Examples

Examples live under crates/*/examples/ and are built per crate. The facade examples under calib-targets take an image path directly; the lower-level crate examples synthesize their own inputs or accept a JSON config file (defaults point to testdata/ or tmpdata/).

To run an example from the workspace root:

# Standalone projective-grid — synthesizes its own oriented features:
cargo run -p projective-grid --example hello_grid

# Image-in / detection-out via the facade crate:
cargo run -p calib-targets --example detect_chessboard -- testdata/mid.png

The standalone projective-grid crate ships three onboarding examples that need no image files — hello_grid (the minimal detect-a-grid quickstart), detect_square_oriented2 (a larger detection run), and check_square_consistency (scoring caller-supplied labels). The image-free chessboard detector has its own minimal onboarding program, cargo run -p calib-targets-chessboard --example detect_chessboard.

Python examples live under crates/calib-targets-py/examples/ and use the calib_targets module. After maturin develop, run them with an image path, for example:

python crates/calib-targets-py/examples/detect_charuco.py testdata/small2.png
python crates/calib-targets-py/examples/detect_puzzleboard.py testdata/puzzleboard_small.png

See the sub-chapters for what each example produces and how to interpret the outputs.
