要旨本文 Accurate classification of tree components is crucial for forest management, biodiversity monitoring, and ecological research. UAV-based LiDAR provides high-density point clouds with potential for detailed forest analysis, but segmenting these into meaningful entities remains challenging. To fill this gap, we propose a novel method using UAV LiDAR-derived point cloud data and an enhanced Attention-PointNet++ model. This approach leverages high-resolution data and attention mechanisms to improve the classification of tree components, including trunks, branches, coarse woody debris (CWD), and ground. Tested on labeled data from the University of Tokyo Hokkaido Forest (UTHF), the method achieved a high F1-score across four semantic classes, demonstrating its accuracy and efficiency. This approach has promising applications for forest inventory, monitoring, and ecosystem modeling, providing deeper insights into forest vertical structure and enhancing ecological understanding.
