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*, Andrew Davison (*Equal Contribution)

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.

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

@eric_dexheimer @AjdDavison Hey @rmurai0610 @eric_dexheimer, very cool modeling of the backend with a generic camera model! When do you guys plan to release the code?

@eric_dexheimer @AjdDavison Thanks Nikhil! We're planning on releasing the code early next year

@eric_dexheimer @AjdDavison Is this also the first time where we can virtually see the entire DRL office? haha Congrats on the amazing results!

@eric_dexheimer @AjdDavison Thank you! And yeah probably the first time we’ve managed to reconstruct the entire lab

@eric_dexheimer @AjdDavison do you plan to share the source code?

@eric_dexheimer @AjdDavison Yes, we're planning on releasing the code early next year

@eric_dexheimer @AjdDavison Idiot here 🤚 What sort of computer is required to run this? Can it be done real time?
