VILO SLAM: Tightly Coupled Binocular Vision–Inertia SLAM Combined with LiDAR
Sensors, 2023 For the existing visual–inertial SLAM algorithm, when the robot is moving at a constant speed or purely rotating and encounters scenes with insufficient visual features, problems of low accuracy and poor robustness arise.

Continuous-Time Spline Visual-Inertial Odometry
2022 International Conference on Robotics and Automation (ICRA), 2022 We propose a continuous-time spline-based formulation for visual-inertial odometry (VIO). Specifically, we model the poses as a cubic spline, whose temporal derivatives are used to synthesize linear acceleration and angular velocity, which are compared to the measurements from the inertial measurement unit (IMU) for optimal state estimation. The spline
