GeVI-SLAM: Gravity-Enhanced Stereo Visua Inertial SLAM for Underwater Robots
Yuan Shen, Yuze Hong, Guangyang Zeng +4
Accurate visual inertial simultaneous localization and mapping (VI SLAM) for underwater robots remains a significant challenge due to frequent visual degeneracy and insufficient in…
AquaticVision: Benchmarking Visual SLAM in Underwater Environment with Events and Frames
Yifan Peng, Yuze Hong, Ziyang Hong +2
Many underwater applications, such as offshore asset inspections, rely on visual inspection and detailed 3D reconstruction. Recent advancements in underwater visual SLAM systems fo…
Bias-Eliminated PnP for Stereo Visual Odometry: Provably Consistent and Large-Scale Localization
Guangyang Zeng, Yuan Shen, Ziyang Hong +4
In this paper, we first present a bias-eliminated weighted (Bias-Eli-W) perspective-n-point (PnP) estimator for stereo visual odometry (VO) with provable consistency. Specifically,…
NavigateDiff: Visual Predictors are Zero-Shot Navigation Assistants
Yiran Qin, Ao Sun, Yuze Hong +2
Navigating unfamiliar environments presents significant challenges for household robots, requiring the ability to recognize and reason about novel decoration and layout. Existing r…
BESTAnP: Bi-Step Efficient and Statistically Optimal Estimator for Acoustic-n-Point Problem
Wenliang Sheng, Hongxu Zhao, Lingpeng Chen +6
We consider the acoustic-n-point (AnP) problem, which estimates the pose of a 2D forward-looking sonar (FLS) according to n 3D-2D point correspondences. We explore the nature of th…
