Determining the location of an image without GPS based on cross-view matching. In most of the cases a database of satellite images is used to match the ground images to them.

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

zhoumengjie/2-5dmap-dataset 11 Aug 2023

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.

TBPos: Dataset for Large-Scale Precision Visual Localization

jboutell/tbpos 20 Feb 2023

Usually the query images have been acquired with a camera that differs from the imaging hardware used to collect the 3D database; consequently, it is hard to acquire accurate ground truth poses between query images and the 3D database.

Simple, Effective and General: A New Backbone for Cross-view Image Geo-localization

yanghongji2007/saig 3 Feb 2023

To address the above three challenges for cross-view image matching, we propose a new backbone network, named Simple Attention-based Image Geo-localization network (SAIG).

Joint Representation Learning and Keypoint Detection for Cross-view Geo-localization

AggMan96/RK-Net IEEE Transactions on Image Processing (TIP) 2022

Inspired by the human visual system for mining local patterns, we propose a new framework called RK-Net to jointly learn the discriminative Representation and detect salient Keypoints with a single Network.

PDC-Net+: Enhanced Probabilistic Dense Correspondence Network

PruneTruong/DenseMatching 28 Sep 2021

In order to apply dense methods to real-world applications, such as pose estimation, image manipulation, or 3D reconstruction, it is therefore crucial to estimate the confidence of the predicted matches.
