Knowledge

Practical knowledge for a testable vision solution

A vision system starts with the required process change. This may be less manual inspection, fewer rejects, a shorter cycle or fewer operator interventions. Use this knowledge base to define the technical decision and prepare a representative trial.

Requirements and acceptance

Test with the variation found in production

Practical acceptance criteria

  • Define the conforming and non-conforming products the system must distinguish.
  • Include variation in position, surface, colour, contamination and ambient light in the trial set.
  • Measure false rejects, missed defects, cycle time and operator interventions separately.
  • Test recipe changes, stops, restarts and recovery after a failed measurement or pick.

Inputs for the business case

Use data from your own process: product volume per shift, labour minutes, current rejects and rework, downtime, changeover time, maintenance and integration cost. Compare these inputs with the measured trial results. This keeps the payback calculation traceable.

Guides and practical tests

Use the knowledge base in four practical steps

1. Define the process question

Specify what must be seen, measured or picked and how an error affects production.

2. Collect parts

Include conforming and non-conforming products and normal variation from different shifts or batches.

3. Test production variation

Vary position, speed, surface, ambient light and contamination within realistic limits.

4. Define acceptance

Record edge cases, cycle time, false rejects, missed defects and required operator interventions.
