AI-TOD

Download

You need to download the following two parts (Part1: xView training set, Part2: part of AI-TOD) and use our end-to-end synthesis tool to generate the complete AI-TOD dataset. (Note the we have released the complete annotations of AI-TOD, you only need to generate images)

• xView training set. [Website]
• Part of AI-TOD. [OneDrive]
• E2E aitodtoolkit. [Folder]

A Guide on Generating AI-TOD

Step 1: Download the xView training set, AI-TOD without xview, and clone the aitodtoolkit.

git clone https://github.com/SaShukla090/AI-TOD_data_generation.git

Step 2: Organize the downloaded files in the following way.

├─aitod
│  ├─annotations ## put the downloaded annotations of AI-TOD_wo_xview (.json)
│  └─images ## unzip the downloaded AI-TOD_wo_xview image sets, put them (.png) in the corresponding folder
│      ├─test ## directly put the images in it without extra folder
│      ├─train 
│      ├─trainval 
│      └─val 
├─aitod_xview ## here are six files (.txt)
├─xview
│  ├─ori
│  │   └─train_images ## unzip the downloaded xView training set images, put them (.tif) here
│  └─xView_train.geojson ## the annotation file of xView training set
└─generate_aitod.py ## end-to-end tool

Step 3: Install required packages.

• Required environment (make the conda env using using 'data/aitod/AI-TOD/conda_env_aitod.yml' file)

conda env create -f conda_env_aitod.yml
conda activate aitod
pip install -r requirements.txt

• mmcv install mmcv==1.0 (don't isntall mmcv 2.0 version which is default)

pip install mmcv==1.0.0 -f https://download.openmmlab.com/mmcv/dist/cu118/torch2.0/index.html

Step 4: Run the E2E aitodtoolkit and get AI-TOD, it might take around an hour, then the full image sets of AI-TOD can be found in the aitod folder. And you can delete other files in other folders to avoid taking up too much space.

python generate_aitod_imgs.py

Evaluation

Training, Validation and Testing sets are both publicly available now. We report the COCO style performance in the original paper, you can use the cocoapi-aitod to evaluate the model performance.
