EgoMo3R jointly reconstructs egocentric camera paths, scenes, and body motion from video. It alternates visual geometry and a learned motion prior so scene and movement constrain each other. On EgoExo4D, metric-scale mean Accuracy and Completion distances are 0.357 and 0.187, versus ViPE’s 0.905 and 0.819, supporting better scene reconstruction, not universal gains in camera-pose metrics.
