Fiducial Marker

Fiducial markers are artificial landmarks, often visually encoded patterns, used for robust localization and mapping in various robotic and computer vision applications. Current research focuses on improving marker detection and pose estimation using techniques like YOLO-based object detection, adaptive exposure control for challenging environments (e.g., underwater), and advanced graph-based optimization methods for multi-view point cloud registration. These advancements enhance the accuracy and reliability of marker-based systems, impacting fields such as autonomous navigation (UAVs, AUVs, mobile robots), 3D mapping, and multi-sensor calibration, particularly in scenarios with limited or unreliable GPS signals.
