AIR-HLoc: Adaptive Image Retrieval for Efficient Visual Localisation

no code implementations27 Mar 2024 Changkun Liu, Huajian Huang, Zhengyang Ma, Tristan Braud

State-of-the-art (SOTA) hierarchical localisation pipelines (HLoc) rely on image retrieval (IR) techniques to establish 2D-3D correspondences by selecting the $k$ most similar images from a reference image database for a given query image.

360Loc: A Dataset and Benchmark for Omnidirectional Visual Localization with Cross-device Queries

no code implementations29 Nov 2023 Huajian Huang, Changkun Liu, Yipeng Zhu, Hui Cheng, Tristan Braud, Sai-Kit Yeung

We propose a virtual camera approach to generate lower-FoV query frames from 360$^\circ$ images, which ensures a fair comparison of performance among different query types in visual localization tasks.

Photo-SLAM: Real-time Simultaneous Localization and Photorealistic Mapping for Monocular, Stereo, and RGB-D Cameras

no code implementations28 Nov 2023 Huajian Huang, Longwei Li, Hui Cheng, Sai-Kit Yeung

In addition to actively densifying hyper primitives based on geometric features, we further introduce a Gaussian-Pyramid-based training method to progressively learn multi-level features, enhancing photorealistic mapping performance.

360VOT: A New Benchmark Dataset for Omnidirectional Visual Object Tracking

1 code implementation ICCV 2023 Huajian Huang, Yinzhe Xu, Yingshu Chen, Sai-Kit Yeung

360{\deg} images can provide an omnidirectional field of view which is important for stable and long-term scene perception.

360Roam: Real-Time Indoor Roaming Using Geometry-Aware 360$^\circ$ Radiance Fields

no code implementations4 Aug 2022 Huajian Huang, Yingshu Chen, Tianjia Zhang, Sai-Kit Yeung

Subsequently, we assign local radiance fields through an adaptive divide-and-conquer strategy based on the recovered geometry.

Dual-SLAM: A framework for robust single camera navigation

no code implementations23 Sep 2020 Huajian Huang, Wen-Yan Lin, Siying Liu, Dong Zhang, Sai-Kit Yeung

As local pose estimation is ill-conditioned, local pose estimation failures happen regularly, making the overall SLAM system brittle.
