新方法改进了带叶三维树木建模和生物量估算

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-14 04:00

研究人员开发了一种新的点云三维树木建模和生物量估算方法，专门解决了叶子的挑战。该方法采用一种拓扑驱动的叶子抑制技术，在重建过程中取代了显式的叶-木分类。通过分析来自一次 Dijkstra 运行的短路径树结构，该方法准确地恢复了分支层次结构，在有叶条件下优于现有的辅助分离管道。 AI

影响通过增强三维建模技术，这项研究可以提高森林清单和生物量估算的准确性，尤其是在具有挑战性的有叶条件下。

用于叶片鲁棒性三维树木建模和点云地上生物量估算的短路径分解

arXiv:2506.15577v2 Announce Type: replace Abstract: Estimating above-ground biomass (AGB) from terrestrial laser scanning (TLS) via quantitative structural models (QSMs) is highly accurate under leaf-off conditions, yet major QSM paradigms degrade sharply when foliage is present.…
