Mesh Rectification Example

File: crates/calib-targets-aruco/examples/rectify_mesh.rs

This example detects a chessboard, performs per-cell mesh rectification, and scans the rectified grid for ArUco markers. It writes:

Mesh rectification output Per-cell mesh rectification output from the small test image.

  • A mesh-rectified grayscale image.
  • A JSON report with rectification info and marker detections.

The code defaults to testdata/rectify_mesh_config_small0.json, and that config is a good starting point (input: testdata/small0.png, mesh output: tmpdata/mesh_rectified_small0.png, report: tmpdata/rectify_mesh_report_small0.json).

Run it with:

cargo run -p calib-targets-aruco --example rectify_mesh -- testdata/rectify_mesh_config_small0.json

This is a good reference for the full grid -> rectification -> marker scan pipeline.
