A GTSAM-Based Monocular Visual-Inertial Odometry for Indoor UAVs: Robust Initialization and Single-Configuration Validation on EuRoC
This paper presents a tightly coupled monocular point-feature visual-inertial odometry (VIO) system for that setting, realized on a GTSAM fixed-lag factor graph with inverse-depth landmarks, on-manifold IMU preintegration, and an online loop-closure pose graph.
