On 15 December, Dr. Wen was invited to give a lecture at Lanzhou University titled “3D LiDAR Aided (3DLA) Urban GNSS Positioning for Autonomous Systems in Urban Canyons”. The lecture focuses on the challenges and advances in urban positioning for autonomous driving vehicles (ADV).
Poster of the lecture at Lanzhou University.
As cities become more urbanised, the accuracy of global navigation satellite systems (GNSS) is degraded by signal reflections from buildings and vehicles, leading to non-line-of-sight (NLOS) reception. Dr. Wen will discuss his work on perception-aided NLOS mitigation methods that use 3D LiDAR to reconstruct the environment and improve GNSS accuracy. This research received the Best Presentation Award, recognised by industry leaders from Waymo and Swift Navigation, and has been successfully applied in high-accuracy offline mapping.
Dr. Wen will also present recent progress in extending these methods to GNSS Real-time Kinematic (RTK) positioning, achieving sub-meter accuracy. The lecture offers insights into overcoming urban navigation challenges and into the future of intelligent transportation systems.
