On April 14, 2025, Professor Rafael Muñoz-Salinas from the University of Córdoba, Spain, invited by  Associate Professor Shiqi Yu from the Research Institute of Trustworthy Autonomous Systems (RITAS) delivered a talk on fiducial markers to faculties‌ and students at SUSTech.

Fiducial markers are high-contrast visual tags used for object localization and pose estimation, which play an essential role in fields such as robotics, augmented reality, and autonomous systems. Professor Muñoz-Salinas is the creator of the widely used ArUco marker, one of the fiducial markers. With years of research experience in fiducial markers, Professor Muñoz-Salinas shared recent advancements in fiducial markers, including work on enhancing marker detection in low-light and noisy environments using deep learning techniques. He also introduced his team’s latest developments in the design of 3D and customizable fiducial markers. These innovations aim to bridge the gap between technical precision and practical usability in real-world applications.

Following the lecture, several students presented their own work on fiducial markers to Professor Muñoz-Salinas, including a new deep learning model for fiducial markers, QR codes etc.,and Professor Muñoz-Salina gave suggestions on how to improve their work. This led to in-depth discussions and valuable exchanges of ideas between the students and the professor, strengthening the collaboration between the two research groups.
