Chessboard Detection Example

File: crates/calib-targets-chessboard/examples/chessboard.rs

This example runs the full chessboard pipeline:

Example output overlay for chessboard detection.

1. Detects ChESS corners using the chess-corners crate.
2. Adapts them to calib_targets_core::Corner.
3. Runs ChessboardDetector.
4. Optionally outputs debug data (orientation histogram, grid graph).

The default config is testdata/chessboard_config.json (input: testdata/mid.png, output: tmpdata/chessboard_detection_mid.json).

Run it with:

cargo run -p calib-targets-chessboard --example chessboard -- testdata/chessboard_config.json

The output JSON contains detected corners, grid coordinates, and optional debug diagnostics (if debug_outputs are enabled in the config).
