A Lidar-Inertial Navigation System for UAVs in GNSS-Denied Environment with Spatial Grid Structures

With its fast and accurate position and attitude estimation, the feature-based lidar-inertial odometer is widely used for UAV navigation in GNSS-denied environments. However, the existing algorithms cannot accurately extract the required feature points in the spatial grid structure, resulting in red...
