Leaf-wood annotated tropical tree point clouds from terrestrial laser scanning

Dataset containing 148 manually leaf-wood annotated tropical tree point clouds. Point clouds were collected with a terrestrial laser scanner (RIEGL VZ-400) in northeastern Australia.

The tree point clouds are given as .txt files, with the first three columns being the local x,y,z coordinates (z=height). The fourth column is the label (0 = leaf, 1 = wood). The trees are organised in a train, validation and test folder, to train and evaluate machine/deep learning models.

Tee species information and more information on the plots can be found in the excel file 'additional_tree_and_plot_info.xlsx'.

本数据集包含148株经人工完成叶、木类别标注的热带树木点云（point cloud）。所有点云均通过澳大利亚东北部地区的地面激光扫描仪（RIEGL VZ-400）采集获取。

该树木点云以.txt文件格式存储，其前三个列为局部坐标系下的x、y、z坐标（其中z轴代表高度），第四列为类别标签（0代表叶片，1代表木质部分）。数据集按训练集、验证集与测试集文件夹进行组织，以用于机器学习/深度学习模型的训练与评估。

树木物种信息以及样地的更多详细信息可查阅Excel文件'additional_tree_and_plot_info.xlsx'。
