Orchard Navigation of UGVs Using UAV-LiDAR-Based Semantic Costmap

Journal of Robotics and Mechatronics
This study proposes a costmap generation method for orchard navigation that integrates both semantic and geometric information from point clouds acquired using unmanned aerial vehicle (UAV)-based light detection and ranging (LiDAR). Conventional approaches often rely on aerial imagery, which cannot capture the internal structures of tree crowns, or ...

Sea Surface Height Measurements Using UAV Altimeters with Nadir LiDAR or Low-Cost GNSS Reflectometry

Remote Sensing
Although UAV height is precisely determined using GNSS, the vertical distance between the UAV and the sea surface should be subtracted to obtain the sea surface height (SSH).
