What's Happening?
Recent advancements in unmanned aerial vehicles (UAVs) have led to the development of LiDAR-based quadrotors designed for slope inspection under dense vegetation. These quadrotors utilize high-precision 3D measurements from LiDAR sensors, allowing them to navigate complex terrains and access areas that are challenging for humans or ground robots. The system incorporates a robust LiDAR-inertial odometry framework, FAST-LIO2, which operates effectively in GPS-denied environments. Enhancements in mapping techniques, such as unknown grid cells inflation and incremental frontier updates, enable efficient obstacle avoidance and safe navigation. The quadrotors are equipped with advanced hardware, including the Livox Mid-360 LiDAR and Intel NUC minicomputer, providing substantial computational power for real-time processing. This technology promises to reduce human labor and operational risks while enhancing work efficiency in slope inspections.
