Machine Vision Techniques: Practical Ways to Improve Efficiency in Machine Vision Inspection

machine vision efficiencyMachine vision efficiency is at the core of production efficiency. The speed of manufacturing is often dependent upon the speed of machine vision inspection. Creating efficiencies in machine vision can have wide reaching benefits on manufacturing productivity.

Are you doing all you can to make machine vision as accurate and efficient as possible? The following are a few practical ways to improve the efficiency of your machine vision systems.

4 Practical Tips for Machine Vision Efficiency

The following tips are fundamental, but quick, fixes to improve machine vision efficiency if you’re inspection processes are slowing down or impacting production.

1. Lighting Techniques

Is your lighting technique maximizing contrast for the area of inspection? Between backlighting, bright field lighting, grazing, low angle linear array, and dark field lighting, there are often several different ways to illuminate the same application. The technique with the highest contrast will help improve the accuracy of image capture.

2. Light Wavelength and Frequency

Some parts, such as metallic products, may arrive at your facility and be inspected with a light coating of oil on them from storage. This will create noise in your images. Adjusting the frequency and wavelength of light you’re using can help combat this type of noise introduced into the inspection environment.

3. Trigger Range Function

Sometimes, the broader industrial environment will create electrical noise and cause false triggering of your inspection system – which could have numerous devastating consequences on production, such as the software concluding that passable objects are failing inspection. Implementing a trigger range function, controlling for the length of the trigger signal, to maintain the integrity of machine vision inspection systems.

4. Filtering

Industrial environments often introduce background and/or overhead lighting noise into the inspection area. Many times, this can be completely filtered out with the correct wavelength of lens filter, improving the accuracy and quality of image capture.

Machine vision works best in consistent, undisturbed environments, but this is rarely the case in an industrial setting. The tips mentioned above are some quick ways to improve the efficiency of machine vision inspection, which improves the efficiency of overall production.
