Visual Localization Based on Torus-like Surfaces [PDF]

open access: yesSensors
Previous visual localization started from point correspondences (PCs) to estimate poses. This article takes the camera position as the entry point and finds that the camera position solution set rotates around an axis connected by two observed 3D points ...

Robust Visual Localization with Dynamic Uncertainty Management in Omnidirectional SLAM

open access: yesApplied Sciences, 2017
This work presents a robust visual localization technique based on an omnidirectional monocular sensor for mobile robotics applications. We intend to overcome the non-linearities and instabilities that the camera projection systems typically introduce ...

"Sitting too close to the screen can be bad for your ears": A study of audio-visual location discrepancy detection under different visual projections [PDF]

open access: yes, 2001
In this work, we look at the perception of event locality under conditions of disparate audio and visual cues. We address an aspect of the so called “ventriloquism effect” relevant for multi-media designers; namely, how auditory perception of event ...

Standalone and embedded stereo visual odometry based navigation solution [PDF]

open access: yes, 2015
© Cranfield University, 2014This thesis investigates techniques and designs an autonomous visual stereo based navigation sensor to improve stereo visual odometry for purpose of navigation in unknown environments. In particular, autonomous navigation in a

Effective venue image retrieval using robust feature extraction and model constrained matching for mobile robot localization [PDF]

open access: yes, 2011
This paper describes a novel system for mobile robot localization in an indoor environment, using concepts like homography and matching borrowed from the context of stereo and content-based image retrieval techniques (CBIR).

Direct Aerial Visual Geolocalization Using Deep Neural Networks

open access: yesRemote Sensing, 2021
Unmanned aerial vehicles (UAVs) must keep track of their location in order to maintain flight plans. Currently, this task is almost entirely performed by a combination of Inertial Measurement Units (IMUs) and reference to GNSS (Global Navigation ...

Sequence-Based Filtering for Visual Route-Based Navigation: Analyzing the Benefits, Trade-Offs and Design Choices

open access: yesIEEE Access, 2022
Visual Place Recognition (VPR) is the ability to correctly recall a previously visited place using visual information under environmental, viewpoint and appearance changes. An emerging trend in VPR is the use of sequence-based filtering methods on top of

Visual topometric localization [PDF]

open access: yes2011 IEEE Intelligent Vehicles Symposium (IV), 2011
One of the fundamental requirements of an autonomous vehicle is the ability to determine its location on a map. Frequently, solutions to this localization problem rely on GPS information or use expensive three dimensional (3D) sensors. In this paper, we describe a method for long-term vehicle localization based on visual features alone.

Semantic Visual Localization [PDF]

open access: yes2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018
Robust visual localization under a wide range of viewing conditions is a fundamental problem in computer vision. Handling the difficult cases of this problem is not only very challenging but also of high practical relevance, e.g., in the context of life-long localization for augmented reality or autonomous robots.

Visual localization for mobile surveillance [PDF]

open access: yes2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011
In this paper we propose a complete system that is able to accurately localize a mobile agent wearing a camera inside a known environment. The work leverages on a precomputed 3D structure to obtain 2D-3D correspondences and then orients the camera. Experiments in a challenging environment with a handmade ground-truth demonstrate sufficient accuracy to ...
