3DGS-Calib: 3D Gaussian Splatting for Multimodal SpatioTemporal Calibration

no code implementations18 Mar 2024 Quentin Herau, Moussab Bennehar, Arthur Moreau, Nathan Piasco, Luis Roldao, Dzmitry Tsishkou, Cyrille Migniot, Pascal Vasseur, Cédric Demonceaux

We introduce 3DGS-Calib, a new calibration method that relies on the speed and rendering accuracy of 3D Gaussian Splatting to achieve multimodal spatiotemporal calibration that is accurate, robust, and with a substantial speed-up compared to methods relying on implicit neural representations.

SWAG: Splatting in the Wild images with Appearance-conditioned Gaussians

no code implementations15 Mar 2024 Hiba Dahmani, Moussab Bennehar, Nathan Piasco, Luis Roldao, Dzmitry Tsishkou

To tackle this, we extend over 3D Gaussian Splatting to handle unstructured image collections.

SCILLA: SurfaCe Implicit Learning for Large Urban Area, a volumetric hybrid solution

no code implementations15 Mar 2024 Hala Djeghim, Nathan Piasco, Moussab Bennehar, Luis Roldão, Dzmitry Tsishkou, Désiré Sidibé

SCILLA's hybrid architecture models two separate implicit fields: one for the volumetric density and another for the signed distance to the surface.

RoDUS: Robust Decomposition of Static and Dynamic Elements in Urban Scenes

no code implementations14 Mar 2024 Thang-Anh-Quan Nguyen, Luis Roldão, Nathan Piasco, Moussab Bennehar, Dzmitry Tsishkou

The task of separating dynamic objects from static environments using NeRFs has been widely studied in recent years.

SOAC: Spatio-Temporal Overlap-Aware Multi-Sensor Calibration using Neural Radiance Fields

no code implementations27 Nov 2023 Quentin Herau, Nathan Piasco, Moussab Bennehar, Luis Roldão, Dzmitry Tsishkou, Cyrille Migniot, Pascal Vasseur, Cédric Demonceaux

In this paper, we leverage the ability of Neural Radiance Fields (NeRF) to represent different sensors modalities in a common volumetric representation to achieve robust and accurate spatio-temporal sensor calibration.
