Efficient Minimal Solvers for Visual-Inertial Relative Pose Estimation in Multi-Camera Systems
Tao Li, Zhenbao Yu, Banglei Guan +2
Estimating the relative poses of multi-camera systems is a fundamental problem in computer vision, with critical applications in autonomous vehicles, mobile devices, and unmanned a…
An Opticalmechanics Framework for Dynamic Estimation of Multibody Systems
Banglei Guan, Xuanyu Bai, Qingquan Chen +5
Conventional dynamics analysis of the human body is often constrained by the need for contact force and torque sensors and controlled laboratory environments. To address this issue…
Minimal Solvers for Full-DoF Motion Estimation from Asynchronous Differential SfM
Shuo Pan, Banglei Guan, Bin Li +5
As a bio-inspired intelligent sensor, event cameras have introduced a new paradigm in the intelligent perception of spatiotemporal information and visual motion estimation, charact…
High Dynamic Range Imaging Based on an Asymmetric Event-SVE Camera System
Pengju Sun, Banglei Guan, Jing Tao +4
High dynamic range (HDR) imaging under extreme illumination remains challenging for conventional cameras due to overexposure. Event cameras provide microsecond temporal resolution…
A Minimal Solver for Relative Pose Estimation with Unknown Focal Length from Two Affine Correspondences
Zhenbao Yu, Shirong Ye, Ronghe Jin +4
In this paper, we aim to estimate the relative pose and focal length between two views with known intrinsic parameters except for an unknown focal length from two affine correspond…
LECalib: Line-Based Event Camera Calibration
Zibin Liu, Banglei Guan, Yang Shang +3
Camera calibration is an essential prerequisite for event-based vision applications. Current event camera calibration methods typically involve using flashing patterns, reconstruct…
