  1. DartPiAutomatic Dart Score Detection using Raspberry Pi Christian Hirsch

  2. Content • Motivation • Development Environment • Approach/Progress • Problems • Videos DartPi – Automatic Dart Score Detection

  3. Motivation • „Analog“ dart is cooler • Darts can hurt • You see that you‘ve played • Manual counting is annoying • A PC or notebook is too big/expensive • Raspberry Pi is the solution DartPi – Automatic Dart Score Detection

  4. Development Environment • For Testing: • Open CV 2.4.3, C++ • Microsoft Visual Studio 2010 • Videos • Final version • RaspberryPi, Raspbian • OpenCV 2.3.?, g++, make • „analog“ Dartboard + 2 Webcams DartPi – Automatic Dart Score Detection

  5. Approach/Progress • Detect dartboard + markings • Detect darts • Check whether someone shot a dart or player changed • Equip dartboard with webcams • Compile the program on Raspbian • Count the dart-score • Create a userinterface (?) • Handle user interactions DartPi – Automatic Dart Score Detection

  6. your title

  7. Would be nice but … DartPi – Automatic Dart Score Detection

  8. … not possible  DartPi – Automatic Dart Score Detection

  9. Possible … your title

  10. Possible … DartPi – Automatic Dart Score Detection

  11. Dart Detection - Process • Initialize background model • for each camera • Check if something changes • small changes in short time -> dart • big changes, long time -> change • anyting else -> error • Get dartboard + dart contours • calculate position • calculate points • Return points DartPi – Automatic Dart Score Detection

  12. your title

  13. Real Problems • GLS • Webcams • no wideangle • Raspberry Pi performance • Image resolution of 320x240 px used • Errors • Maybe one webcam does not work correctly DartPi – Automatic Dart Score Detection

  14. Thank you & good night Questions?
