# Pyro-SDIS Subset Dataset

![Pyronear Logo](https://huggingface.co/datasets/pyronear/pyro-sdis/resolve/main/logo.png)


# Pyro-SDIS Subset

⚠️ **Warning: This is a pre-release version of the Pyro-SDIS dataset.**  
This subset is provided for early access and experimentation. Not all images are currently included, and there may still be annotation errors. The full release of the 2025 version of Pyro-SDIS (based on images collected in 2024) will be available in **January 2025**.

---

## About the Dataset

Pyro-SDIS is a dataset designed for wildfire smoke detection using AI models. It is developed in collaboration with the Fire and Rescue Services (SDIS) in France and the dedicated volunteers of the Pyronear association.

The images in this dataset come from Pyronear cameras installed with the support of our SDIS partners. These images have been carefully annotated by Pyronear volunteers, whose tireless efforts we deeply appreciate. 

We extend our heartfelt thanks to all Pyronear volunteers and our SDIS partners for their trust and support:

- **Force 06**
- **SDIS 07**
- **SDIS 12**
- **SDIS 77**

Additionally, we express our gratitude to the DINUM for their financial and strategic support through the AIC, Etalab, and the Legal Service. Special thanks also go to the Mission Stratégie Prospective (MSP) for their guidance and collaboration.

## About the Subset

The Pyro-SDIS Subset contains **37,526 images**, including:

- **31,215 images with smoke**
- **35,458 smoke instances**

This dataset is formatted to be compatible with the Ultralytics YOLO framework, enabling efficient training of object detection models.

---

Stay tuned for the full release in **January 2025**, which will include additional images and refined annotations. Thank you for your interest and support in advancing wildfire detection technologies!


## Dataset Overview

### Contents
The Pyro-SDIS Subset contains images and annotations for wildfire smoke detection. The dataset is structured with the following metadata for each image:

- **Image Path**: File path to the image.
- **Annotations**: YOLO-format bounding box annotations for smoke detection:
  - `class_id`: Class label (e.g., smoke).
  - `x_center`, `y_center`: Normalized center coordinates of the bounding box.
  - `width`, `height`: Normalized width and height of the bounding box.
- **Metadata**:
  - `partner`: Partner organization responsible for the camera (e.g., SDIS 07, Force 06).
  - `camera`: Camera identifier.
  - `date`: Date of image capture (formatted as `YYYY-MM-DDTHH-MM-SS`).
  - `image_name`: Original file name of the image.
- **Split**: Indicates whether the image belongs to the training or validation set (`train` or `val`).

### Example Record
Each record in the dataset contains the following structure:
```json
{
  "image": "./images/train/partner_camera_date.jpg",
  "annotations": "0 0.5 0.5 0.1 0.2",
  "split": "train",
  "image_name": "partner_camera_date.jpg",
  "partner": "partner",
  "camera": "camera",
  "date": "YYYY-MM-DDTHH-MM-SS"
}
```

Let me know if you’d like further refinements or if you want me to include specific numbers/statistics for the dataset.

### Splits
The dataset is divided into:
- **Training split**: Used for training the model.
- **Validation split**: Used to evaluate model performance.



## Exporting the Dataset for Ultralytics Training

To train a YOLO model using the Ultralytics framework, the dataset must be structured as follows:
- **Images**: Stored in `images/train/` and `images/val/` directories.
- **Annotations**: Stored in YOLO-compatible format in `labels/train/` and `labels/val/` directories.

### Steps to Export the Dataset

1. **Install Required Libraries**:
   ```bash
   pip install datasets ultralytics
   ```

2. **Define Paths**:
   Set up the directory structure for the Ultralytics dataset:
   ```python
   import os
   from datasets import load_dataset

   # Define paths
   REPO_ID = "pyronear/pyro-sdis"
   OUTPUT_DIR = "./pyro-sdis"
   IMAGE_DIR = os.path.join(OUTPUT_DIR, "images")
   LABEL_DIR = IMAGE_DIR.replace("images", "labels")

   # Create the directory structure
   for split in ["train", "val"]:
       os.makedirs(os.path.join(IMAGE_DIR, split), exist_ok=True)
       os.makedirs(os.path.join(LABEL_DIR, split), exist_ok=True)

   # Load the dataset from the Hugging Face Hub
   dataset = load_dataset(REPO_ID)
   ```

3. **Export Dataset**:
   Use the following function to save the dataset in Ultralytics format:
   ```python
   def save_ultralytics_format(dataset_split, split):
       """
       Save a dataset split into the Ultralytics format.
       Args:
           dataset_split: The dataset split (e.g., dataset["train"])
           split: "train" or "val"
       """
       for example in dataset_split:
           # Save the image to the appropriate folder
           image = example["image"]  # PIL.Image.Image
           image_name = example["image_name"]  # Original file name
           output_image_path = os.path.join(IMAGE_DIR, split, image_name)

           # Save the image object to disk
           image.save(output_image_path)

           # Save label
           annotations = example["annotations"]
           label_name = image_name.replace(".jpg", ".txt").replace(".png", ".txt")
           output_label_path = os.path.join(LABEL_DIR, split, label_name)
           
           with open(output_label_path, "w") as label_file:
               label_file.write(annotations)

   # Save train and validation splits
   save_ultralytics_format(dataset["train"], "train")
   save_ultralytics_format(dataset["val"], "val")

   print("Dataset exported to Ultralytics format.")
   ```

4. **Directory Structure**:
   After running the script, the dataset will have the following structure:
   ```
   pyro-sdis/
   ├── images/
   │   ├── train/
   │   ├── val/
   ├── labels/
   │   ├── train/
   │   ├── val/
   ```

### Training with Ultralytics YOLO

1. **Download the `data.yaml` File**:
   Use the following code to download the configuration file:
   ```python
   from huggingface_hub import hf_hub_download

   yaml_path = hf_hub_download(repo_id="pyronear/pyro-sdis", filename="data.yaml")
   print(f"data.yaml downloaded to: {yaml_path}")
   ```

2. **Train the Model**:
   Install the Ultralytics YOLO framework and train the model:
   ```bash
   pip install ultralytics
   yolo task=detect mode=train data=data.yaml model=yolov8n.pt epochs=50 imgsz=640
   ```
