Yes, maybe. Keep in mind that the number of pixels will change as you keep a fixed distance from the green light, but rotate around it. Hmmm... Given that you kinda know how far away you are from the green light using the tilt angle, I wonder if you could then use the blob size to determine the angle.
Anyway, a better way might be to determine the height of the blob using y1 and y2 because the height won't vary much.
