Fiducial Tag Localization

Fiducial tag localization focuses on accurately determining the 3D position and orientation of artificial markers (fiducial tags) within an environment, using various sensor modalities like cameras and LiDAR. Current research emphasizes real-time performance, particularly for applications like UAV navigation, often employing lightweight object detectors (e.g., YOLO) and efficient pose estimation algorithms (e.g., Perspective-n-Point). This technology is crucial for improving the accuracy and reliability of robotic systems, particularly in GPS-denied environments, enabling advancements in areas such as autonomous navigation, motion capture, and precise asset tracking.
