About

Seo-Yeon Hwang is a leading figure in mobile robotics, specializing in low-cost, vision-based navigation for indoor environments. Her research focuses on solving the fundamental challenge of simultaneous localization and mapping (SLAM) using a single, upward-looking monocular camera. By leveraging ceiling features—such as corners, lamps, and doors—as reliable landmarks, Hwang has developed robust systems that overcome the limitations of traditional ground-level sensors. Her seminal 2011 paper on monocular SLAM using these features has garnered over 105 citations, establishing a foundational approach for affordable indoor robot navigation. She further advanced the field by tackling the critical problem of "indistinguishable features" on ceilings, which often cause localization failures due to false data associations. Hwang’s work also includes a novel global localization scheme that matches ceiling features to a pre-built map, enabling a robot to determine its pose even when starting from an unknown location. Her integration of upward-looking cameras with sonar sensors for autonomous navigation demonstrates a practical, multi-sensor approach to reliable indoor mobility. Through these contributions, Hwang has significantly advanced the practicality and dependability of monocular SLAM for real-world service robots.
