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.

News

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://arxiv.org/pdf/2204.08381

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.

21 August 2020 The transfer learning code for Oxford and Paris is at Here.

27 July 2020 The meta data of 1652 buildings, such as latitude and longitude, are now available at Google Driver. (You could use Google Earth Pro to open the kml file or use vim to check the value).
We also provide the spiral flight tour file at Google Driver. (You could open the kml file via Google Earth Pro to enable the flight camera).

26 July 2020 The paper is accepted by ACM Multimedia 2020.

12 July 2020 I made the baseline of triplet loss (with soft margin) on University-1652 public available at Here.

12 March 2020 I add the state-of-the-art page for geo-localization and tutorial, which will be updated soon.

Code Features

Now we have supported:

  • Float16 to save GPU memory based on apex
  • Multiple Query Evaluation
  • Re-Ranking
  • Random Erasing
  • ResNet/VGG-16
  • Visualize Training Curves
  • Visualize Ranking Result
  • Linear Warm-up

Prerequisites

  • Python 3.6
  • GPU Memory >= 8G
  • Numpy > 1.12.1
  • Pytorch 0.3+
  • [Optional] apex (for float16)

Getting started

Installation

git clone https://github.com/pytorch/vision
cd vision
python setup.py install
  • [Optinal] You may skip it. Install apex from the source
git clone https://github.com/NVIDIA/apex.git
cd apex
python setup.py install --cuda_ext --cpp_ext

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

python prepare_cvusa.py
python train_cvusa.py --name usa_vgg_noshare_warm5_lr2 --warm 5 --lr 0.02 --use_vgg16 --h 256 --w 256  --fp16 --batchsize 16;
python test_cvusa.py  --name usa_vgg_noshare_warm5_lr2 

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.

Trained Model

You could download the trained model at GoogleDrive or OneDrive. After download, please put model folders under ./model/.
