DartPi: Automated Dart Score Detection System

This project aims to automate dart score detection using Raspberry Pi, solving the annoyance of manual counting. It utilizes OpenCV, C++, and webcams for accuracy. Despite challenges like webcam issues and limited Raspberry Pi performance, it promises a convenient solution for dart enthusiasts. Both the background model initialization process and the dart detection algorithm contribute to accurate score calculations. Follow along the development journey and see how this innovative system enhances the dart-playing experience.

  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?
