Optimizing Lighting for AI Vision: How to Get Reliable Defect Detection

Lighting variability is one of the most common reasons AI inspection fails. Learn how to get it right.

Why Lighting Matters in AI Vision

Lighting variability is one of the most common—and most overlooked—reasons AI inspection fails. Glare, shadows, and inconsistent illumination confuse models and lead to false alarms.

Common issues:

  • Overexposure erases surface features.
  • Underexposure increases noise.
  • Lighting shifts cause inconsistent model outputs.
  • Shiny parts produce glare hotspots.

How Overview.ai Solves Lighting Challenges

OV10i

Built-in LED ring creates uniform illumination—no lighting expertise needed.

OV20i

Supports customizable external lighting to eliminate glare on reflective parts.

OV80i

Supports external strobe lighting for ultra-high sensitivity on micro-defects and OCR tasks.

💡 Pro Tip: You can preview images live with our browser-based interface, ensuring correct exposure and illumination before you train your model.

Lighting Best Practices

  • 1
    Use diffuse lighting to reduce glare.
  • 2
    Match color temperature to material color.
  • 3
    Shield from ambient light.
  • 4
    Keep lighting fixed after model training.
