GVI-Switch: A High-Precision GNSS-Visual-Inertial State Estimator for Indoor-Outdoor Environments
We propose a high-precision GNSS-visual-inertial state estimator named GVI-Switch, augmented with a loosely coupled Error State Kalman Filter (ESKF), to achieve stable six-degree-of-freedom (6-DoF) pose estimation under varying GNSS signal conditions. First, we developed a GNSS degradation detection
