Annotated approximate 3D symmetric trees based on particle flow simulation and predefined tree crown shape

This dataset contains approximately symmetric 3D tree models with manually identified symmetry plane in each tree model. Each tree contains geometric data of branches, manually defined parameters for tree synthesis method, point clouds, and a division plane with a score of symmetry strength. Additionally, source code of the application for interactive manual approximate symmetry identification is supplied.

本数据集包含近似对称的三维（3D）树木模型，每棵树木模型均配有经人工识别的对称平面（symmetry plane）。每棵树木模型均包含枝干几何数据、用于树木合成方法的人工定义参数、点云（point clouds），以及带有对称强度评分的分割平面（division plane）。此外，本数据集还附带了用于交互式人工近似对称识别的应用程序源代码。
