Can I use pose estimation to track people in 3D space?

At this time, Pose Estimation only tracks the movements and position of people in two dimensions. The location of keypoints are returned as (X, Y) coordinates relative to image boundaries.

How do I take the current position and draw external lines with respect to that point from that keypoint? I would like to detect the shoulder keypoints and draw horizontal and vertical lines extending from that.

Do you mind created a new topic with this question? I don’t think it related to 3D pose estimation.
