Monocular Visual-Inertial Odometry for Agricultural Environments

open access: yesIEEE Access, 2022
The accuracy of autonomous robot localization using a monocular visual-inertial odometry system (VIO) is significantly reduced in an agricultural environment compared to an urban and indoor environment due to the unstructured scenes with unstable ...

ESVO2: Direct Visual-Inertial Odometry With Stereo Event Cameras [PDF]

open access: yesIEEE Transactions on robotics
Event-based visual odometry is a specific branch of visual simultaneous localization and mapping (SLAM) techniques, which aims at solving tracking and mapping subproblems (typically in parallel), by exploiting the special working principles of ...

A Tutorial on Quantitative Trajectory Evaluation for Visual(-Inertial) Odometry

open access: yesIEEE/RJS International Conference on Intelligent RObots and Systems, 2018
In this tutorial, we provide principled methods to quantitatively evaluate the quality of an estimated trajectory from visual(-inertial) odometry (VO/VIO), which is the foundation of benchmarking the accuracy of different algorithms.

Selective Sensor Fusion for Neural Visual-Inertial Odometry [PDF]

open access: yes2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2019
Deep learning approaches for Visual-Inertial Odometry (VIO) have proven successful, but they rarely focus on incorporating robust fusion strategies for dealing with imperfect input sensory data. We propose a novel end-to-end selective sensor fusion framework for monocular VIO, which fuses monocular images and inertial measurements in order to estimate ...

Ultra-Wideband Aided Fast Localization and Mapping System

open access: yes, 2017
This paper proposes an ultra-wideband (UWB) aided localization and mapping system that leverages on inertial sensor and depth camera. Inspired by the fact that visual odometry (VO) system, regardless of its accuracy in the short term, still faces ...

Direct visual-inertial odometry with semi-dense mapping [PDF]

open access: yesComputers & Electrical Engineering, 2018
The paper presents a direct visual-inertial odometry system. In particular, a tightly coupled nonlinear optimization based method is proposed by integrating the recent advances in direct dense tracking and Inertial Measurement Unit (IMU) pre-integration, and a factor graph optimization is adapted to estimate the pose of the camera and rebuild a semi ...

Comparison of Three Off-the-Shelf Visual Odometry Systems

open access: yesRobotics, 2020
Positioning is an essential aspect of robot navigation, and visual odometry an important technique for continuous updating the internal information about robot position, especially indoors without GPS (Global Positioning System). Visual odometry is using

Attention and Anticipation in Fast Visual-Inertial Navigation [PDF]

open access: yes, 2018
We study a Visual-Inertial Navigation (VIN) problem in which a robot needs to estimate its state using an on-board camera and an inertial sensor, without any prior knowledge of the external environment.
