Introducing MASt3R-SLAM, the first real-time monocular dense SLAM with MASt3R as a foundation. Easy to use like DUSt3R/MASt3R, from an uncalibrated RGB video it recovers accurate, globally consistent poses & a dense map. With @eric_dexheimer*, @AjdDavison (*Equal Contribution)

π Excited to share CausNVS: Autoregressive Multi-view Diffusion for Flexible 3D Novel View Synthesis! Letβs recon 3D world generatively. CausNVS handles any number of input views, synthesizes novel views autoregressively, enables interactive streaming and flexible N-to-M NVS.

Well done to Riku and @eric_dexheimer on Best Demo Honourable Mention for MASt3R-SLAM at #CVPR2025. That's 3 best demo awards in the past 2 years at CVPR from our lab! (Gaussian Splatting SLAM won Best Demo in 2024 and SuperPrimitive got Honourable Mention). #DemosNotTables
We (with @eric_dexheimer) will be demoing MASt3R-SLAM @CVPR today 16:00-18:00, ExHall B, 9 Come and see the limits of our real-time monocular dense SLAM! Weβll also be presenting our poster #83 on Sat 14th from 17:00-19:00. See you soon!

Visual SLAM has made major success in static scenes β now letβs explore the dynamic world we live in! At #CVPR2025, we introduce 4DTAM, 4D Tracking & Mapping using dynamic surface Gaussians optimized through diff. rendering. https://t.co/TJ15J2QP12 w/ @BaeGwangbin @AjdDavison

Weβve had fun testing the limits of MASt3R-SLAM on in-the-wild videos. Hereβs the drone video of a Minnesota bowling alley that weβve always wanted to reconstruct! Different scene scales, dynamic objects, specular surfaces, and fast motion.
MASt3R-SLAM code release! https://t.co/VFc4zyMdA3 Try it out on videos or with a live camera Work with @eric_dexheimer*, @AjdDavison (*Equal Contribution)

For robustness, MASt3R-SLAM performs relocalisation allowing it to handle the kidnapped robot problem. As a purely monocular SLAM, it loses track when the cameraβs view is obstructed, but as soon as the view is unblocked, it immediately relocalises and resumes mapping.

We use MASt3R's two-view prior as our only network with no fine-tuning. By leveraging this 3D prior and making minimal assumptions on the camera model, we can handle dynamically changing zoom. Efficient test-time optimisation and loop closure enable large-scale consistency.

We'll be presenting "Distributed Simultaneous Localisation and Auto-Calibration using GBP" at #IROS2024 We show that distributed GBP can be effectively used to localise and auto-calibrate many robots. Please come to our presentation (Wed 17:30 Room 11) if you're around!

We won Best Demo at #CVPR2024 for Gaussian Splatting SLAM (@HideMatsu82 + @rmurai0610). Also: Best Demo Honourable Mention for SuperPrimitives (@makezur + @BaeGwangbin)! Proud of our whole group at @ICComputing. Demos make big impact, and are also fun!

Realtime, live interaction is what we enjoy most for SLAM researchπ Check out Gaussian Splatting SLAM (Highlight) demo and poster in #CVPR! We (w/ @rmurai0610) show challenging monocular setup, and of course stereo/rgbd too. Thu, Arch 4 Demo: 10:30~17:00 (CDE #12), Poster:
Our CVPR paper "Gaussian Splatting SLAM" is selected as a highlight! We just released the speed-up version of the code. https://t.co/k4N9qlBpds This week we (@rmurai0610, @AjdDavison) are in ICRA for a live demo (EXPO) and a spotlight talk (@robo_nerf) of the method. See you!
