Cricket umpire assistance and ball tracking system that using video from a single smartphone camera.

Instructions

  • Run python object_detector/ballTracking.py with the following arguments:
    • -v/--video (Required): Path to the video file
    • -a/--attack (Optional): Specify bowling attack - 1 for Spin bowling and 0 for Fast
    • -s/--sliding (Optional): Show sliding windows during ball detection
    • -f/--first (Optional): First frame number
  • This will save run the ball tracking algorithm and generate the 3D coordinates of the tracked ball, which will be written to coordinates.txt in the form:
    • x,y,radius,frame_no,is_bouncing_point, linear_reg_radius, quad_reg_y
  • Finally run python object_detector/3d.py which uses the coordinates generated by ballTracking.py to visualize the trajectory and output the umpiring decisions.

GUI

To use the GUI for running the tracking and visualization scripts directly, run python gui/gui.py. The GUI requires the Kivy library to be installed.

(The python_bin paths in gui/gui.py and path to the object_detector and gui directories will have to be updated accoridng to the local machine before running the GUI.)

Video

You can see the frame-by-frame visualization of the tracked ball here: https://www.youtube.com/watch?v=K9MP5UlGBEI
