I am part of an FRC team, and I want to understand how to get the coordinates from retroreflective pieces/strips. We are using a green headlight, situated directly on the camera lens to get maximum saturation.
Today, I was able to successfully find the retroreflective tape using Canny. Now, I want to make it find the closed boxes, because the goals show as a closed box. I then want to do some thresholding to make sure it is at least a little green.
The problem is: I am stuck because I have no idea of what to use to highlight the polygons. After that, I don't know how to make sure it is green.
I'm sorry for this newbie-like post, but I am very stuck and rapidly running towards the deadline!
