Hierarchical pose graphs stitch long videos into 3D maps
What is HiP3R: Hierarchical Pose Graphs for Long-Horizon 3D Reconstruction?
HiP3R splits hour-long video into overlapping short clips, runs a feed-forward network on each, and merges the results with a hierarchical pose graph. This yields a full 3D reconstruction while keeping memory and compute modest.
Who it is for
Anyone building AR, robotics, or large-scale mapping can now generate detailed 3D scenes without needing massive GPUs.
