Dataset Formats

This dataset is provided in three formats to support different use cases:

1. Raw Format (raw/)

Preserves all original Omniverse data:

• RGB images (PNG)
• 2D bounding boxes (NumPy .npy)
• Class labels (JSON)
• 3D primitive paths (JSON)
• Instance segmentation masks (PNG)
• Instance ID mappings (JSON)
• Depth/distance maps (NumPy .npy)

Use for: Multi-task learning, depth estimation, 3D tasks, research

2. YOLO Format (yolo/)

Standard YOLO v5/v8 format:

• Images in images/train/, images/val/, images/test/
• Labels in labels/train/, labels/val/, labels/test/
• Each label file contains: class_id x_center y_center width height (normalized 0-1)

Use for: Object detection with YOLO models (Ultralytics, Darknet)

3. COCO Format (coco/)

COCO JSON format:

• Images in images/train/, images/val/, images/test/
• Annotations in annotations/instances_{train,val,test}.json

Use for: Object detection/segmentation with detectron2, MMDetection, etc.

Usage Examples

YOLO (Ultralytics)

from ultralytics import YOLO

# Train a model
model = YOLO('yolov8n.pt')
model.train(data='warehouse_detection_dataset/data.yaml', epochs=100)

# Validate
metrics = model.val()

# Predict
results = model('path/to/image.jpg')

COCO (detectron2)

from detectron2.data import DatasetCatalog, MetadataCatalog
from detectron2.data.datasets import load_coco_json

# Register dataset
DatasetCatalog.register(
    "warehouse_train",
    lambda: load_coco_json(
        "warehouse_detection_dataset/coco/annotations/instances_train.json",
        "warehouse_detection_dataset/coco/images/train"
    )
)

# Train your model
# ... (standard detectron2 training code)

Raw Format (Custom)

import numpy as np
import json
from PIL import Image

# Load image
img = Image.open('raw/train/images/warehouse_000001.png')

# Load bounding boxes
bboxes = np.load('raw/train/annotations/warehouse_000001_bbox.npy')

# Load labels
with open('raw/train/annotations/warehouse_000001_labels.json') as f:
    labels = json.load(f)

# Load segmentation mask
seg_mask = Image.open('raw/train/segmentation/warehouse_000001_seg.png')

# Load depth map
depth = np.load('raw/train/depth/warehouse_000001_depth.npy')
