ROS Apriltag Detector

This repository holds the following ROS2 packages for detecting and displaying Apriltags:

• apriltag_detector: base class definitions for plugable detector libraries, launch files for detecting and displaying apriltags. This is the package typically used.

The following packages are accessed mostly through the above apriltag_detector package.

• apriltag_draw: components for drawing detected Apriltags onto images.
• apriltag_umich: plugable library and component for detecting Apriltags using the UMich implementation.
• apriltag_mit: plugable library and component for detecting Apriltags using the MIT implementation.

The software in this repository does strictly perception, no camera pose estimation! It is typically used when no camera calibration is available, or is not needed. If you want perception and camera pose together, use this package, which uses the same tag message format.
