Zero-BEV: Zero-shot Projection of Any First-Person Modality to BEV Maps

no code implementations21 Feb 2024 Gianluca Monaci, Leonid Antsfeld, Boris Chidlovskii, Christian Wolf

Bird's-eye view (BEV) maps are an important geometrically structured representation widely used in robotics, in particular self-driving vehicles and terrestrial robots.

Learning to navigate efficiently and precisely in real environments

no code implementations25 Jan 2024 Guillaume Bono, Hervé Poirier, Leonid Antsfeld, Gianluca Monaci, Boris Chidlovskii, Christian Wolf

In the context of autonomous navigation of terrestrial robots, the creation of realistic models for agent dynamics and sensing is a widespread habit in the robotics literature and in commercial applications, where they are used for model based control and/or for localization and mapping.

End-to-End (Instance)-Image Goal Navigation through Correspondence as an Emergent Phenomenon

no code implementations28 Sep 2023 Guillaume Bono, Leonid Antsfeld, Boris Chidlovskii, Philippe Weinzaepfel, Christian Wolf

The main challenge lies in learning compact representations generalizable to unseen environments and in learning high-capacity perception modules capable of reasoning on high-dimensional input.

Learning with a Mole: Transferable latent spatial representations for navigation without reconstruction

no code implementations6 Jun 2023 Guillaume Bono, Leonid Antsfeld, Assem Sadek, Gianluca Monaci, Christian Wolf

Agents navigating in 3D environments require some form of memory, which should hold a compact and actionable representation of the history of observations useful for decision taking and planning.

CroCo v2: Improved Cross-view Completion Pre-training for Stereo Matching and Optical Flow

1 code implementation ICCV 2023 Philippe Weinzaepfel, Thomas Lucas, Vincent Leroy, Yohann Cabon, Vaibhav Arora, Romain Brégier, Gabriela Csurka, Leonid Antsfeld, Boris Chidlovskii, Jérôme Revaud

Despite impressive performance for high-level downstream tasks, self-supervised pre-training methods have not yet fully delivered on dense geometric vision tasks such as stereo matching or optical flow.

CroCo: Self-Supervised Pre-training for 3D Vision Tasks by Cross-View Completion

1 code implementation19 Oct 2022 Philippe Weinzaepfel, Vincent Leroy, Thomas Lucas, Romain Brégier, Yohann Cabon, Vaibhav Arora, Leonid Antsfeld, Boris Chidlovskii, Gabriela Csurka, Jérôme Revaud

More precisely, we propose the pretext task of cross-view completion where the first input image is partially masked, and this masked content has to be reconstructed from the visible content and the second image.

Magnetic Field Sensing for Pedestrian and Robot Indoor Positioning

no code implementations26 Aug 2021 Leonid Antsfeld, Boris Chidlovskii

For the first setup, we revise the state of the art approaches and propose a novel extended pipeline to benefit from the presence of magnetic anomalies in indoor environment created by different ferromagnetic objects.

Deep Smartphone Sensors-WiFi Fusion for Indoor Positioning and Tracking

no code implementations21 Nov 2020 Leonid Antsfeld, Boris Chidlovskii, Emilio Sansano-Sansano

We address the indoor localization problem, where the goal is to predict user's trajectory from the data collected by their smartphone, using inertial sensors such as accelerometer, gyroscope and magnetometer, as well as other environment and network sensors such as barometer and WiFi.
