Complete Gaussian Splats from a Single Image with Denoising Diffusion Models

Ziwei Liao, Mohamed Sayed, Steven L. Waslander +3

Gaussian splatting typically requires dense observations of the scene and can fail to reconstruct occluded and unobserved areas. We propose a latent diffusion model to reconstruct…

Toward General Object-level Mapping from Sparse Views with 3D Diffusion Priors

Ziwei Liao, Binbin Xu, Steven L. Waslander

Object-level mapping builds a 3D map of objects in a scene with detailed shapes and poses from multi-view sensor observations. Conventional methods struggle to build complete shape…

Multiple View Geometry Transformers for 3D Human Pose Estimation

Ziwei Liao, Jialiang Zhu, Chunyu Wang +2

In this work, we aim to improve the 3D reasoning ability of Transformers in multi-view 3D human pose estimation. Recent works have focused on end-to-end learning-based transformer…

Uncertainty-aware 3D Object-Level Mapping with Deep Shape Priors

Ziwei Liao, Jun Yang, Jingxing Qian +2

3D object-level mapping is a fundamental problem in robotics, which is especially challenging when object CAD models are unavailable during inference. In this work, we propose a fr…

Multi-view 3D Object Reconstruction and Uncertainty Modelling with Neural Shape Prior

Ziwei Liao, Steven L. Waslander

3D object reconstruction is important for semantic scene understanding. It is challenging to reconstruct detailed 3D shapes from monocular images directly due to a lack of depth in…

SO-SLAM: Semantic Object SLAM with Scale Proportional and Symmetrical Texture Constraints

Ziwei Liao, Yutong Hu, Jiadong Zhang +3

Object SLAM introduces the concept of objects into Simultaneous Localization and Mapping (SLAM) and helps understand indoor scenes for mobile robots and object-level interactive ap…

Stereo Plane SLAM Based on Intersecting Lines

Xiaoyu Zhang, Wei Wang, Xianyu Qi +1

Plane feature is a kind of stable landmark to reduce drift error in SLAM system. It is easy and fast to extract planes from dense point cloud, which is commonly acquired from RGB-D…

Object-oriented SLAM using Quadrics and Symmetry Properties for Indoor Environments

Ziwei Liao, Wei Wang, Xianyu Qi +4

Aiming at the application environment of indoor mobile robots, this paper proposes a sparse object-level SLAM algorithm based on an RGB-D camera. A quadric representation is used a…

Coarse-To-Fine Visual Localization Using Semantic Compact Map

Ziwei Liao, Jieqi Shi, Xianyu Qi +5

Robust visual localization for urban vehicles remains challenging and unsolved. The limitation of computation efficiency and memory size has made it harder for large-scale applicat…
