Task: Implement OpenCV in autonomous

Last year, we had some experience with OpenCV to press the beacons, and this year we decided to do the same. We use OpenCV to find the color we are looking for on the beacon in conjunction with Vuforia. First, it detects the search pattern in the view with vuforia, then isolates that area and finds the side of the beacon with the correct color. Our code is based off of FTC team 3491, Fixit.

In a previous post, we talked about OpenCV and Vuforia research, as well as how we plan to use it in the robot game. And now, I am happy to say, we have implemented it partially in our autonomous. We can now figure out what side a specified color is on the beacon using our new phones, the Galaxy S5. (Side note - do not update them to Android Lolipop if you want to use OpenCV, it will not work.)

Reflections

In the future, we would like to implement OpenCV so that we can detect the color of a particle during autonomous and pick it up to shoot it. However, we probably don't have time to program it before Super Regionals.
