LoopSplat: Loop Closure by Registering 3D Gaussian Splats

1 code implementation19 Aug 2024 Liyuan Zhu, Yue Li, Erik Sandström, Shengyu Huang, Konrad Schindler, Iro Armeni

However, existing 3DGS-based methods fail to address the global consistency of the scene via loop closure and/or global bundle adjustment.

VF-NeRF: Learning Neural Vector Fields for Indoor Scene Reconstruction

1 code implementation16 Aug 2024 Albert Gassol Puigjaner, Edoardo Mello Rella, Erik Sandström, Ajad Chhatkuli, Luc van Gool

Concretely, we develop a novel density-VF relationship and a training scheme that allows us to learn VF via volume rendering By doing this, VF-NeRF can model large planar surfaces and sharp corners accurately.

Splat-SLAM: Globally Optimized RGB-only SLAM with 3D Gaussians

1 code implementation26 May 2024 Erik Sandström, Keisuke Tateno, Michael Oechsle, Michael Niemeyer, Luc van Gool, Martin R. Oswald, Federico Tombari

In response, we propose the first RGB-only SLAM system with a dense 3D Gaussian map representation that utilizes all benefits of globally optimized tracking by adapting dynamically to keyframe pose and depth updates by actively deforming the 3D Gaussian map.

GlORIE-SLAM: Globally Optimized RGB-only Implicit Encoding Point Cloud SLAM

1 code implementation28 Mar 2024 Ganlin Zhang, Erik Sandström, Youmin Zhang, Manthan Patel, Luc van Gool, Martin R. Oswald

To alleviate this issue, with the aid of a monocular depth estimator, we introduce a novel DSPO layer for bundle adjustment which optimizes the pose and depth of keyframes along with the scale of the monocular depth.

Point-SLAM: Dense Neural Point Cloud-based SLAM

2 code implementations ICCV 2023 Erik Sandström, Yue Li, Luc van Gool, Martin R. Oswald

We propose a dense neural simultaneous localization and mapping (SLAM) approach for monocular RGBD input which anchors the features of a neural scene representation in a point cloud that is iteratively generated in an input-dependent data-driven manner.

Learning Online Multi-Sensor Depth Fusion

1 code implementation7 Apr 2022 Erik Sandström, Martin R. Oswald, Suryansh Kumar, Silvan Weder, Fisher Yu, Cristian Sminchisescu, Luc van Gool

Multi-sensor depth fusion is able to substantially improve the robustness and accuracy of 3D reconstruction methods, but existing techniques are not robust enough to handle sensors which operate with diverse value ranges as well as noise and outlier statistics.
