DATA COLLECTION

Data collection services

Fill the gaps in your data.Start with a collection pilot.

Plan collection around missing scenarios and data types, and validate the approach with a pilot. Collect images, video, speech, text, 3D and multimodal data with source records and file indexes.

TASK-BASED SOURCES & COVERAGE

YOUR STARTING POINTIf you already have some data, first identify coverage gaps. You may not need to collect everything again.

COLLECTION SCENARIOS

Choose the data. Define the first collection batch.

Review coverage, collection conditions and checks for each data type. Agree source permissions before work begins.

IMAGE
Product capture: organize images by subject, viewpoint and lighting.
Product capture: organize images by subject, viewpoint and lighting.

IMAGE

Match image coverage to real tasks.

Coverage
Plan subjects, backgrounds, viewpoints and lighting; record sources and capture conditions.
Collection brief
Agree on resolution, clarity, source permissions, deduplication and class distribution.
Quality checks
Sharpness, exposure, duplicates, missing files and class coverage.

COLLECTION PLAN

Road-video collection: a pilot plan.

This road-perception project shows how to break down coverage targets. Other data types use the same dimensions–volume–checks approach with task-specific units.

COL-001 · Initial pilot plan

PILOT PLAN
COL-001 · Initial pilot plan
Scene combinationPlanned volumeReview focus
Urban road · daytime60 clipsParticipants and junction coverage
Urban road · nighttime30 clipsLow-light usability and exposure
Suburban road · daytime30 clipsDistant objects and varied backgrounds

120 clips total · 20 seconds each · Three scene groups

Review target volumes by scene group and use the pilot to confirm routes, equipment settings and recollection criteria.

Data requirements

  • Match every clip to a batch-index record
  • Record scene tags, timing and equipment references
  • Confirm naming, encoding and resolution in the pilot

Collection quality checks

  • Check decoding and clip completeness
  • Review duplicates, scene tags and coverage
  • Log failed checks and the recollection approach

INPUTS & DELIVERABLES

Clear requirements. Defined deliverables.

From files to text entries, recording logs to pair indexes, define delivery units and structure for the task. The downloadable plan illustrates road-video coverage.

Prepare for the first discussion

  • Model task and intended use
  • Scene dimensions, estimated volume and exclusions
  • Output preferences, equipment and timing constraints
  • Source permissions, access and data-handling needs

Deliverables agreed for your project

  • Collection files organized by batch
  • Indexes, scene tags and association records
  • Collection guidelines and equipment / calibration references
  • Coverage checks, exception records and version manifests

PROCESS & QUALITY

Use a pilot to turn requirements into instructions.

Each stage produces a record you can check. Agree volumes, schedules, acceptance criteria and responsibilities for your project.

FAQ

Before collection begins

01Do we need to recollect data we already have?

No. Review the coverage and usability of existing data first, then plan collection for the gaps. Reuse depends on source permissions and task requirements.

02Can we specify equipment, regions, languages or scenarios?

Yes, as requirements for assessment. Feasibility depends on equipment, site conditions, source permissions and project arrangements, and is checked during the pilot.

03How are source permissions and participation agreed?

Define intended use, participation, permissions and retention before collection. Sources with unclear conditions remain pending until those conditions are resolved.

START WITH THE SCENE

Define the first batch around your use case.

Share the model task, scene scope and estimated volume to identify what the pilot should validate.
