EscherNet: A Generative Model for Scalable View Synthesis

CVPR 2024poster

We introduce EscherNet a multi-view conditioned diffusion model for view synthesis. EscherNet learns implicit and generative 3D representations coupled with a specialised camera positional encoding allowing precise and continuous relative control of the camera transformation between an arbitrary num…

vMAP: Vectorised Object Mapping for Neural Field SLAM

CVPR 2023poster

We present vMAP, an object-level dense SLAM system using neural field representations. Each object is represented by a small MLP, enabling efficient, watertight object modelling without the need for 3D priors. As an RGB-D camera browses a scene with no prior information, vMAP detects object instance…

RINet: Efficient 3D Lidar-Based Place Recognition Using Rotation Invariant Neural Network

RA-L 2022

LiDAR-based place recognition (LPR) is one of the basic capabilities of robots, which can retrieve scenes from maps and identify previously visited locations based on 3D point clouds. As robots often pass the same place from different views, LPR methods are supposed to be robust to rotation, which i

HR-Depth: High Resolution Self-Supervised Monocular Depth Estimation

AAAI 2021technical

Self-supervised learning shows great potential in monocular depth estimation, using image sequences as the only source of supervision. Although people try to use the high-resolution image for depth estimation, the accuracy of prediction has not been significantly improved. In this work…

PocoNet: SLAM-oriented 3D LiDAR Point Cloud Online Compression Network

ICRA 2021poster

In this paper, we present PocoNet: Point cloud Online COmpression NETwork to address the task of SLAM-oriented compression. The aim of this task is to select a compact subset of points with high priority to maintain localization accuracy. The key insight is that points with high priority have simila…

SA-LOAM: Semantic-aided LiDAR SLAM with Loop Closure

ICRA 2021poster

LiDAR-based SLAM system is admittedly more accurate and stable than others, while its loop closure detection is still an open issue. With the development of 3D semantic segmentation for point cloud, semantic information can be obtained conveniently and steadily, essential for high-level intelligence…

SSC: Semantic Scan Context for Large-Scale Place Recognition

IROS 2021poster

Place recognition gives a SLAM system the ability to correct cumulative errors. Unlike images that contain rich texture features, point clouds are almost pure geometric information which makes place recognition based on point clouds challenging. Existing works usually encode low-level features such…

Semantic Segmentation-assisted Scene Completion for LiDAR Point Clouds

IROS 2021poster

Outdoor scene completion is a challenging issue in 3D scene understanding, which plays an important role in intelligent robotics and autonomous driving. Due to the sparsity of LiDAR acquisition, it is far more complex for 3D scene completion and semantic segmentation. Since semantic features can pro…

Semantic Graph Based Place Recognition for 3D Point Clouds

IROS 2020poster

Due to the difficulty in generating the effective descriptors which are robust to occlusion and viewpoint changes, place recognition for 3D point cloud remains an open issue. Unlike most of the existing methods that focus on extracting local, global, and statistical features of raw point clouds, our…
