Machine Vision
Machine vision is the use of cameras, lighting, and image-processing software to let machines inspect, measure, guide, and identify objects automatically. In industry it performs tasks such as defect detection, dimensional checking, barcode reading, and robot guidance at high speed and consistency.
A machine vision system captures images with industrial cameras under controlled lighting, then processes them to extract features, measurements, or pass/fail decisions, often feeding results to a PLC or reject mechanism. Applications include verifying assembly, checking print quality, and positioning parts for robots. Machine vision matters because it provides objective, repeatable, non-contact inspection at production speeds, catching defects and ensuring quality far more consistently than manual visual checking can achieve.
