A real-time dense SLAM system that builds 3D reconstructions of a scene from RGB video, using MASt3R 3D reconstruction priors. It runs on live camera feeds, MP4 videos, or image folders.

Hardware it needs, as the project states it
An NVIDIA GPU with CUDA (11.8, 12.1 or 12.4) matching the installed PyTorch build; the authors report running on an RTX 4090, and performance may differ on other GPUs. Ubuntu is the primarily tested OS; WSL is supported via a separate branch. A RealSense camera is needed only for the live demo.

Checked on GitHub on 6 Nov 2026.

Overview

What it does: Robotheca's summary

  • Performs dense simultaneous localization and mapping from monocular RGB input, including live RealSense cameras, MP4 videos, and image folders.
  • Uses pretrained MASt3R checkpoints, which must be downloaded separately into a checkpoints folder.
  • Includes scripts to download and evaluate on TUM-RGBD, 7-Scenes, EuRoC and ETH3D SLAM datasets.
  • Accepts known camera calibration through an intrinsics file, or runs without calibration.
  • Has a WSL variant on a separate windows branch that disables multiprocessing.
