About
Dr. Changhui Xu is a leading researcher in autonomous navigation and robotics, with a primary focus on robust visual-inertial simultaneous localization and mapping (SLAM) systems. His most cited work, "Robust Visual-Inertial Navigation System for Low Precision Sensors under Indoor and Outdoor Environments" (2021, 26 citations), addresses a critical challenge in SLAM: the vulnerability of vision-based systems to poor lighting and low-texture environments, which cause scale ambiguity and drift. Dr. Xu’s major contribution lies in developing a tightly-coupled sensor fusion framework that integrates low-cost inertial measurement units with monocular cameras, enabling reliable state estimation even with inexpensive hardware. This innovation significantly improves the practicality of SLAM for real-world applications, from autonomous drones to mobile robots operating in both indoor and outdoor settings. By mitigating the scale ambiguity problem without requiring high-precision sensors, his work has opened new avenues for affordable, robust navigation systems. Dr. Xu’s research continues to push the boundaries of resilient perception, making him a key figure in advancing field-deployable robotics.
