1) Using video cameras on a robot allows it to find and determine the direction and distance to targets through techniques like masking and shape recognition. 2) Masking provides an image of only the target object, like a flag, which can then be used to determine distance from the robot from 2 feet away and further. Cameras can also pan and tilt to extend the visual range. 3) Pattern recognition software in 2010 identified a bullseye target above the goal by analyzing the video image and returning data on the target's position, score, and angle offset based on the radius ratios.

- 2. IntroductionUsing one or more Video Cameras on a robot allows for target finding , direction to the target and distance to the targetCameras can use “Masking” an/or “Shape Recognition”2
- 4. The Video CameraObject (Trailer) detection
- 5. Use to find and determine friend or foe4Use to determine distance and direction to flag (good distance measurement from 2 feet and up)
- 6. Can be used with servos to pan and tilt the camera to extend the visual bound
- 7. Masking provides image of only flag (can mask other defined objects as well)Masking Using the Video CameraNote an example of masking that was used in the 2009 competition. The “Flag Location” gauge shows not only the direction to the target but also the relative size of the target which is used to determine the distance from the robot.
- 8. Pattern RecognitionViewing a target with a defined mathematical representationIn 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 MethodsThe 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
