CKF-Based Visual Inertial Odometry for Long-Term Trajectory Operations

Journal of Robotics, 2020
The estimation error accumulation in the conventional visual inertial odometry (VIO) generally forbids accurate long-term operations. Some advanced techniques such as global pose graph optimization and loop closure demand relatively high computation and ...
