Cricket pitch map

Open source, roboflow/sports

Solo, open-source contribution

Broadcast clip of one cricket delivery, with the ball's path traced in yellow down to where it bounces. Beside it, a top-down pitch map split into length zones (yorker, full, good, back of length, short) plots that bounce: good length, 6.5 m, outside off.

Finds where the ball bounces from TV broadcast video, accurate to within 21 cm. YOLOv8 detection and pose, OpenCV homography and camera calibration, 704 hand-labelled frames, held-out evaluation, pytest.

How I work with AI agents

  • I write the Project Context before the first ticket, and fix it when a worker shows me it's wrong.
  • I split tickets so parallel workers touch different files. Three ran at once on this page with no merge conflicts.
  • When a number I asked for turned out wrong, I fixed the spec, not just the output (PR #5).

How this page was built

Every merged pull request in this repo, read from the GitHub API when the site was built.
