机载激光雷达森林灌层重建
Airborne LiDAR Data for Rebuilding Tree Canopy

利用机载激光雷达点云数据在植被冠层分布,计算叶片密度在植被冠层垂直方向上的分布,进行冠层三维形状的精确重建,并结合地面实测数据,建立植被结构参数(叶面积指数,生物量,碳储量等)的反演模型。

According to the spatial distribution of LiDAR point cloud within a tree canopy, two vegetation attributes can be obtained: (1) leaf density can be accurately estimated for each vertical layer; (2) 3D canopy shape can be reconstructed for a tree. Statistical models with the two attributes can be developed for estimating vegetation structural characteristics (e.g. biomass, LAI, carbon).
