Bowling lane scorer from a photo of the pins

A community centre replaced a six-figure scoring system with a few ESP32s and a camera. Build the scoring core: from a photo of the pin deck to a correct frame score, including strikes, spares and the tenth frame.

Requirements

A function that takes a top-down image of ten pin positions (samples in the repo) and returns which pins are standing

Full ten-pin scoring rules, with the tenth-frame bonus balls, as a pure module with tests

A lane display web page: current frame, running score, whose turn

Correct a mis-detected pin by tapping it on the display

Handle a foul and a gutter ball

Technical Notes

Detection can be simple — the pin positions are fixed and the lighting is controlled. Do not reach for a neural net.

Starter repo

You connect the GoShip MCP server to Claude Code or Cursor. It records your prompts, tool calls and test runs, and that record is what gets scored.
