3D LiDAR Aided GNSS NLOS Mitigation in Urban Canyons
Weisong Wen, Li-Ta Hsu
In this paper, we propose a 3D LiDAR aided global navigation satellite system (GNSS) non-line-of-sight (NLOS) mitigation method caused by both static buildings and dynamic objects.…
Time-correlated Window Carrier-phase Aided GNSS Positioning Using Factor Graph Optimization for Urban Positioning
Xiwei Bai, Weisong Wen, Li-Ta Hsu
This paper proposes an improved global navigation satellite system (GNSS) positioning method that explores the time correlation between consecutive epochs of the code and carrier p…
GNSS Outlier Mitigation Via Graduated Non-Convexity Factor Graph Optimization
Weisong Wen, Guohao Zhang, Li-Ta Hsu
Accurate and globally referenced global navigation satellite system (GNSS) based vehicular positioning can be achieved in outlier-free open areas. However, the performance of GNSS…
Towards Robust GNSS Positioning and Real-time Kinematic Using Factor Graph Optimization
Weisong Wen, Li-Ta Hsu
Global navigation satellite systems (GNSS) are one of the utterly popular sources for providing globally referenced positioning for autonomous systems. However, the performance of…
Semantic 3D Map Change Detection and Update based on Smartphone Visual Positioning System
Max Jwo Lem Lee, Li-Ta Hsu
