About Machine Vision
While human inspectors working on assembly lines visually inspect parts to judge the quality of workmanship, machine vision systems use cameras and image processing software to perform similar inspections. Machine Vision inspection plays an important role in achieving 100% quality control in manufacturing, reducing costs and ensuring a high level of customer satisfaction.
Machine vision system inspection consists of narrowly defined tasks such as counting objects on a conveyor, reading serial numbers, and searching for surface defects. Manufacturers often prefer machine vision systems for visual inspections that require high speed, high magnification, around-the-clock operation, and/or repeatability of measurements.

For example, semiconductor fabrication depends greatly on vision inspection technology, without which yields for computer chips would be significantly reduced. Machine vision systems inspect silicon wafers, processor chips, and sub-components such as resistors and capacitors at high speeds with precision and accuracy.
