When you know what form factor can solve your high-speed application, it's time to figure out what intensity control gets the brightness you need: a regular light on overdrive or a dedicated strobe light? Here's how you do it: 1️⃣ Set the camera to the ideal exposure time 2️⃣ Overdrive the standard light at max. intensity (with respect to duty cycle and max. intensity rating) 3️⃣ Set the strobe time of the light to 85~90% shorter than the exposure time 4️⃣ If the image is not bright enough, repeat Step 3 but step up to a dedicated strobe light (a strobe light will likely work if an overdriven light does not) 5️⃣ IF the intensity is still not bright enough, consider slowing the inspection speed or consulting a lighting manufacturer about a custom strobe light 6️⃣ Confirm the initial solution works with the new intensity control method and adjust as needed You might need to make some adjustments to the initial solution after stepping up to either the overdrive or strobe light. Possible adjustments can include: 👉 Alternative strobe-only model (since there are fewer strobe lights available off-the-shelf 👉 Light angle and/or LWD 👉 Add or remove optical accessories We recently released a hypothetical case study walking through how to solve a high-speed application.

Every application evaluation we do for a customer culminates in an evaluation report that looks like this: We include all the information to help prove out lighting concepts for a vision system like - Light models tested (including the ones that got good enough, ok, and not so great results) - The overall setup (including measurements of where the light was positioned relative to the sample and camera) - Component recommendations (if the ones specified by the customer were insufficient for the application) Get an evaluation performed for your application.

How does the lighting evaluation process change for high-speed applications? Short answer: Not much. Longer answer: But there's a few tips we have for making it easier. ➤ Exposure time is really important. If you/your customer doesn't have an exposure time determined, we have the formula for calculating it in the carousel below. ➤ Start the lighting evaluation as if it's not a high-speed application. It's easier to test all standard lights on continuous mode vs. setting the current rating and strobe time for each strobe light. There are also more lights available off-the-shelf to overdrive compared to strobe-only lights. ➤ Make sure that the solution you found when testing at a slower exposure time works when you switch to a light on overdrive/strobe-only light. You might need to make some adjustments in angle, LWD, etc. We recently released a hypothetical case study walking through how to solve a high-speed application. 📖 Read it here: https://lnkd.in/evxkrKMm #machinevision #LEDlighting #industrialautomation #manufacturingautomation #foodandbeverage #beerbottle

Theory of Light and Color Ch 7 continues our talk on the different radiant quantities and luminous quantities. We also introduce CCS's unique approach to evaluating brightness in machine vision using sensor-metric quantities tailored to the "eye" of a machine. 🔗 to article: https://lnkd.in/eMnmq7Te #TheoryofLightandColor #machinevision #LEDlighting

While a high-speed application is mostly the same as solving a standard application, there are a few extra steps to finding the light setup that gets enough intensity within your exposure time AND accurate results. Lindsey Sullivan helped create a hypothetical application for beer bottles to walk you through a lighting expert's process for evaluating lighting solutions for high-speed inspections.

Don't be remembered for "failed" machine vision projects. The ones that customers shut down and make them swear off trying to automate again. The projects that collect dust in a corner of the facility before getting scrapped for parts because the vision system didn't work after it was built. And too much time was spent trying to figure out the cause. Too often, the cause of machine vision failure is incorrect lighting. Illumination will never NOT be important for challenging vision applications. That's why lighting has to be considered from the beginning of an application, not after things have gone wrong. Find your "lighting guy" who will find you the best solution, so you can build a system that actually does what your customer expects it to do. #machinevision #LEDlighting #industrialautomation

The "brightness" you experience of light reflecting off your desk differs from that of a TV screen or traffic light. Our new chapter of Theory of Light and Color delves deeper into this: https://lnkd.in/e37Hjk7c 🌟 Key Highlights: - Variations in Brightness: Discover how brightness isn't just about how much light hits our eyes but also involves factors like direction, angle, and area. - Spectroscopic vs. Geometric Conditions: Learn how brightness is measured differently under these various factors. - Machine Vision Applications: Understand how we use these principles to manipulate brightness in machine vision. Whether you're a professional in the field or simply curious about the science behind light, this article gives insight into how we perceive and measure brightness in different contexts. #TheoryofLightandColor #machinevision #LEDlighting

If you asked us if we ever did an application for detecting the presence/absence of the right flavor packet for instant ramen and bought the exact light we used without testing... ...You run a high risk of setting yourself up for failure. Say in your application, the packets come at a 45-degree angle some or all of the time. The solution we recommended for the previous application causes glare that makes the packet completely unreadable. Now you wasted resources buying the wrong solution, and you have way less time to find an actual solution. Assuming a light used to solve an application similar to your own will work for you is one of the biggest misconceptions that trip up engineers in machine vision lighting. We cover this and more in a recent article with Control Design magazine. Read it in full: https://lnkd.in/e_56AMEW #machinevision #LEDlighting #industrialautomation
