Description: Researchers created a multi-tag fiducial called quARtet by tilting four AprilTags in one footprint to improve pose estimation accuracy from near-frontal views. The system uses a shared configuration file to generate geometry and detect markers. The study shows that the best layout depends on whether pose consistency or physical graspability is more important.
