Image-based Geolocalization by Ground-to-2.5D Map Matching

1 code implementation11 Aug 2023 Mengjie Zhou, Liu Liu, Yiran Zhong, Andrew Calway

In this paper, we lift cross-view matching to a 2. 5D space, where heights of structures (e. g., trees and buildings) provide geometric information to guide the cross-view matching.

iDF-SLAM: End-to-End RGB-D SLAM with Neural Implicit Mapping and Deep Feature Tracking

no code implementations16 Sep 2022 Yuhang Ming, Weicai Ye, Andrew Calway

The neural implicit mapper is trained on-the-fly, while though the neural tracker is pretrained on the ScanNet dataset, it is also finetuned along with the training of the neural implicit mapper.

Dual-Domain Image Synthesis using Segmentation-Guided GAN

1 code implementation19 Apr 2022 Dena Bazazian, Andrew Calway, Dima Damen

We build on the successes of few-shot StyleGAN and single-shot semantic segmentation to minimise the amount of training required in utilising two domains.

FD-SLAM: 3-D Reconstruction Using Features and Dense Matching

no code implementations25 Mar 2022 Xingrui Yang, Yuhang Ming, Zhaopeng Cui, Andrew Calway

It is well known that visual SLAM systems based on dense matching are locally accurate but are also susceptible to long-term drift and map corruption.

CGiS-Net: Aggregating Colour, Geometry and Implicit Semantic Features for Indoor Place Recognition

1 code implementation4 Feb 2022 Yuhang Ming, Xingrui Yang, Guofeng Zhang, Andrew Calway

We describe a novel approach to indoor place recognition from RGB point clouds based on aggregating low-level colour and geometry features with high-level implicit semantic features.

Object-Augmented RGB-D SLAM for Wide-Disparity Relocalisation

1 code implementation5 Aug 2021 Yuhang Ming, Xingrui Yang, Andrew Calway

During the map construction, we use a pre-trained neural network to detect objects and estimate 6D poses from RGB-D data.

You Are Here: Geolocation by Embedding Maps and Images

no code implementations ECCV 2020 Noe Samano, Mengjie Zhou, Andrew Calway

We present a novel approach to geolocalising panoramic images on a 2-D cartographic map based on learning a low dimensional embedded space, which allows a comparison between an image captured at a location and local neighbourhoods of the map.

Predicting Out-of-View Feature Points for Model-Based Camera Pose Estimation

no code implementations5 Mar 2018 Oliver Moolan-Feroze, Andrew Calway

In this work we present a novel framework that uses deep learning to predict object feature points that are out-of-view in the input image.

Automated Map Reading: Image Based Localisation in 2-D Maps Using Binary Semantic Descriptors

no code implementations2 Mar 2018 Pilailuck Panphattarasap, Andrew Calway

We describe a novel approach to image based localisation in urban environments using semantic matching between images and a 2-D map.

Visual place recognition using landmark distribution descriptors

no code implementations15 Aug 2016 Pilailuck Panphattarasap, Andrew Calway

Recent work by Suenderhauf et al. [1] demonstrated improved visual place recognition using proposal regions coupled with features from convolutional neural networks (CNN) to match landmarks between views.

HDRFusion: HDR SLAM using a low-cost auto-exposure RGB-D sensor

no code implementations4 Apr 2016 Shuda Li, Ankur Handa, Yang Zhang, Andrew Calway

We describe a new method for comparing frame appearance in a frame-to-model 3-D mapping and tracking system using an low dynamic range (LDR) RGB-D camera which is robust to brightness changes caused by auto exposure.
