What it does
- Subscribes to a camera image topic and its camera_info topic, both in the same namespace.
- Detects ArUco markers in incoming images and publishes their poses on an aruco_detections topic.
- Publishes detected marker poses on TF so they can be visualized in RViz.
- Publishes a debug image topic with marker frame axes drawn over the camera image.
- Provides a managed lifecycle node that must be configured and activated, plus an autostart variant.
- Includes a create_marker script that generates PDF files of ArUco markers with a chosen ID.
