LAMP tracks 3D human motion from egocentric multi-camera headsets via early disentanglement of observer and target motion. Using known device 6-DoF motion and calibration, 2D body keypoints from all cameras over a temporal window are lifted into a unified 3D world reference frame, and an end-to-end trained spatio-temporal transformer fits 3D human motion directly to this 3D ray cloud. This "lift-then-fit" approach achieves state-of-the-art results on monocular benchmarks while significantly outperforming baselines on the targeted egocentric setting.
