Fiducial markers play a crucial role in localization, navigation, and tracking systems, particularly in robotics. However, widely used marker detection methods relying on RGB cameras often fail in low-light or no-light environments, where traditional black-and-white markers become ineffective. To address this challenge, we propose a Variable Lighting Conditions Fiducial Marker (VLCFM) system that enhances detection accuracy across diverse lighting conditions, ensuring reliable performance in complete darkness while remaining undetectable to the human eye.
