Researchers have developed a new framework for autonomous operation in GPS-denied environments, utilizing specially designed markers made from Cholesteric Spherical Reflectors (CSRs). These markers act as pre-surveyed visual anchors to georeference mapping data from LiDAR and other sensors, ensuring a consistent spatial reference without relying on satellite navigation. The system demonstrated significant improvements in correcting positional drift and improving cross-session accuracy, with marker processing operating in real-time. AI
