At the Midwest regional, we had difficulty with getting constant targets from the Rectangular Target processing VI using a green light setting. We got more consistent results after expanding the values on the “margin” controls, but consistency on the field doesn’t seem reliable enough, even after calibrating.Is there a way to eliminate all color but green from the camera? I noticed that the targeting VI does all of it’s logic in HSL, and the only way I could think to eliminate all colors but green is to convert to RGB and take out the planes of R/B. Thanks in advance for any help!
What does your camera initialization look like in Begin.vi?
Are you setting your exposure, brightness and white balance or letting them run automatically?
Keeping only the green plane will be similar to looking at the world through green tinted glasses, and it will help to ignore purely red and blue objects. What does it do to a white object?
White minus red minus blue is … Green. So, you can no longer tell white and grays from green. Additionally, what about yellow, or Cyan?
At least in some implementations, HSV is a less expensive conversion than HSL, so you may want to compare their timings.
