RKHS-BA: A Robust Correspondence-Free Multi-View Registration Framework with Semantic Point Clouds
Ray Zhang, Jingwei Song, Xiang Gao +5
This work reports a novel multi-frame Bundle Adjustment (BA) framework called RKHS-BA. It uses continuous landmark representations that encode RGB-D/LiDAR and semantic observations…
Colmap-PCD: An Open-source Tool for Fine Image-to-point cloud Registration
Chunge Bai, Ruijie Fu, Xiang Gao
State-of-the-art techniques for monocular camera reconstruction predominantly rely on the Structure from Motion (SfM) pipeline. However, such methods often yield reconstruction out…
Incremental Rotation Averaging Revisited
Xiang Gao, Hainan Cui, Yangdong Liu +1
In order to further advance the accuracy and robustness of the incremental parameter estimation-based rotation averaging methods, in this paper, a new member of the Incremental Rot…
Visual Localization Using Sparse Semantic 3D Map
Tianxin Shi, Shuhan Shen, Xiang Gao +1
Accurate and robust visual localization under a wide range of viewing condition variations including season and illumination changes, as well as weather and day-night variations, i…
Complete Scene Reconstruction by Merging Images and Laser Scans
Xiang Gao, Shuhan Shen, Lingjie Zhu +3
Image based modeling and laser scanning are two commonly used approaches in large-scale architectural scene reconstruction nowadays. In order to generate a complete scene reconstru…
LDSO: Direct Sparse Odometry with Loop Closure
Xiang Gao, Rui Wang, Nikolaus Demmel +1
In this paper we present an extension of Direct Sparse Odometry (DSO) to a monocular visual SLAM system with loop closure detection and pose-graph optimization (LDSO). As a direct…
CSfM: Community-based Structure from Motion
Hainan Cui, Shuhan Shen, Xiang Gao +1
Structure-from-Motion approaches could be broadly divided into two classes: incremental and global. While incremental manner is robust to outliers, it suffers from error accumulati…
