Custom dataset of YOUR object ($249)

Need data of YOUR object? Custom synthetic dataset, $249 USD -> order on Polar

• What you get: 2,000 labelled photoreal synthetic images (640x640 JPEG) of your own object or scenario (product, part, tool, drone, package, defect...), up to 3 classes, YOLO bounding boxes + data.yaml, train/val/test split, quality report
• Licence: commercial use allowed
• Price: $249 USD one-time; one round of adjustments included
• Delivery: typically 3-5 business days after we receive your reference photos + rough dimensions
• Optional sim-to-real test: send ~200 of your own labelled real images and we report how much the synthetic data improves a detector on them
• Refund: full refund if we cannot deliver your request (14-day refund policy)
• Limits: only objects you own or are allowed to use; no weapons or anything meant to harm people; no copied third-party 3D assets

Summary

Synthetic photos of glass jars (5 jar types) with YOLO bounding boxes and per-object attributes (tint, lid, contents, fill level), for retail shelf, kitchen robotics and inventory models; the paid full edition can be used commercially.

• Best for: jar detection / attribute pre-training, robot grasping research, inventory demos
• Not for: recognising specific commercial brands or labels

Quick start

# pip install huggingface_hub ultralytics

Price & licence

• Full edition: $25 USD. One-time payment, instant download after checkout: https://buy.polar.sh/polar_cl_7qTni7LxfUbHsqVdcX93IKNhEZa9ieFHwHxWq36r8ej (also on Gumroad: https://quailcraft1.gumroad.com/l/synthetic-glass-jars)
• QuailModel Commercial Dataset Licence (SPDX: LicenseRef-QuailModel-Commercial): you may train, evaluate and ship models, including in commercial products. You may not resell or redistribute the dataset itself.
• Free sample (this page): CC BY-NC-SA 4.0 - free for non-commercial use.

Limitations

• Synthetic renders (Cycles path tracing): fine-tune on real photos before production.
• Five original jar families only - not brand-specific products.

This free sample: 300 images (train 237 / val 34 / test 29). Full commercial edition: 5,000 images 640x640 (train 3,975 / val 529 / test 496) with YOLO labels + attribute JSON (zip 98.4 MB). Fully synthetic data; summary, facts, validation and limitations are in the block above.

• Image size: 640x640 JPEG. Labels: YOLO txt, classes: 0 = mason_jar, 1 = apothecary_jar, 2 = spice_jar, 3 = hex_jar, 4 = squat_jam_jar. Images with an empty label file are true negatives (24 of 300).
• Boxes per class: mason_jar 182, apothecary_jar 194, spice_jar 186, hex_jar 203, squat_jam_jar 190
• meta/ holds per-object attribute JSON (class, box, visibility and module-specific attributes).
• data.yaml included - train directly with Ultralytics YOLO.
• Box size distribution (fraction of image width): median 0.074, 4% of boxes are smaller than 16 px.

How it was made

Original 3D models, procedurally generated and rendered with a physically based renderer under real-world lighting, with realistic camera effects. Labels are computed exactly from the 3D scene (no hand labelling).
