This repository contains the dataset link and the code for our paper University-1652: A Multi-view Multi-source Benchmark for Drone-based Geo-localization, ACM Multimedia 2020. The offical paper link is at https://dl.acm.org/doi/10.1145/3394171.3413896. We collect 1652 buildings of 72 universities around the world. Thank you for your kindly attention.

Task 1: Drone-view target localization. (Drone -> Satellite) Given one drone-view image or video, the task aims to find the most similar satellite-view image to localize the target building in the satellite view.

Task 2: Drone navigation. (Satellite -> Drone) Given one satellite-view image, the drone intends to find the most relevant place (drone-view images) that it has passed by. According to its flight history, the drone could be navigated back to the target place.

1. IEEE ITSC Special Session

We host a special session on IEEE Intelligent Transportation Systems Conference (ITSC), covering the object re-identification & point cloud topic. The paper ddl is by May 15, 2023 and the paper notification is at June 30, 2023. Please select the session code ``w7r4a'' during submission. More details can be found at Special Session Website.

2. Remote Sensing Special Issue

We raise a special issue on Remote Sensing (IF=5.3) from now to ~~16 June 2023~~ 16 Dec 2023. You are welcomed to submit your manuscript at (https://www.mdpi.com/journal/remotesensing/special_issues/EMPK490239), but you need to keep open-source fee in mind.

3. ACM Multimedia Workshop

We are holding the workshop at ACM Multimedia 2023 on Aerial-view Imaging. Call for papers 中文介绍

4. Coda Lab Challenge

We also provide a challenging cross-view geo-localization dataset, called University160k, and the workshop audience may consider to participate the competition. The motivation is to simulate the real- world geo-localization scenario that we usually face an extremely large satellite-view pool. In particular, University160k extends the current University-1652 dataset with extra 167,486 satellite- view gallery distractors. We have release University160k on the challenge page, and made a public leader board. (More details are at https://codalab.lisn.upsaclay.fr/competitions/12672)

2 Jul 2024 Text-guided Geo-localization is accepted by ECCV 2024 (https://arxiv.org/pdf/2311.12751).

26 Jan 2023 1652 Building Name List is at Here.

10 Jul 2022 Rainy？Night？Foggy？ Snow？ You may check our new paper "Multiple-environment Self-adaptive Network for Aerial-view Geo-localization" at https://github.com/wtyhub/MuseNet (accepted by Pattern Recognition'24)

1 Dec 2021 Fix the issue due to the latest torchvision, which do not allow the empty subfolder. Note that some buildings do not have google images.

3 March 2021 GeM Pooling is added. You may use it by --pool gem.

21 January 2021 The GPU-Re-Ranking, a GNN-based real-time post-processing code, is at Here.

Dataset & Preparation

Download [University-1652] upon request. You may use the request template.

Or download CVUSA / CVACT.

For CVUSA, I follow the training/test split in (https://github.com/Liumouliu/OriCNN).

Train & Evaluation

Train & Evaluation University-1652

python train.py --name three_view_long_share_d0.75_256_s1_google  --extra --views 3  --droprate 0.75  --share  --stride 1 --h 256  --w 256 --fp16; 
python test.py --name three_view_long_share_d0.75_256_s1_google

Default setting: Drone -> Satellite If you want to try other evaluation setting, you may change these lines at: https://github.com/layumi/University1652-Baseline/blob/master/test.py#L217-L225

Ablation Study only Satellite & Drone

python train_no_street.py --name two_view_long_no_street_share_d0.75_256_s1  --share --views 3  --droprate 0.75  --stride 1 --h 256  --w 256  --fp16; 
python test.py --name two_view_long_no_street_share_d0.75_256_s1

Set three views but set the weight of loss on street images to zero.

Train & Evaluation CVUSA

Show the retrieved Top-10 result

python test.py --name three_view_long_share_d0.75_256_s1_google # after test
python demo.py --query_index 0 # which image you want to query in the query set

It will save an image named `show.png' containig top-10 retrieval results in the folder.
