Lighting suggestions for OpenMV


I tried to use OpenMV to guide a robot arm to pick up a coin to learn robot and computer vision. I learned that a good and stable lighting is critical for color blob tracking.

I tried to add an 8 Neopixel ring which fit the lens perfectly. However, I learned that the ring adds too much light right under the camera and add almost no light 2 inches away.

I found professional lightings are huge panel or ring light with diffuser. I’m wondering do you have any recommendation for adding lighting for OpenMV?


Sorry, I don’t. Generally you want a diffuser however. Have you tried to make your own? Like a diffuser? You can make one by just putting some transparent material over the LED ring. Otherwise, make the light source come from not on the camera?
