Are You Using A Camera To Align Their Shooter?

[GuyM142]

We use vision in order to align to the goal, we found out that the rate in which we get new measurement from the vision processing was too low to work properly with PID so we decided to use one image to calculate how much degrees to turn and then used the gyro to reach that angle. After settling down we take another image just to make sure the robot is on target.

We used GRIP to create a python algorithm which we use with OpenCV.
The frame rate was too slow for us as well, so we are taking one shot of the target, and use Encoders to turn the robot the calculated angle for the target with PID.
Later we double check that it is indeed aligned and that's it.
Takes us less than a second to align properly.

The big thing I want to emphasize with your robot if you are using vision is the closer you are to the target the less disruptive light can be in the way and the more accurate vision can be.

We didn't notice a difference between vision when we were close vs far at either of our two regionals. With correct camera exposure settings and tuned vision filtering, you can completely eliminate overhead lighting and tower LEDs from your image.
