HiP3R Stitches Long Video Into One Coherent 3D Scene Across Thousands of Frames
ccloy · x · 2026-10-26
HiP3R pieces together local 3D reconstructions from long videos into a single coherent 3D scene consistent across thousands of frames. The core challenge: short segments look fine individually but drift and misalign when stitched, especially when revisiting the same location.
Project page, paper, and code are all open-sourced.
