A Quick Look at Color Lighting and Filters for Vision Sensors
Manufacturers who use machine vision systems to inspect parts, guide robotic arms and sort packages confront the same reality known to every weekend shutterbug: It’s all about getting the light right.
The trouble is that a factory floor is a photographic minefield. Shops windows let in too much light at high noon but cast too many shadows when the second shift clocks in. Shiny parts reflect light back into the camera, spoiling the image.
The solution to these lighting quirks lies with machine vision filters, dispersed lighting, and many more lighting tactics that ensure machine vision systems produce the clear digital images that factory automation inspections requires.
