[Project] iMarkers: Imperceptible Fiducial Markers
April 2022 - March 2026
Affiliation: Doctoral Researcher, Interdisciplinary Research Project, University of Luxembourg
Target Audience: Robotics & Augmented Reality (AR) Research Communities
Project Ecosystem: Web-page | Article | GitHub (Standalone) | GitHub (ROS-based) | Paper
- Unobtrusive Fiducial Markers: next-generation, interdisciplinary tracking system that solves the visual aesthetic limitations of traditional robotics tracking.
- Aesthetic-Preserving Human Obscurity: innovative material engineering that leaves markers invisible or barely noticeable to the naked human eye, allowing seamless deployment in consumer and public environments.
- High-Fidelity Robotic Tracking: optimizes robot navigation, precise object recognition, and deep scene understanding by remaining highly visible to automated systems equipped with specialized sensors.
- Customizable Visibility Spectrum: offers production flexibility to customize the exact optical visibility range and underlying data-encoding algorithms based on specific scenario demands.
- 💡 Stack: Python, C++, OpenCV, ROS
