Individual Tree Segmentation Based on Region-Growing and Density-Guided Canopy 3-D Morphology Detection Using UAV LiDAR Data
Forest tree information is crucial for monitoring forest resources and developing forestry management strategies.Airborne laser scanning is an efficient and rapid method for acquiring 3-D point cloud data of forests, making up for the shortcomings of optical remote sensing.Especially for unmanned aircraft vehicle laser scanning, the high-density po
