my question, is there any camera tracking system for virtual production involving kinects?, smartphone ARcore?, AI?, Computer Vision?, my goal is to have a camera tracked and real time compositing in unreal engine. There’s an example on the kinect’s documentation that tracks the camera’s position and rotation in real time, but i dont know how to port it to unreal neither do i think it is possible. I haven’t seen anybody doing this so i figured i would try, for free.

For now i just need the camera tracking system as i already know how to do real time compositing in ue.

Any suggestions will be appreciated.
