Hi!
You need a 3D tracked camera. In transform menu choose PointsTo3D node. More info in the node help. If you are using NukeX, you can use camera tracker node, right click on the desired point and you will know it's 3d position. You can use your 2D tracks in camera tracker as user features, too.

I hope it can help you.
Bye!
