Re: Is it possible for GRIP to find the boulder?

GRIP is based on OpenCV. I'm not sure how many functions it exposes. There are LabVIEW examples for 2014 and perhaps other years that show an approach to do this using NIVision. Generally, color alone will not be a good enough predictor. I'd hope that your code doesn't rely solely on color for targets either.

Don't forget to think about your camera mounting if you are trying to identify a ball. A camera mounted low will see lots of background that intersects with the ball. A camera mounted a bit higher and aims down will see more carpet around the ball. It will also see less shadow. Also, if a silver ball is in a corner with a shiny diamond-plate wall on one side and a reflective lexan wall on the other, you probably shouldn't expect a camera to be your best sensor option.
