# AgriField3D: A Curated 3D Point Cloud Dataset of Field-Grown Plants From A Maize Diversity Panel

## Dataset Structure

The dataset consists of two compressed `.zip` files, which contain the 3D point cloud data:

2. **Extract the files**:
   ```bash
   unzip FielGrwon_ZeaMays_RawPCD_100k.zip
   unzip FielGrwon_ZeaMays_RawPCD_50k.zip
   unzip FielGrwon_ZeaMays_RawPCD_10k.zip
   unzip FielGrwon_ZeaMays_SegmentedPCD_100k.zip
   unzip FielGrwon_ZeaMays_SegmentedPCD_50k.zip
   unzip FielGrwon_ZeaMays_SegmentedPCD_10k.zip
   ```

3. Use the extracted `.ply` files in tools like:
   - MeshLab
   - CloudCompare
   - Python libraries such as `open3d` or `trimesh`.

### Example Code to Visualize the `.ply` Files in Python
```python
import open3d as o3d

# Load and visualize a PLY file from the dataset
pcd = o3d.io.read_point_cloud("FielGrwon_ZeaMays_RawPCD_100k/0001.ply")
o3d.visualization.draw_geometries([pcd])
```
