Things I build

From the notebook

Anonymized notes on how I tackle real machine-vision and inspection problems - the approaches I tried, what failed, and the lessons worth keeping.

• The inspection pyramid A defect travels through a long chain before it becomes a decision. The later you catch a problem, the more it costs.
• AOI lighting cookbook Lighting is often more important than the camera. Many inspection problems are actually lighting problems.
• Focus stacking in production High magnification destroys depth of field. Focus stacking is never purely an optical problem.
• Every sample lies Customers send their best and worst parts. The dangerous gap is everything in between.
