SadiGroup is seeking experienced vendor teams for two upcoming AI data projects:

1. Autonomous driving: 3D LiDAR annotation

We need teams experienced in 3D bounding boxes for vehicles, pedestrians and other road users; object classification; continuous-frame ID tracking; and QA across complex road scenes. Experience with sparse point clouds, occlusion, box alignment and yaw accuracy is essential.

We need teams that can organize head-mounted binocular RGB recording with actual workers performing natural tasks in real workplaces. Priority environments include food service, retail, warehousing and logistics, automotive repair, and cleaning. Teams must be able to manage worker consent, recording quality and delivery across a diverse range of environments.

This opportunity is for established teams and vendors with relevant delivery experience.

To be considered, please send:

β€’ Redacted screenshots, samples or case studies from similar projects
β€’ Your available team size, locations and realistic weekly capacity

πŸ“£ Vendor partners wanted β€” 29,000 handwritten OCR images across 5 languages.

SadiGroup is sourcing collection partners for handwritten OCR datasets in Hindi, Thai, Italian, English and German. We're looking for teams with genuine native-speaker reach in each market.

VOLUMES
β€’ Hindi β€” 6,000 images
β€’ Thai β€” 5,000 images
β€’ English (US / UK / Canada etc.) β€” 12,000 images
β€’ German (Germany) β€” 3,000 images
β€’ Italian β€” 3,000 images

REQUIREMENTS
β€’ All handwriting must be produced by native speakers in-country.
β€’ Sourced online: images must come from local native-language sites. The source URL must be retained for every image and delivered in a matching data sheet β€” this is checked at acceptance.
β€’ Collected on-site: local authenticity must be evidenced. Accepted proof includes photos of the writing environment, EXIF metadata showing collection location, or equivalent.
β€’ 1080p or above, clear and legible handwriting. Clean backgrounds with minimal distracting text preferred.

RATES (per image, online / on-site)
β€’ Hindi β€” $0.03 / $0.05
β€’ Thai β€” $0.03 / $0.05
β€’ English β€” $0.03 / $0.05
β€’ German β€” $0.03 / $0.09
β€’ Italian β€” $0.04 / $0.09

3. Your turnaround time and a sample of 10–20 images.

πŸ“ New project β€” Tunisia & Libya | License Plate Image Collection

SadiGroup is sourcing at least 30,000 license plate images each from Tunisia and Libya for an upcoming computer vision dataset.

What we need:

β€’ Real-world captures only β€” vehicles on roads or in parking lots. No staged or stock images.

β€’ Fully legible plates β€” the entire plate readable to the human eye. Colour JPG, minimal compression artifacts.

β€’ Deliberately varied plate pixel width:
– Small / distant: under 60 px
– Medium: 60–90 px
– Large / close-up: over 90 px
Small, distant plates are the hardest recognition scenario and our biggest gap β€” that's where we need the most volume.

β€’ Scene diversity β€” daytime and nighttime, frontal and diagonal angles, different weather and lighting conditions.

β€’ Plate type coverage β€” all currently circulating styles and number ranges: standard civilian plates plus common variants (commercial, temporary, regional/provincial).

β€’ Sample diversity β€” different vehicles across different regions and cities. No repeated shots of the same few plates.

Rate: $0.03 per image.

If you'd like to take part, tell us:
1. Can you capture in person/offline, or would you be using web scraping?
2. How many images can you realistically deliver for Tunisia and for Libya respectively?
