# CoInfra: A Large-Scale Cooperative Infrastructure Perception System and Dataset in Adverse Weather

**CoInfra** is a real-world, large-scale cooperative perception system and dataset designed to support research in multi-agent perception, especially under **adverse weather conditions** (snow, rain, freezing rain). It features 14 synchronized infrastructure nodes, each with a LiDAR and dual cameras, deployed across a shared region for full-scene coverage.

## Download Instructions
**Use the huggingface_hub CLI or library**
```bash
pip install huggingface_hub
```

Create a python script in "CoInfra" folder, and run it:

```python
from huggingface_hub import snapshot_download

path = snapshot_download(
    repo_id="MinghaoNing/CoInfra",
    repo_type="dataset",
    local_dir=".",                # <-- download into current folder
    local_dir_use_symlinks=False  # <-- ensure actual files are copied
)

print("Downloaded to:", path)
```

This will download the full dataset repo (all files) to a local folder.

## Extraction Instructions
The archives are compressed using `zstd` for fast decompression. To extract the dataset, you need to have `zstd` installed. You can install it via package managers like `apt`, `brew`. 

**To extract an archive, use the following command:**
```bash
tar --use-compress-program=zstd -xf [archive_file.tar.zst]
```

**To extract all archives in a directory, you can use:**
```bash
for archive in *.tar.zst; do
    echo "Extracting $archive..."
    tar --use-compress-program=zstd -xf "$archive"
done
```
