2. Introduction Using one or more Video Cameras on a robot allows for target finding , direction to the target and distance to the target Cameras can use “Masking” an/or “Shape Recognition” 2

3. The FRC Topology 3

6. Can be used with servos to pan and tilt the camera to extend the visual bound

8. Pattern Recognition Viewing a target with a defined mathematical representation In the 2010 competition software was designed to find a “bull's-eye” located above the goal. This LabVIEW code shows how the video image is analyzed and the SubVI returns the target information including position, the score and from the minor to major radius ratio, the angle offset

9. Other Video Methods The One other method used to locate a target is to use frame grabbing to compare a known image (complex shape) with a “stored” replica of the target. This might include a face, a ball, a hockey puck, etc. This might be used in a future game as it seems that cameras are playing an accelerated part in game playing
