Translate track marker 2d position to empty in 3d space

Question

How do you transform a track marker to a empty in 3d space?

I only need the 2d position relative to the camera's view.

For a 3D track you need at least 8 markers to do a camera solve... Watch the wonderful tutorial "Track, Match, Blend" from Sebastian König. — Samoth, Jan 24 '17 at 12:41
That's just the thing I don't want/need a camera solve. Just a empty in 3d space to be in the same position as the track marker when viewed from camera view... — Willson, Jan 24 '17 at 12:47
Track, Match, Blend - 02 One Point Tracking... It's not possible to use a 3D empty with only 2D coordinates and a camera view. — Samoth, Jan 24 '17 at 13:00
Well I couldn't have misunderstood your comment more. Thanks. — Willson, Jan 24 '17 at 13:04
