Conda Environment Setup

Our repository requires a conda environment. Relevant packages are listed in env.yml. Run the following command to setup the conda environment.

conda env create -f env.yml

Training

You can find the training scripts and evaluation scripts in scripts folder. The scripts is for slurm system to submit sbatch job. If you want to run bash command, change the suffix from sbatch to sh and run with bash.

TGM training

1. To train Thermal Generate Module (TGM), use one of the following scripts:

./scripts/train_bing_thermal_translation_100.sbatch # Best choice
./scripts/train_bing_thermal_translation_10.sbatch
./scripts/train_bing_thermal_translation_100_noncontrast.sbatch
./scripts/train_bing_thermal_translation_10_noncontrast.sbatch

After training TGM, find your model folder in ./logs/default/satellite_0_thermalmapping135-datetime
The satellite_0_thermalmapping135-datetime is your TGM_model_folder_name.

2. To generate thermal images from extended_database.h5, run one of the following scripts:

./eval_satellite_translation.sh   TGM_model_folder_name # Best choice
./eval_satellite_translation_nocontrast.sh   TGM_model_folder_name

After running this scripts, you can find a file train_queries.h5 in ./test/default/model_folder_name/satellite_0_thermalmapping135-datetime
Rename it to extended_queries.h5 and move it to ./datasets/satellite_0_thermalmapping135.

3. Rename the dataset folder to one of the following:

./datasets/satellite_0_thermalmapping_135/                  #./scripts/train_bing_thermal_translation_10.sbatch
./datasets/satellite_0_thermalmapping_135_100/              #./scripts/train_bing_thermal_translation_100.sbatch
./datasets/satellite_0_thermalmapping_135_nocontrast/       #./scripts/train_bing_thermal_translation_10_nocontrast.sbatch
./datasets/satellite_0_thermalmapping_135_100_nocontrast/    #./scripts/train_bing_thermal_translation_100_nocontrast.sbatch

The dataset name depends on the training script you use, which is listed on the right of each dataset name. This is to avoid confusion about which TGM setting is used to generate.

SGM training

To train Satellite-thermal Geo-localization Module (SGM), use one of the scripts in ./scripts per name, for example:

./scripts/train_bing_thermal_partial_conv4096_bn_lr_wd_DANN_after_ld_dp_contrast_extended_100.sbatch # Best choice

After training SGM, find your model folder in ./logs/default/satellite_0_thermalmapping135-datetime-uuid
The satellite_0_thermalmapping135-datetime-uuid is your SGM_model_folder_name.

Evaluation

To evaluate SGM, use one of the following scripts:

./scripts/eval.sbatch   SGM_model_folder_name   backbone_name
./scripts/eval_nocontrast.sbatch   SGM_model_folder_name   backbone_name

Note that running evaluation scripts requires two arguments: SGM_model_folder_name and backbone_name. The typical backbone we use is resnet18conv4.

Find the test results in in ./test/default/model_folder_name/satellite_0_thermalmapping135-datetime. There will be two folders. This first reports R@1 and R@5. The second reports R_512@1, R_512@5 and L^512_2.
