Spatiotemporal Calibration of Doppler Velocity Logs for Underwater Robots
Hongxu Zhao, Guangyang Zeng, Yunling Shao +2
The calibration of extrinsic parameters and clock offsets between sensors for high-accuracy performance in underwater SLAM systems remains insufficiently explored. Existing methods…
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…
Consistent and Optimal Solution to Camera Motion Estimation
Guangyang Zeng, Qingcheng Zeng, Xinghan Li +4
Given 2D point correspondences between an image pair, inferring the camera motion is a fundamental issue in the computer vision community. The existing works generally set out from…
RSS-Based Localization: Ensuring Consistency and Asymptotic Efficiency
Shenghua Hu, Guangyang Zeng, Wenchao Xue +3
We study the problem of signal source localization using received signal strength measurements. We begin by presenting verifiable geometric conditions for sensor deployment that en…
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,…
