NeuraLoc: Visual Localization in Neural Implicit Map with Dual Complementary Features

no code implementations8 Mar 2025 Hongjia Zhai, Boming Zhao, Hai Li, Xiaokun Pan, Yijia He, Zhaopeng Cui, Hujun Bao, Guofeng Zhang

Specifically, to enforce geometric constraints and reduce storage requirements, we implicitly learn a 3D keypoint descriptor field, avoiding the need to explicitly store point-wise features.

SplatLoc: 3D Gaussian Splatting-based Visual Localization for Augmented Reality

no code implementations21 Sep 2024 Hongjia Zhai, Xiyu Zhang, Boming Zhao, Hai Li, Yijia He, Zhaopeng Cui, Hujun Bao, Guofeng Zhang

Visual localization plays an important role in the applications of Augmented Reality (AR), which enable AR devices to obtain their 6-DoF pose in the pre-build map in order to render virtual content in real scenes.

Vox-Fusion++: Voxel-based Neural Implicit Dense Tracking and Mapping with Multi-maps

no code implementations19 Mar 2024 Hongjia Zhai, Hai Li, Xingrui Yang, Gan Huang, Yuhang Ming, Hujun Bao, Guofeng Zhang

In this paper, we introduce Vox-Fusion++, a multi-maps-based robust dense tracking and mapping system that seamlessly fuses neural implicit representations with traditional volumetric fusion techniques.

Vox-Fusion: Dense Tracking and Mapping with Voxel-based Neural Implicit Representation

1 code implementation28 Oct 2022 Xingrui Yang, Hai Li, Hongjia Zhai, Yuhang Ming, Yuqian Liu, Guofeng Zhang

In this work, we present a dense tracking and mapping system named Vox-Fusion, which seamlessly fuses neural implicit representations with traditional volumetric fusion methods.

Vox-Surf: Voxel-based Implicit Surface Representation
