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 images of 6 fruits with YOLO bounding boxes and ripeness labels (unripe / ripe / overripe), for agritech sorting, retail shelf monitoring and robotic picking; the paid full edition can be used commercially.

• Best for: fruit detection and ripeness pre-training, sorting-line prototypes
• Not for: food-safety or quality decisions without real-photo validation

Quick start

# pip install huggingface_hub ultralytics
from huggingface_hub import snapshot_download

Price & licence

• Full edition: $25 USD. One-time payment, instant download after checkout: https://buy.polar.sh/polar_cl_I15FSJ1fslvMqru1TMDXqoDTS1eIHgGL90lBK2RtCMN (also on Gumroad: https://quailcraft1.gumroad.com/l/synthetic-fruit-ripeness)
• 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

• Clean, semi-stylized renders - fine-tune on real photos for production.
• Ripeness is modelled through skin colour and blemishes only.

This free sample: 300 images (train 247 / val 31 / test 22). Full commercial edition: 5,000 images 640x640 (train 3,977 / val 520 / test 503) with YOLO labels + attribute JSON (zip 112.0 MB). Fully synthetic data; summary, facts, validation and limitations are in the block above.

split	images	boxes
train	247	1298
val	31	178
test	22	130

• Image size: 640x640 JPEG. Labels: YOLO txt, classes: 0 = apple, 1 = orange, 2 = lemon, 3 = banana, 4 = tomato, 5 = pear. Images with an empty label file are true negatives (3 of 300).
• Boxes per class: apple 259, orange 285, lemon 280, banana 205, tomato 280, pear 297
• 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 0.117, 0% 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).
