It is impossible to overestimate the critical nature of keen and constant visual inspection in any production process. That’s why an advanced vision system is vital for any of today’s advanced production lines – as well as for “yesterday’s” older and more issue-prone lines. 

Vision guided robotics (VGR) is an automation technology well-recognized for enabling greater flexibility and higher productivity in a diverse set of manufacturing tasks over a wide range of industries.

Part 1 of this three-part series examined how to identify characteristics of the object and the background you can use to create contrast with the illumination source for your machine vision application. This second part looks at how you go about choosing a light source to take advantage of the characteristics that create contrast. 

Imaging lenses enable machine vision systems to inspect, sort, and measure objects for a variety of applications including manufacturing, robotics, autonomous (self-driving) vehicles, and more. 

The use of machine vision in industrial automation applications continues to increase as companies look for gains in productivity, efficiency and safety. Market forecasters estimate that the total market for machine vision will reach more than $18 billion by 2025, up from about $10 billion today. 

Several critical components need to come together to form a machine vision system. This includes the sensor (typically within a camera) that captures a picture for inspection, the processing hardware (a PC or vision appliance) and software algorithms to render and communicate the results. In addition, lighting, staging, and lenses are required to set up a machine vision system.

For the past few decades, consumers have rewarded companies that customize their products and services to individual tastes and needs.

You have probably heard, and perhaps experienced, that lighting is a big challenge in applying machine vision and a vital key to its successful application.
