A Factor Graph Optimization Method for High-Precision IMU-Based Navigation System
IEEE Transactions on Instrumentation and Measurement, 2023Multisensor-integrated navigation systems based on factor graph are increasingly used on indoor robots, UAVs, and other vehicles. The output information of the equipped low-cost inertial measurement unit (IMU) is usually processed by IMU preintegration ...

Covariance Estimation for Pose Graph Optimization in Visual-Inertial Navigation Systems
IEEE Transactions on Intelligent Vehicles, 2023Pose graph optimization helps reduce drift accumulated in pure odometry of visual simultaneous localization and mapping (SLAM) systems by solving a nonlinear least square problem, including both sequential constraints and loop-closing constraints ...

A High-Precision LiDAR-Inertial Odometry via Kalman Filter and Factor Graph Optimization
IEEE Sensors Journal, 2023For simultaneous localization and mapping (SLAM) in large-scale scenarios, the influence of long-distance and high-speed motion cannot be ignored because the risk of huge odometry drift will increase. To solve this problem, we propose the LiDAR -inertial

The Message Complexity of Distributed Graph Optimization
Information Technology Convergence and Services, 2023The message complexity of a distributed algorithm is the total number of messages sent by all nodes over the course of the algorithm. This paper studies the message complexity of distributed algorithms for fundamental graph optimization problems.
